Question

Name the reactants and products in the following skeletal equation and balance them.
(i) $Na+C{l}_2\to NaCl$

Answer 1

The skeletal equation is: $Na+C{l}_2\to NaCl$
Reactants are sodium and chlorine, the product is sodium chloride

• Count the number of atoms of each element.
• Multiply the NaCl on product side by $2$,

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

• Multiply the Na on reactant side by $2$,

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

Hence, the balanced chemical equation is $2Na+C{l}_2\to 2NaCl$
