Will give ! ❤ consider the half reactions below for a chemical reaction. what is the overall equation for this chemical reaction? first image: problem second image: a third image: b fourth image: c fifth image: d

A. Mg(s) + 2H^(+)(aq) → Mg^(2+)(aq) + H_2(g)

Step 1. Add the two equations and get

Mg(s) + 2H^(+)(aq) + 2e^(-) → Mg^(2+)(aq) + H_2(g) + 2e^(-)

Step 2. Cancel species that appear on each side of the arrow.

The electrons cancel and you get

A. Mg(s) + 2H^(+)(aq) → Mg^(2+)(aq) + H_2(g)

“B.” is wrong because it contains electrons.

“C.” is wrong because it has reversed reactants and products.

“D.” is wrong because there is no H in any of the half-reactions

i can ! i just need to know what the paragraph is! : p

the answer is minerals.
