How do you balance this equation: ?NaHCO_3 → ?NaOH + ?CO_2?

May 24, 2017

Explanation:

Na is sodium,
H is hydrogen,
C is carbon and
O is oxygen.

Sodium is balanced, there's 1 on each side.
Oxygen is also balanced, there's 3 on each side. (For the RHS, add up the O in $N a O H$ and $C {O}_{2}$.
Hydrogen is balanced, there's 1 on each side.
Carbon is balanced, there's 1 on each side.

Explanation:

$N a H C {O}_{3} \to N a O H + C {O}_{2}$

If you compute reactants and products, check it:

Reactants: $1 N a , 1 H , 1 C , \mathmr{and} 3 O$
Products: $1 N a , 1 H , C , \mathmr{and} \left(1 + 2\right) O$

This reaction is a balanced reaction:

$N a H C {O}_{3} \to N a O H + C {O}_{2}$
