The concentration of each solution is 7.625 x 10⁻³ m, 3.8125 x 10⁻⁴ m, and 1.90625 x 10⁻⁵ m.

Dilution is defined as the process in which the concentration of a sample is decreased by adding more solvent. The dilution formula is given below.

C₁V₁ = C₂V₂

where C₁ = initial concentration of sample

V₁ = initial volume of sample

C₂ = final concentration after dilution

V₂ = total final volume after dilution

Plug in the values to the formula and solve for the concentration of the diluted solution.

1st standard solution

C₁V₁ = C₂V₂

0. 1525 m(5.00 ml) = C₂(100.0 ml)

C₂ = 7.625 x 10⁻³ m

2nd standard solution

C₁V₁ = C₂V₂

7.625 x 10⁻³ m(5.00 ml) = C₂(100.0 ml)

C₂ = 3.8125 x 10⁻⁴ m

3rd standard solution

C₁V₁ = C₂V₂

3.8125 x 10⁻⁴ m(5.00 ml) = C₂(100.0 ml)

C₂ = 1.90625 x 10⁻⁵ m

Explanation:

Rb (rubidium) has the highest first ionization energy of the elements listed. This is because Rb has the highest atomic number (37) out of the elements given. The higher the atomic number of an element, the higher its ionization energy.

Atomic number is a number that represents the number of protons in an atom's nucleus. It is also referred to as the proton number and is usually denoted by the symbol Z. The atomic number uniquely identifies a chemical element and is identical to the charge number of the nucleus. The atomic number of an element can range from 1 (hydrogen) to as high as 118 (ununoctium), and each element has a unique atomic number. For example, carbon has an atomic number of 6, oxygen has an atomic number of 8, and helium has an atomic number of 2. The periodic table of elements is arranged according to the atomic number of each element, which allows for an easy comparison of elements and their properties.

Reference table F lists the solubility of various compounds in water at 25°C. According to the table, the solubility of silver iodide in water is 1.5 x 10⁻³ grams per 100 grams of water.

This means that at 25°C, 1.5 x 10⁻³ grams of silver iodide will dissolve in 100 grams of water.

Silver iodide is a sparingly soluble compound, which means that it has low solubility in water. This is due to the ionic nature of silver iodide, which results in strong attractive forces between the ions in the solid form.

As a result, only a small amount of silver iodide can dissolve in water, even at high temperatures. This low solubility has important implications for the use of silver iodide in various applications, including photography and cloud seeding.

The concentration of the NaOH solution is 10.00 g/dm³.

To calculate the concentration in g/dm³ of a solution of NaOH containing 0.25 moles in 1 dm³, we need to know the molar mass of NaOH.

The molar mass of NaOH is calculated as follows:

Na (Sodium) = 22.99 g/mol

O (Oxygen) = 16.00 g/mol

H (Hydrogen) = 1.01 g/mol

Molar mass of NaOH = 22.99 g/mol + 16.00 g/mol + 1.01 g/mol = 40.00 g/mol

Now, we can calculate the concentration (C) using the formula:

C = (moles of solute) / (volume of solution in dm³)

C = 0.25 moles / 1 dm³

C = 0.25 mol/dm³

To convert moles to grams, we can multiply the molar mass by the number of moles:

Concentration in g/dm³ = (0.25 mol/dm³) * (40.00 g/mol)

Concentration in g/dm³ = 10.00 g/dm³

Answer:

A

Explanation:

The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.

The molarity of the sodium sulfate solution is 0.0732 M.

To calculate the molarity of a sodium sulfate  solution that contains 5.2 grams of sodium sulfate diluted to 500 mL, we need to convert the mass of sodium sulfate to moles and divide it by the volume in liters.

First, we calculate the molar mass of sodium sulfate:

Na = 22.99 g/mol (atomic mass of sodium)

S = 32.07 g/mol (atomic mass of sulfur)

O = 16.00 g/mol (atomic mass of oxygen)

Molar mass of Na2SO4 = (2 * 22.99) + 32.07 + (4 * 16.00) = 142.04 g/mol

Next, we convert the mass of sodium sulfate to moles:

moles = mass / molar mass

moles = 5.2 g / 142.04 g/mol = 0.0366 mol

Now, we convert the volume of the solution to liters:

volume (in liters) = 500 mL / 1000 mL/L = 0.5 L

Finally, we calculate the molarity of the solution:

molarity (M) = moles / volume

molarity (M) = 0.0366 mol / 0.5 L = 0.0732 M

Therefore, the molarity of the sodium sulfate solution is 0.0732 M.

The first one is correct.

Explanation: Eh Are you cheating on quiz?

Divers are most at risk when they return to the surface due to the decreased solubility of nitrogen gas in the blood.

In the reaction, the acid is H₂Se, the base is H₂0, the conjugate acid is H₃O⁺, and the conjugate base is SeH.

Increasing the concentration of HA will increase the number of red (H₃O⁺) and blue (A⁻) particles in the solution in chemical equilibrium.

Divers are individuals who dive to great depths in the oceans.

Divers may dive freely without extra gas cylinders or they may dive with gas cylinders containing a mixture of oxygen and nitrogen.

Since gas solubility increases with pressure and decreases with pressure, nitrogen gas bubbles form as divers surface from the depths.

2. Acids are substances that donate protons, whereas bases accept protons.

Conjugate acids are formed when acids donate protons, whereas conjugate bases are formed when bases accept protons.

3. The equation of the reaction is given below:

According to the principle of chemical equilibrium, equilibrium will shift to a position that annuls any constraint placed on the system in equilibrium.

Therefore, increasing the concentration of Ha will result in an increase in H₃O⁺ and A⁻ particles in the solution.

Viscosity is a measure of a fluid's resistance to flow. Plotting viscosity on semi-log coordinates allows for the examination of exponential relationships.

On a semi-log plot of viscosity versus temperature, the slope of the line indicates the activation energy for the viscous flow, and a straight line indicates an Arrhenius relationship.

For water, the viscosity decreases with increasing temperature and does not follow an Arrhenius relationship. Hexane also has a decreasing viscosity with temperature, but deviates significantly from an Arrhenius relationship. On the other hand, 100% glycerol has a relatively constant viscosity with temperature, and is an example of a fluid that follows an Arrhenius relationship.

In general, the viscosity of fluids depends on several factors such as molecular weight, intermolecular forces, and temperature. The deviation from an Arrhenius relationship can indicate more complex relationships between viscosity and temperature, such as the existence of multiple temperature-dependent processes that contribute to the overall viscosity of the fluid.

Boyle's Law, which states that at constant temperature, a gas's pressure and volume are inversely related, can be used to address this issue.

Boyle's Law says that P1V1 = P2V2.

Where: P1 = The gas's initial pressure (in torr)

V1 is the container's initial volume (in millilitres).

P2 stands for the gas's post-volume change pressure (unknown).

V2 is the revised volume of the container (in millilitres).

Let's solve for P2 by entering the provided values into the equation:

P₁ = 757.2 torr

V2 = 132.5 mL V1 = 81.4 mL

P2 = ambiguous

P₁V₁ = P₂V₂

P2 equals 757.2 torr x 81.4 mL x 132.5 mL.

P2 times 132.5 mL = 61702.08 torr * mL

61702.08 torr = P₂ * 132.5

P2 = 132.5 mL / 61702.08 torr

HE: The strongest intermolecular force in the liquid state of HE (helium) is London dispersion forces. Helium is a noble gas with a monatomic structure, which means it consists of individual helium atoms.

London dispersion forces arise from temporary fluctuations in electron density, causing instantaneous dipoles. These temporary dipoles induce additional dipoles in neighboring atoms, resulting in attractive forces between the atoms.

CBr4: The strongest intermolecular force in the liquid state of CBr4 (carbon tetrabromide) is dipole-dipole interaction. CBr4 is a polar molecule due to the unequal distribution of electron density caused by the electronegativity difference between carbon and bromine atoms. The polar bonds in CBr4 result in a net dipole moment, leading to attractive forces between the positive end of one molecule and the negative end of another.

NF3: The strongest intermolecular force in the liquid state of NF3 (nitrogen trifluoride) is also dipole-dipole interaction. NF3 is a polar molecule because of the asymmetrical arrangement of fluorine atoms around the central nitrogen atom. The polar bonds in NF3 give rise to a net dipole moment, causing attractive forces between the positive end of one molecule and the negative end of another.
