What is the element produced when magnesium metal reacts with hydrochloric acid?

Answer 1

Reaction:

Mg(s) + 2HCl(aq) ----> MgCl2(aq) + H2(g)

The products formed are Hydrogen gas H2(g), resulting in fizzing as the gas forms bubbles and is released,

and Magnesium Chloride MgCl2(aq) compound.

The compound (salt) produced is MgCl2 and the element produced is Hydrogen.

Answer 2

The element produced is HYDROGEN gas.

Remember the general acid reaction equations.

Acid + Metal = Salt + Hydrogen

Acid + Alkali = Salt +Water

Acid + Base = Salt +Water

Acid + Carbonate = Salt +Water + Carbon Dioxide

In this case use the first eq'n

Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g) .

Answer 3

When magnesium metal reacts with hydrochloric acid, magnesium chloride and hydrogen gas are produced.
