7. When a mixture of gases X and Y is compressed to 340 atm pressure and thenpassed over a catalyst consisting of a mixture of Zinc oxide and Chromiurm oxide(heated to a temperature of 300°C), then an organic compound Z having themolecular formula CH4O is formed. X is a highly poisonous gas which is formed inappreciable amounts when a fuel burns in a limited supply of air ; Y is a gas whichcan be made by the action of a dilute acid on an active metal; and Z is a liquidorganic compound whích can react with sodium metal to produce Hydrogen gas.(a) What are X, Y and Z?(b) Write a balanced chemical equation of the reaction which takes place when X anY combine to form Z. Indicate the conditions under which the reaction occurs.
