6.which set of coefficients correctly balances the following chemical mg(oh)2 + hcl imported asset mgcl2 + h2o
a. 1, 1, 1, 1
b. 1, 2, 1, 2
c. 1, 2, 2, 2
d. 2, 4, 2, 4

Option (B) is the correct answer.

Explanation:

A chemical reaction that contains same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example,

Number of atoms on reactant side are as follows.

Mg = 1

O = 2

H = 3

Cl = 1

Number of atoms on product side are as follows.

Mg = 1

O = 1

H = 2

Cl = 2

Therefore, to balance this chemical equation we multiply HCl by 2 on reactant side and multiply by 2 on product side.

Hence, we can conclude that the balanced chemical equation will be as follows.
