Question

Write the balanced chemical equations for the following word equations:

$\left(e\right).\text{Sodium}+\text{chlorine}\to \text{Sodium chloride}$

Answer 1

The skeletal equation is:
$Na+C{l}_2\to NaCl$

Count the number of atoms of each element on either side of the reaction

• Number of atoms on reactant side:

$Na=1,Cl=2$

• Number of atoms on the product side:

$Na=1,Cl=1$

• To equalize $Cl$, multiply $NaCl$ by $2$.

$Na+C{l}_2\to 2NaCl$

• To equalize $Na$, multiply $Na$ by $2$.

$2Na+C{l}_2\to 2NaCl$

Therefore, the balanced chemical equation for the reaction is:
$2Na+C{l}_2\to 2NaCl$
