Question

A metal M reacts with an acid according to the given equation M+H(2+) -----> M(3+) + H2

Answer 1

magnisum can br react with hitrogen.

Answer 2

Answer: The balanced chemical equation is given below.

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state gets increased.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state gets reduced.

From the given equation, metal is loosing electrons and thus is getting oxidized and hydrogen is getting gaining electrons, thus it is getting reduced.

Oxidation half-reaction:  $M\rightarrow M^{3+}+3e^-$        ×  2

Reduction half-reaction:  $2H^++2e^-\rightarrow H_2$       ×  3

The net reaction for the above two reactions become:

$2M+6H^+\rightarrow 2M^{3+}+3H_2$

Hence, the balanced chemical equation is given above.
