How many kilo joules of heat are required to the decompost 1.96 mol Nah I 3(s)

Sagot :

Heat required = = 126.42 kJ

Further explanation

Given

1.96 mol NaHCO₃(s)

Required

Heat needed

Solution

Reaction( decomposition of Baking soda (NaHCO₃) :

2NaHCO₃ (s) + 129 kJ ⇒ Na₂CO₃ (s) + H₂O (g) + CO₂ (g)

For 2 mol NaHCO₃ , heat needed = 129 kJ

conversion factor :

[tex]\tt \dfrac{129~kJ}{2~mol}[/tex]

So for 1.96 mol :

= 1.96 mol x (129 kJ/2 mol)

= 126.42 kJ
