Explanation:
The reaction between calcium hydroxide and nitric acid is as follows.
Number of reactant atoms are as follows.
- Ca = 1
- O = 4
- H = 3
- N = 1
Number of product atoms are as follows.
- Ca = 1
- O = 4
- H = 2
- N = 3
To balance the given chemical equation, multiply by 2 on reactant side and multiply
by 2 on the product side.
Therefore, the balanced chemical equation will be as follows.
Data:
Q = 402.7 J → releases → Q = - 402.7 J
m = 16.25 g
T initial = 54 ºC
adopting: c = 4.184J/g/°C
ΔT (T final - T initial) = ?
Solving:
Q = m*c*ΔT
-402.7 = 16.25*4.184*ΔT
-402.7 = 67.99*ΔT
If: ΔT (T final - T initial) = ?
