According to the following reaction, how many grams of water are produced in the complete reaction of 29.7 grams of ammonia? 4 N
Gnesinka [82]

<u>Answer:</u> The mass of water produced in the reaction is 47.25 grams.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}      .....(1)

Given mass of ammonia = 29.7 g

Molar mass of ammonia = 17 g/mol

Putting values in equation 1, we get:

\text{Moles of ammonia}=\frac{29.7g}{17g/mol}=1.75mol

The given chemical reaction follows:

4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+6H_2O(g)

By stoichiometry of the reaction:

4 moles of ammonia produces 6 moles of water.

So, 1.75 moles of ammonia will produce = \frac{6}{4}\times 1.75=2.625mol of water.

Now, calculating the mass of water by using equation 1, we get:

Molar mass of water = 18 g/mol

Moles of water = 2.625 moles

Putting values in equation 1, we get:

2.625mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=47.25g

Hence, the mass of water produced in the reaction is 47.25 grams.

A company produces a colorless vinegar that is 5.0% HC2H3O2 in water. Using thymol blue as an indicator, a student titrates a 15
Nataly_w [17]

The negative ion in aqueous sodium hydroxide, NaOH(aq) is hydroxide ion, OH-.

<h3>What is a neutralization reaction?</h3>

A neutralization reaction is a reaction between an acid and a base to form salt and water only.

The reaction between vinegar and NaOH is a neutralization reaction which produces a salt and water only.

NaOH is composed of a positive sodium ion, Na+ and a negative hydroxide ion, OH-

Therefore, the negative ion in the NaOH(aq) used in this titration is hydroxide ion, OH-.
