A 10.151 g sample of window cleaner containing ammonia was diluted with 39.466 mL of water. Then 4.373 g of solution was titrated with 14.22 mL of 0.1063 M HCl to reach a bromocresol green end point. Find the weight percent of NH3 (FM 17.031) in the cleaner.

Answers

Answer:

2.878 (w/w)%

Explanation:

The reaction of NH3 with HCl is:

NH3 + HCl → NH4Cl

That means 1 mole of ammonia reacts per mole of HCl. The moles of HCl that reacts = Moles of ammonia are:

14.22mL = 0.01422L * (0.1063mol HCl / L) = 0.001512 moles HCl = Moles ammonia

In mass:

0.001512 moles NH3 * (17.031g / mol) = 0.02574g of NH3 in the solution.

The concentration in weight percent of the diluted solution is:

0.02574g of NH3 / 4.373g * 100 = 0.5887 (w/w)%

This is the concentration of the diluted solution that was diluted from 10.151g to 10.151g + 39.466g = 49.617g

-Assuming density of water = 1g/mL-

The solution was diluted:

49.617g / 10.151g = 4.888 times.

That means the concentration of NH3 in the original cleaner is:

0.5887 (w/w)% * 4.888 =

2.878 (w/w)%

Write a balanced equation for each of the acid-base reaction given below.a. Aqueous sulfuric acid with aqueous potassium hydroxide.

Answers

Answer:

H2SO4 + 2KOH => K2SO4 + 2H2O

Explanation:

The acid-base reaction is a type of chemical reaction that involves the exchange of hydrogen ions.

The acid-base reaction between aqueous sulfuric acid ( H2SO4 ) and aqueous potassium hydroxide (KOH) is a neutralization reaction that results in potassium sulfate and water.

sulfuric acid + potassium hydroxide => potassium sulfate + water

So, the balanced equation for this reaction is as follows:

                  H2SO4 + 2KOH => K2SO4 + 2H2O

Hence, the correct answer is "H2SO4 + 2KOH => K2SO4 + 2H2O".

In chemical reactions, what does the law of conservation of mass mean?
Group of answer choices

Matter is not created nor destroyed.

The total mass of the products is greater than the total mass of the reactants.

The total mass of the reactants is less that the total mass of the products.

Matter is not changed.

Answers

Answer

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

What are valence electrons? How do you quickly determine the number of valence electrons an
atom has?

Answers

Answer:

Electrons that arent electrons

Explanation:

I teach chem

Answer:

Valence electrons are the electrons found in the highest and main energy level of the atom, being these responsible for the interaction between atoms of different species or between atoms of the same species. You can quickly determine these by looking at a periodic table like this one... Which is where the roman numbers come in and show the valence electrons.

Air masses that form over large bodies of water are moist. What process determines the amount of moisture in an air mass?

Answers

Answer:

I don't know if this is right but try it. The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity. This amount of space in air that can hold water changes depending on the temperature and pressure.
