Magnesium reacts with steam to form magnesium oxide and a gas.

(a) Name the gas formed during the reaction.
(b) Complete the above diagram to show how the gas could be collected.
(c) Describe a test for the gas and state the result you would expect to obtain.

Text Solution

Verified by Experts

(a) Hydrogen gas
`underset("Magnesium")(Mg_(s)) + underset("Steam")(H_(2)O_((g))) to underset("Magnesium oxide")(MgO_((s))) + underset("Hydrogen")(H_(2(g)))`
(b) `H_(2)` gas is collected by downward displacement of water in the inverted test tube.

(c ) bring a burning match stick near the `H_(2)` gas evolved. It burns with a pop sound.
