Question

1. na + cl₂ → __ na⁺¹cl⁻¹

Explanation:

Step1: Balance chlorine atoms

There are 2 chlorine atoms in \(Cl_2\). To balance chlorine, put 2 in front of \(NaCl\).

$$\text{Na}+\text{Cl}_2 ightarrow 2\text{NaCl}$$

Step2: Balance sodium atoms

There are 2 sodium atoms in \(2NaCl\). So put 2 in front of \(Na\).

$$2\text{Na}+\text{Cl}_2 ightarrow 2\text{NaCl}$$

Answer:

\(2\text{Na}+\text{Cl}_2
ightarrow 2\text{NaCl}\)
