Explanation:

Answer:

the pOH of a solution is the negative logarithm of the hydroxide-ion concentration. by this yields a [OH − ] of 1.0 × 10 -10 M. Finally the pOH of the solution equals -log(1.0 × 10 -10 ) = 10.Explanation:

The concentration of hydroxide ion of a solution whose pOH value is equal to 2.86 is 1.38×10⁻³ M.

Concentration of hydroxide ion will be calculated by using the pOH value by using the below equation as:

pOH = -log[OH⁻]

[OH⁻] = \(10^{-pOH}\)

Given that value of pOH = 2.86

On putting values we get,

[OH⁻] = \(10^{-2.86}\)

[OH⁻] = 0.00138 = 1.38×10⁻³ M

Hence concentration of hydroxide ion is 1.38×10⁻³ M.

a.)  The Volume of water displaced is  3 ml

b.)  The final density of the mineral is 4.1 g/ml.

(a) The volume of water displaced is the ratio of the volume containing mineral to the volume excluding mineral.

Volume of water displaced = Volume with mineral - Volume without mineral

Volume of water displaced = 53 ml - 50 ml

Volume of water displaced = 3 ml.

(b) The following formula can be used to determine the mineral's density:

Mass / Volume equals density.

The difference between the mass of the mineral and the mass without the mineral is the mass of the mineral.

Mass of mineral = Mass with mineral - Mass without mineral

Mass of mineral = 12.3 g - 0 g (since the mass without mineral is not given)

Mass of mineral = 12.3 g

By deducting the volume without the mineral from the volume with, one may determine the volume of the mineral.

Volume of mineral = Volume with mineral - Volume without mineral

Volume of mineral = 53 ml - 50 ml

Volume of mineral = 3 ml

Therefore, the density of the mineral is:

Density = Mass of mineral / Volume of mineral

Density = 12.3 g / 3 ml

Answer:

detail is given below.

Explanation:

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O  → C₆H₁₂O₆ + 6O₂

The given equation is balanced chemical equation of photosynthesis. There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

If equation is not balanced,

CO₂ + H₂O  → C₆H₁₂O₆ + O₂

It can not follow the law of conservation of mass because mass is not equal on both side of equation.

A twin-turbojet airplane is cruising with a speed of Mach 1.5 at an altitude where atmospheric pressure is 32989.5 Pa, temperature is 232.778 K. Each engine is consuming 200 kg of air per second. The engine exit flow has a pressure of 32,000 Pa with a velocity of 850 m/sec. The exit area of the engine nozzle is 1.4 m². The thrust generating in both engines is 342,678.6 Newtons.

To calculate the thrust generated by both engines, we can use the momentum equation for a nozzle:

Thrust = mass flow rate * exit velocity + (exit pressure - ambient pressure) * exit area

Given:

Speed of the airplane (V) = Mach 1.5

Atmospheric pressure (\(P_a\)) = 32989.5 Pa

Ambient temperature (\(T_a\)) = 232.778 K

Mass flow rate of each engine (m) = 200 kg/s

Exit pressure of the engine (\(P_e\)) = 32000 Pa

Exit velocity of the engine (\(V_e\)) = 850 m/s

Exit area of the engine nozzle (\(A_e\)) = 1.4 m²

First, we need to calculate the ambient density using the ideal gas law:

PV = nRT

Since the speed of the airplane is given in terms of Mach number, we can calculate the speed of sound (a) using the following formula:

a = √(gamma * R * \(T_a\))

Where gamma is the specific heat ratio of air (approximately 1.4) and R is the specific gas constant for air (approximately 287 J/(kg K)).

Next, we can calculate the ambient density (ρ) using the equation:

ρ = \(P_a / (R * T_a)\)

Now, we can calculate the thrust generated by each engine using the momentum equation:

Thrust = m* \(V_e + (P_e - P_a) * A_e\)

Finally, we can calculate the total thrust generated by both engines by multiplying the thrust of a single engine by 2.

Calculate the speed of sound:

a = √(1.4 * 287 * 232.778)

a = 438.95 m/s

Calculate the ambient density:

ρ = 32989.5 / (287 * 232.778)

ρ = 1.383 kg/m³

Calculate the thrust of a single engine:

\(Thrust_s\) = 200 * 850 + (32000 - 32989.5) * 1.4

\(Thrust_s\) = 170000 + 1339.3

\(Thrust_s\)  171339.3 N

Calculate the total thrust of both engines:

\(Thrust_t\) = 2 * \(Thrust_s\)

\(Thrust_t\) = 2 * 171339.3

\(Thrust_t\) = 342678.6 N

Therefore, both engines are generating approximately 342,678.6 Newtons of thrust.

The leaves of plants primarily serve to photosynthesize and require water conducted by the root to do so.

As a leaf of a plant running low on supplies that the root is responsible for, what I will be needing is water.

Thus, I will have to send a text message to the root to supply me with water. The root will respond by asking its foot soldiers (the root hairs) to conduct water into the root.

Once water gets into the root, it enters special cells that are responsible for conducting water inside plants - the xylems. The root sends the water through the xylem and water travels from there to me - the leaf.

Once the water gets to me, I will use it in combination with inorganic carbon (carbon dioxide) to synthesize carbohydrates.

Though not entirely accurate, 'A' is the best possible answer.

Water is considered the universal solvent.  Water is polar and has a partially positive and negative charge, it readily dissolves ions and polar molecules. When an ionic substance is added to water, individual ions interact with the polar regions of the water molecules during the dissociation process, disrupting their ionic bonds. The charges associated with these molecules form hydrogen bonds with water, surrounding the particle with water molecules. This is referred to as a sphere of hydration, or a hydration shell, and serves to keep the particles separated or dispersed in the water.

A pi bond is the result of the d) sideways overlap of two parallel p orbitals.

Pi bonds are bonds that occur as a result of overlapping orbitals of atoms that are not in the bond axis. Each p orbital that contributes to a pi bond has two lobes and has a node at the core.

The pi orbital can hold a maximum of two pairs of electrons. Whereas each electron in a pi bond is also called a pi electron, the pi electrons are used for double bonds or triple bonds. The 2p orbital of carbon has slightly higher energy than the sp2 orbital, so the pi bond formed from two 2p orbitals has somewhat higher energy and is slightly less stable than the sp2-sp2 sigma bond.

The Fahrenheit temperatures corresponding to Celsius 31°C, 21°C, -9°C, and -15°C are approximately 88°F, 70°F, 16° F, 5°F.

To find the equation relating Fahrenheit temperature (F) to Celsius temperature (C), we can use the given freezing and boiling points of water on both scales.

We know that at the freezing point of water:

Fahrenheit temperature = 32°F

Celsius temperature = 0°C

And at the boiling point of water:

Fahrenheit temperature = 212°F

Celsius temperature = 100°C

We can use these two points to find the equation of the line relating F and C.

First, we find the slope of the line:

Slope = (Change in Fahrenheit temperature) / (Change in Celsius temperature)

= (212°F - 32°F) / (100°C - 0°C)

= 180°F / 100°C

Next, we find the y-intercept of the line:

Using the freezing point of water (0°C, 32°F):

32°F = Slope * 0°C + y-intercept

32°F = 0.18 * 0°C + y-intercept

y-intercept = 32°F

Therefore, the equation relating Fahrenheit temperature (F) to Celsius temperature (C) is:

F = 1.8C + 32

Now, we can use this equation to find the Fahrenheit temperatures corresponding to the given Celsius temperatures:

For 31°C:

F = 1.8 * 31 + 32 = 87.8 ≈ 88°F

For 21°C:

F = 1.8 * 21 + 32 = 69.8 ≈ 70°F

For -9°C:

F = 1.8 * -9 + 32 = 15.8 ≈ 16°F

For -15°C:

F = 1.8 * -15 + 32 = 5 ≈ 5°F

Therefore, the Fahrenheit temperatures corresponding to 31°C, 21°C, -9°C, and -15°C are approximately 88°F, 70°F, 16° F, 5°F.

(iii) The degree of polymerization (DP) is 4492.

(i) Number average (Mn)

The number average molecular weight (Mn) is the sum of the molecular weights of all polymer chains divided by the total number of polymer chains.

Weight average (Mw)

The weight average molecular weight (Mw) is the sum of the product of the molecular weight and the fraction of the total polymer chains that have that molecular weight.

Using the given formula, let's first calculate the Mn:

(2100 + 6600 + 12000) / 3 = 6,900g/mol

Let's now calculate the Mw:

[(2100 x 2100) + (6600 x 6600) + (12000 x 12000)] / (2100 + 6600 + 12000)= 9966.67g/mol

(ii) Equal weights of chains

Mn will remain the same in this case as it does not depend on weight.

Mw, on the other hand, will change.

The following formula will be used:

2100 x (1/3) + 6600 x (1/3) + 12000 x (1/3) = 6,900g/mol

Triacylglycerols are the major form of stored energy instead of glucose because they have a higher energy density due to their hydrophobic nature, they can be easily transported in the blood serum, and they yield more energy per carbon upon oxidation compared to glucose.

Triacylglycerols are more advantageous as a stored energy form compared to glucose for multiple reasons. Firstly, triacylglycerols have a higher energy density because of their hydrophobic nature. They are not solvated by water and therefore have less mass per unit volume, allowing for more energy to be stored in the same volume.

Secondly, triacylglycerols are highly soluble in blood serum, enabling efficient transportation to different parts of the body where energy is needed. This solubility facilitates the mobilization and delivery of stored energy to meet metabolic demands.

Lastly, the fatty acids in triacylglycerols are at a higher reduction state compared to glucose. This higher reduction state means that fatty acids yield more energy per carbon upon oxidation. Thus, the oxidation of fatty acids in triacylglycerols provides a greater amount of energy compared to the oxidation of glucose, making them an efficient energy source for the body.

Overall, the combination of higher energy density, easy transportability, and greater energy yield per carbon make triacylglycerols the preferred form of stored energy in the body compared to glucose.

This equation shows the reaction between the bicarbonate ion (HCO3⁻) from the buffer and the hydroxide ion (OH⁻) from the added NaOH, producing the carbonate ion (CO3²⁻) and water (H2O).

In this equation, the Na2CO3 acts as a buffer to maintain the pH of the solution. The added NaOH reacts with the NaHCO3 to form water and CO32- ion, which increases the concentration of carbonate ion in the solution. However, the buffer system consisting of Na2CO3 and NaHCO3 resists changes in pH by neutralizing any additional OH- ions that are added. Therefore, the overall pH of the solution remains relatively constant.
When a buffer is prepared with Na2CO3 (sodium carbonate) and NaHCO3 (sodium bicarbonate), and a small amount of NaOH (sodium hydroxide) is added, the net ionic equation is as follows:
HCO3⁻(aq) + OH⁻(aq) → CO3²⁻(aq) + H2O(l)
This equation shows the reaction between the bicarbonate ion (HCO3⁻) from the buffer and the hydroxide ion (OH⁻) from the added NaOH, producing the carbonate ion (CO3²⁻) and water (H2O).

Yes, we can conclude from the results by Dr. Gore that increasing temperatures are caused by carbon emissions.

Multiple well-designed studies have decisively demonstrated that increased CO2 levels brought on by the burning of fossil fuels are to blame for global warming. The link between CO2 levels and rising temperatures is just more evidence. In addition to more warming being caused by higher CO2, more CO2 is also released as a result of warming in a number of other ways. This is referred to as a positive feedback loop in which increased CO2 results in warmth, which raises CO2, which raises warming, and so on. Unfortunately, those who reject man-made global warming frequently point out that rising temperatures cause a rise in CO2 in an effort to mislead people into believing that warming is not caused by increased CO2.

In a saturated solution of silver chromate (Ag2CrO4), the silver ion concentration is already given as 8.66 x 10^-5 M. We have to determine the concentration of silver ions in the solution when solid sodium chromate (Na2CrO4) is added.

When solid sodium chromate is added, it dissociates into sodium ions (Na+) and chromate ions (CrO4^2-). Since silver chromate is a sparingly soluble salt, it establishes an equilibrium between the dissolved ions and the solid salt.

The balanced chemical equation for the dissolution of silver chromate can be represented as:

Ag2CrO4 ⇌ 2 Ag+ + CrO4^2-

The addition of solid sodium chromate does not directly affect the concentration of silver ions (Ag+). However, it increases the concentration of chromate ions (CrO4^2-) in the solution. Given that the concentration of chromate ions (CrO4^2-) is 0.0600 M, and assuming that the dissociation of silver chromate is complete, the concentration of silver ions remains the same at 8.66 x 10^-5 M.

Therefore, the concentration of silver ions in a saturated silver chromate solution, when solid sodium chromate is added to form an additional 0.0600 M chromate ion, would still be 8.66 x 10^-5 M. The addition of sodium chromate increases the concentration of chromate ions but does not affect the concentration of silver ions.

The reason for the predominance of the keto form over the enol form in tautomeric equilibrium of carbonyl compounds is primarily due to thermodynamic stability and resonance stabilization.

The keto form, characterized by a carbonyl group (C=O), is more stable than the enol form, which contains a hydroxyl group (-OH) attached to a carbon-carbon double bond. This stability arises from the stronger double bond character of the carbon-oxygen bond in the keto form compared to the carbon-carbon bond in the enol form.

Resonance stabilization also contributes to the preference for the keto form. In the keto form, the lone pair of electrons on the oxygen atom can participate in resonance with the adjacent carbon-oxygen double bond. This delocalization of electrons enhances the stability of the keto form.

On the other hand, the enol form has a higher energy due to the presence of a carbon-carbon double bond and an oxygen-hydrogen single bond, which are generally less stable than the carbon-oxygen double bond in the keto form.

Overall, the thermodynamic stability and resonance stabilization of the keto form make it the more favorable tautomer, leading to its predominance over the enol form in most carbonyl compounds.
