Looking at the chemical reactions in each answer choice, please choose the chemical reaction that is balanced. A. Pb(OH)2 + 2HCl → 2H2O + PbCl2 B. 2Pb(OH)2 + HCl → H2O + 2PbCl2

A. Pb(OH)2 + 2HCl → 2H2O + PbCl2

Explanation:

In a balanced reaction, the amount of different atoms in the products must be equal to number of atoms in reactants. With the equations of the problem:

A. Pb(OH)2 + 2HCl → 2H2O + PbCl2

There is 1 atom of Pb in reactants and products.

2 atoms of O in both sides.

4 atoms of H

And 2 atoms of Cl

That means this reaction is balanced

B. 2Pb(OH)2 + HCl → H2O + 2PbCl2

2 atoms of Pb

4 atoms of O in reactants but just 1 in products.

As the amount of oxygen is not equal for reactants and products we can say the reaction is unbalanced.

And right choice is A.

have a great day because if you dont you and i will be sad
