Answer:

magnesium carbonate reacts with aqueous acids to release carbon dioxide and water

MgCO3 + 2 HCl → MgCl2 + CO2 + H2O.

How to -

Step 1: Reaction

- Leave the dilute hydrochloric acid in a beaker.

- Add Magnesium carbonate slowly until it is in excess or until no more gas seem to be getting liberated.

Step 2: Filtration

- Filter with filter paper and funnel.

- Filter off the excess magnesium carbonate as magnesium chloride will be in aqueous form (liquid) and will come out with the filtrate. The residue is the excess magnesium carbonate.

Step 3: Crystallization to obtain solid crystals from the filtrate.

- Pour filtrate solution into evaporating dish/basin

- Provide heat using Bunsen burner

- Pour solution into an evaporating basin and heat over a water bath

- Stop heating when crystals start to form

allow water to evaporate until pure crystals remain.

- Dry crystals using absorbent paper or warm oven.

Precautions

- Use personal protective equipment such as gloves, a lab coat and wear eye protection, especially when heating.

- Avoid inhaling unnecessary gases during the whole process.

The atom that has two unpaired electrons is boron (B).

The correct answer is (b) B (boron).

Boron (B) has two unpaired electrons. It has an electron configuration of 1s² 2s² 2p¹. The 2p orbital of boron contains three electrons, with two of them being unpaired.

Let's analyze the other options:

(a) He (helium) has an electron configuration of 1s², and all its electrons are paired, so it does not have any unpaired electrons.

(c) Ca (calcium) has an electron configuration of [Ar] 4s², meaning it has two paired electrons in the 4s orbital. There are no unpaired electrons in calcium.

(d) Se (selenium) has an electron configuration of [Ar] 3d¹⁰ 4s² 4p⁴. All of its electrons are paired, so it does not have any unpaired electrons.

(e) Zn (zinc) has an electron configuration of [Ar] 3d¹⁰ 4s². All of its electrons are paired, so it also does not have any unpaired electrons.

Therefore, the atom that has two unpaired electrons is boron (B).

The hydrogens just on carbons close to the carbonyl group have a shift towards carbonyla triple - negative electronegative atoms of about 200 ppm.

What is the name of the carbonyl group?

A carbon atom is double-bonded to the an oxygen atom to form a carbonyl group, that is a chemically active functional group. Aldehydes and ketones, which are typically joined to another carbon compound, are the simplest carbonyl groups. Many aromatic chemicals have these structures, which contribute to flavor and fragrance.

Which structural subunits make up carbonyls?

Carbonyl-containing functional groups include aldehydes and ketones. The primary distinction is that for carbon to be a member of these functional groups, it must be doubly bonded to other groups in addition to oxygen. A ketone must have a connection between the carbonyl carbon and

There are many chemicals that have associated hazards, so I cannot provide a specific answer without more context. However, the hazard associated with a chemical can vary and may include toxicity, flammability, corrosivity, and more.

The GHS symbol for the hazard and the signal word given on the SDS will depend on the specific hazard associated with the chemical. Regarding the three dyes used in Gatorade, it is unclear which dyes are being referred to, so I cannot provide further information about the banned dye in the EU.
Hi! The chemical in question is the dye called "Brilliant Blue FCF," also known as E133 or Blue 1. This chemical has an associated hazard, which is the potential to cause allergic reactions in some individuals. The GHS (Globally Harmonized System) symbol for this hazard on the SDS (Safety Data Sheet) is the "Exclamation Mark," indicating that it is a less severe health hazard. The signal word given on the SDS for this chemical is "Warning."

The theoretical yield of NH3 is 10.03 g and percent yield is 10.56%

The theoretical yield is obtained from the eequation if reaction.

The equation of the reaction is given below:

moles of reactants and products:

moles of H2 = 1.77/2 = 0.885 moles

moles of N2 = 25.7/28 = 0.918 moles

moles of NH3 = 1.06/17 = 0.062

From the equation of the reaction, H2 is the limiting reactant

3 moles of H2 produces 2 moles of NH3

0.885 moles of H2 will produce 2/3 × 0.918 = 0.59 moles of NH3

Therefore:

theoretical yield = 0.59 × 17

theoreticalyield = 10.03 g of NH3

Percent yield = 1.06/10.03 × 100%

percent yield = 10.56%

Therefore, the theoretical yield is 10.03 g and percent yield is 10.56%.

To find the pressure in kPa we use the conversion

1 atm = 101.3 kPa

If 1 atm = 101.3 kPa

400 atm = 400 × 101.3 = 40520 kPa

Expressing it in standard form we have the final answer as

4.05 × 10⁴ kPa

Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Pressure may also be expressed in terms of standard atmospheric pressure; the atmosphere (atm) is equal to this pressure, and the torr is defined as 1⁄760 of this. Manometric units such as the centimeter of water, millimetre of mercury, and inch of mercury are used to express pressures in terms of the height of column of a particular fluid in a manometer.

If the uncertainty associated with the position of an electron is given as 3.3×10^−11 m, we can find the uncertainty associated with its momentum using the uncertainty principle.

The uncertainty principle states that the product of the uncertainty in position and the uncertainty in momentum must be greater than or equal to ℏ/2, where ℏ is the reduced Planck's constant.

Uncertainty in position (Δx) = 3.3×10^−11 m
Reduced Planck's constant (ℏ) = 1.055×10^−34 kg m^2s

To find the uncertainty in momentum (Δp), we can use the equation:
Δx * Δp ≥ ℏ/2

Substituting the given values, we have:
(3.3×10^−11 m) * Δp ≥ (1.055×10^−34 kg m^2s)/2

Now, let's solve for Δp:
Δp ≥ (1.055×10^−34 kg m^2s)/(2 * 3.3×10^−11 m)
Δp ≥ 1.598×10^−24 kg m/s

Therefore, the uncertainty associated with the momentum of the electron is 1.598×10^−24 kg m/s.

He will arrive at the second city on time

Using the formula for calculating speed expressed as:

Distance = Speed * time

Given the following parameters

Speed = 65km/hr

Time = 3 hours (from noon to 3PM)

Get the distance covered by Isaiah;

Distance = 65 * 3

Distance = 195km > 186km

Since the distance covered by Isaiah is greater than the distance from one city to another city, hence he will arrive at the second city on time

What is Speed?

The speed at which an object's location changes in any direction. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Therefore,

186km at 3:00 the speed limit is 65km/h

He will arrive at the second city on time

The correct answer is:

E. At high temperatures.

The spontaneity of a reaction is determined by the change in Gibbs free energy (ΔG) of the reaction. If ΔG is negative, the reaction is spontaneous, whereas if ΔG is positive, the reaction is non-spontaneous.

The ΔG of a reaction can be calculated using the formula:

ΔG = ΔH - TΔS

where ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.

In this case, the given reaction is exothermic, which means that ΔH is negative. The reaction involves the formation of solid CuO from the reactants, which means that the entropy of the system decreases, and ΔS is negative.

Substituting these values into the equation for ΔG, we get:

ΔG = ΔH - TΔS

Since ΔH is negative and ΔS is negative, the sign of ΔG depends on the value of T. At high temperatures, the TΔS term dominates, and ΔG becomes more negative, making the reaction more spontaneous.

At low temperatures, the ΔH term dominates, and ΔG becomes less negative, making the reaction less spontaneous.

Therefore, the correct answer is:

E. At high temperatures.

Answer: 40.3 L

Explanation:

To calculate the moles :

\(\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}\)

\(\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles\)

\(Sb_2O_3+3C\rightarrow 2Sb+3CO\)  

According to stoichiometry :

1 moles of \(Sb_2O_3\) produces = 3 moles of \(CO\)

Thus 0.600 moles of \(Sb_2O_3\) will produce=\(\frac{3}{1}\times 0.600=1.80moles\)  of \(CO\)

Volume of \(CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L\)
