How many kilo joules of heat are required to the decompost 1.96 mol Nah I 3(s)
1 answer:
Heat required = = 126.42 kJ
<h3>Further explanation</h3>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 :
So for 1.96 mol :
= 1.96 mol x (129 kJ/2 mol)
= 126.42 kJ

0.3268 moles of PC15 can be produced from 58.0 g of Cl₂ (and excess
P4)
<h3>How to calculate moles?</h3>The balanced chemical equation is
The mass of clorine is m() = 58.0 g
The amount of clorine is n() = m(
)/M(
) = 58/70.906 = 0.817 mol
The stoichiometric reaction,shows that
10 moles of yield 4 moles of
;
0.817 of yield x moles of
n() = 4*0.817/10 = 0.3268 mol
