Choose the correct coefficients for the following reaction:

Mg(OH)2 + H2(SO4) → Mg(SO4) + H2O

a
1, 1, 1, 2

b
Balanced

c
2, 2, 2, 1

d
2, 2, 1, 2

Hey there!

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + H₂O

Balance O. (not including SO₄)

2 on the left, 1 on the right. Add a coefficient of 2 in front of H₂O.

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + 2H₂O

Balance H.

4 on the left, 4 on the right. Already balanced.

Balance SO₄. (polyatomic ion)

1 on the left, 1 on the right. Already balanced.

Balance Mg.

1 on the left, 1 on the right. Already balanced.  

Our final balanced equation:

Mg(OH)₂ + H₂(SO₄) → Mg(SO₄) + 2H₂O

So your answer is a. 1, 1, 1, 2.

Hope this helps!

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
