Question 5 In a chemical reaction between gases, 500cm of oxygen reacts with hydrogen to
form water in a closed container. After the reaction has taken place the container is
left to stand until the temperature and pressure of the gas are the same as they were
before the reaction. There are no unreacted molecules of oxygen or hydrogen
remaining in the container.
a. Write down a balanced chemical equation to represent the reaction
b. Calculate the volume of hydrogen present at the start
c. Calculate the volume of water present after the reaction​
