Answer:

MnSO₄ → MnO+SO₃ is a decomposition reaction.

Explanation:

In a decomposition reaction, a single substance breaks down or breaks down, producing two or more different substances. In other words, decomposition reactions are those that form two or more substances from a compound. In this reaction the atoms that form a compound are separated to give the products according to the formula:

AB → A + B

This type of reactions can occur spontaneously or caused by certain external factors, such as heat, that promote the breakdown of the molecule into simpler substances.

There are 3 types of decomposition reactions, depending on the external factor that causes the reaction:

If the decomposition is caused by a catalyst, it is called catalysis.
If the decomposition occurs by the application of heat it is called thermal decomposition.
If the decomposition is produced by the application of electric current, it is called electrolytic decomposition or electrolysis.

Then MnSO₄ → MnO+SO₃ is a decomposition reaction.

A sample of gas (1.9 mol) is in a flask at 21 °C and 697 mmHg. The flask is opened and more gas is added to the flask. The new p

mariarad [96]

Answer:

The new moles of the gas in the flask is 2.13 moles.

Explanation:

Given;

number of moles of gas, n = 1.9 mol

temperature of the gas, T = 21 °C = 21 + 273 = 294 K

pressure of gas, P = 697 mmHg

volume of gas, V = ?

Apply ideal gas law;

PV = nRT

Where;

R is gas constant, = 62.363 mmHg.L / mol. K

V = nRT / P

V = (1.9 x 62.363 x 294) / 697

V = 49.98 L

New pressure of the gas, P = 795 mmHg

New temperature of the gas, T = 26 °C = 273 + 26 = 299 K

New moles of the gas, n = ?

Volume of the gas is constant because volume of the flask is the same when more gas was added.

n = PV / RT

n = (795 x 49.98) / (62.363 x 299)

n = 2.13 moles

Therefore, the new moles of the gas in the flask is 2.13 moles.

Nina [5.8K]

Answer:

The mass percent of NaOCl = 3.48%

Explanation:

The mass percent of sodium hypochlorite in household bleach is determined by an oxidation-reduction titration with sodium thiosulfate.

In this reaction, the iodide is oxidized to form aqueous iodine, I₂ (aq) Iodine is not very soluble in water but in the presence of iodide ions, it immediately converts to the tri iodide ion (I₃⁻ ) which is soluble and forms a deep yellow solution.

RideAnS [48]

Answer:

1) Favor formation of reactant

2) Favor formation of product

3) Favor formation of product

4) Favor formation of product

5) Favor formation of product

Explanation:

The reaction is $AgBr(s)--->Ag^{+}(aq)+Br^{-}(aq)$

The reaction is endothermic

1. Adding hydrobromic acid (HBr)

It will increase the amount of bromide ion. Bromide ion is one of the product so it will favor formation of reactant.

2. Lowering the concentration of bromide (Br-) ions

As we are decreasing the the concentration of product it will favor formation of more products

3. Heating the concentrations

If we are heating the mixture, it will increase the temperature and it will favor endothermic reaction. Thus will favor formation of product.

4. Adding solid silver bromide (AgBr)

If we are adding silver bromide it means we are increasing the concentration of reactant, it will favor formation of products

5. Removing silver (Ag+) ions

Removing silver ions means we are decreasing the concentration of product thus it will favor formation of products.

If the coefficient 2 is placed in front of the product tetraiodine nonaoxide (I4O9), then, how many atoms of each element must b

Svetlanka [38]

The coefficient of any substance in a chemical equation indicates the number of moles of that substance which are present. We can see from its chemical formula that tetraiodine nonaoxide contains four iodine atoms and nine oxygen atoms. If the coefficient is two, then the total iodine atoms will be eight and the total oxygen atoms will be 18. Because the law of conservation of mass holds, an equal amount must be accounted for on the other side of the chemical equation. Therefore, the first option is correct.
