Question

Silvery white granulated metal when reacted with an acid (at room temperature) and a base (on warming) separately produce a gas,which burns with a pop sound. The gas formed when bubbled through a soap solution form soap bubbles, which rises up in the air.Name the silvery white metal and the gas evolved.​

Answer 1

Answer:

The greyish metal is zinc and the evolved gas is hydrogen

Explanation:

hope you understand

Answer 2

Answer:

Sivery White Metal - Magnesium (Mg)

Gas evolved - Hydrogen (H2)

Explanation:

When magnesium reacts with an acid or base it produces Hydrogen gas which produces a pop sound on burning.

The equations are as follows:

Mg + 2HCl → MgCl2 + H2 (with an acid)

2Mg + 2NaOH → 2MgO + 2Na + H2 (with an base)
