Answer 1

Answer:

(i) hydrogen

Explanation:

(i) This test is most commonly used to identify hydrogen, which extinguishes with a distinctive 'squeaky pop' sound. Hydrogen is easily ignited, as it is flammable over a wide range of concentrations in air, making this test quite robust. If the gas is non-flammable, the burning splint will be extinguished.
