Question

study the chemical equation.
na + cl₂ → nacl
is the chemical equation properly balanced?
no. there are two chlorine atoms on the reactant side and only one chlorine atom on the product side.
no. there are two chlorine atoms on the product side and only one chlorine atom on the reactant side.
yes. there is one of each atom on the right side of the equation.
yes. the number and type of atoms on each side of the equation are the same.

Explanation:

First, count the atoms on each side of the equation:

• Reactant side: 1 Na atom, 2 Cl atoms (from $\text{Cl}_2$)
• Product side: 1 Na atom, 1 Cl atom (from $\text{NaCl}$)

A balanced equation has equal numbers of each type of atom on both sides. Here, chlorine atoms are unbalanced (2 on reactant, 1 on product).

Answer:

No. There are two chlorine atoms on the reactant side and only one chlorine atom on the product side.
