Question

This equation shows the neutralization of sodium hydroxide and hydrochloric acid:

NaOH + HCl → H2O + NaCl

The reactant side of the chemical equation has (1/2/3/4) atom(s) each of sodium, oxygen, and chlorine. The reactant side also has (1/2/3/4) hydrogen atom(s). Count the numbers and kinds of atoms on the product side of the equation. The numbers and kinds of atoms on both sides of the chemical equation are (the same/not the same). So, this chemical equation is (balanced/not balanced) .

Answer 1

There are the same amount on both sides. Therefore, it is balanced. On both sides there is 1 Na atom, 1 O atom, 2 H atoms, and 1 Cl atom.

Answer 2

Answer:

The reactant side of the chemical equation has  

1

atom(s) each of sodium, oxygen, and chlorine. The reactant side also has  

2

hydrogen atom(s). Count the numbers and kinds of atoms on the product side of the equation. The numbers and kinds of atoms on both sides of the chemical equation are  

the same

. So, this chemical equation is  

balanced

.
