Question

Write balanced chemical equation for the following word equation:

Sodium $+$ Chlorine $\to$ Sodium chloride

Accepted Answer

The word equation is

Sodium $+$ Chlorine $\to$ Sodium chloride

Formulae for the reactants are $Na$ and ${Cl}_{2}$ while, for the product the formula is $NaCl$ .

Therefore, the skeletal equation is $Na + {Cl}_{2} \to NaCl$

Equation is balanced by hit and trial method. Count the number of atoms of various elements on both sides of the equation and make them equal by multiplying formulae by suitable numbers if necessary. The number of atoms of each element is same on both side. Therefore, the balanced equation for the given word equation is

$2 Na + {Cl}_{2} \to 2 NaCl$

Write balanced chemical equation for the following word equation:

Sodium $+$ Chlorine $\to$ Sodium chloride
