Options
Zinc and Hydrogen
Hint
Use the chemical properties of metals to determine the identity of X and G.
Quick Oral Answer
Zinc reacts with both sodium hydroxide and dilute sulphuric acid to produce hydrogen gas, so X is zinc and G is hydrogen.
Analysis & Explanation
The metal X liberates a gas G on treatment with sodium hydroxide and also liberates the same gas G on treatment with dilute sulphuric acid. This means that X is a metal that reacts with both bases and acids to produce the same gas G. From the chemical properties of metals, we can see that zinc reacts with both sodium hydroxide and dilute sulphuric acid to produce hydrogen gas. Therefore, X is zinc and G is hydrogen.
