Practice Product in Chemistry

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

A new substance formed as a result of a chemical reaction, appearing on the right side of a chemical equation, with different chemical properties from the original reactants.

What you end up with after the reaction — the new stuff that gets made from the ingredients.

Example 1

easy
Define the term 'product' in a chemical reaction. In the reaction \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2, identify all products.

Example 2

medium
In the reaction \text{Fe}_2\text{O}_3 + 3\text{CO} \rightarrow 2\text{Fe} + 3\text{CO}_2, identify the products and calculate how many moles of each product are formed from 1.5 mol of \text{Fe}_2\text{O}_3.

Example 3

medium
In the reaction 2\text{H}_2 + \text{O}_2 \to 2\text{H}_2\text{O}, identify the reactants and products.

Example 4

medium
When baking soda (\text{NaHCO}_3) reacts with vinegar (acetic acid, \text{CH}_3\text{COOH}), bubbles form. Identify the gas product and explain what evidence indicates a new product has formed.

Example 5

hard
In the Haber process, \text{N}_2 + 3\text{H}_2 \rightleftharpoons 2\text{NH}_3, calculate the mass of ammonia (\text{NH}_3) produced from 56.0 g of nitrogen gas reacting with excess hydrogen. (N = 14.01, H = 1.008\,\text{g/mol})
