Answer:
The heat of reaction -1.9 kilo Joules.
Explanation:
Volume of the hydrogen peroxide solution = 50.0 mL
Volume of the ferric nitrate solution = 10.0 mL
Total volume of the solution = 50.0 mL + 10.0 mL = 60.0 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL
Heat capacity of the mixture = c = 4.18 J/g°C
Change in temperature of the mixture = ΔT = 7.47°C
Heat absorbed by the mixture = Q
Heat release due to reaction = -Q'
-Q' =Q (law of conservation of enrage)
Q'= -Q = -1.9 kJ
The heat of reaction -1.9 kilo Joules.
