In a chemical reaction equation.. There must be redox reaction taking palce.. So oxidation and reduction reactions will be happening on both sides of the equation.. You can separate the oxidation and reduction equations in halves. . So there will be one half oxidation equation and the other half reduction equation of the reaction.
Ok well whats the questions

Answer:
Q = 30355.2 J
Explanation:
Given data:
Mass of ice = 120 g
Initial temperature = -5°C
Final temperature = 115°C
Energy required = ?
Solution:
Specific heat capacity of ice is = 2.108 j/g.°C
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
Q = m.c. ΔT
ΔT = T2 -T1
ΔT = 115 - (-5°C)
ΔT = 120 °C
Q = 120 g × 2.108 j/g.°C × 120 °C
Q = 30355.2 J
