Volume-Volume Problems

Identify the following chemical equations by type.

1. If an electric discharge produces 500 cm³ of ozone (O₃), how many cm³ of oxygen (O₂) are required?

3O_2(g) ---> 2O_3(g)

2. When 2.75 dm³ of react with an excess of glucose, according to the reaction below, what volume of carbon dioxide will be produced?

6O_2(g) + C₆H₁₂O_6(s) ---> 6H₂O_(g) + 6CO_2(g)

3. If an excess of nitrogen gas reacts with 25.0 L of hydrogen gas, according to the reaction below, how many L of ammonia will be produced?

N_2(g) + 3H_2(g) ---> 2NH_3(g)

4. How many cm3 of oxygen would be required to react completely with 250.0 cm3 of hydrogen gas according to the reaction below?

2H_2(g) + O_2(g) ---> 2H₂O_(g)
