Answer:
The final temperature is 31.95° C.
Explanation:
Given that,
Initial temperature of a sample of chloroform, 
Mass of chloroform, m = 150 g
It absorbs 1 kJ of heat, Q = 10³ J
The specific heat of chloroform, c = 00.96 J/gºC
We need to find the final temperature. The heat absorbed by an object in terms of specific heat is given by :
So, the final temperature is 31.95° C.
Oxidation refers to a change in electrons (In this case, loss of electrons). It has no impact on the number of neutrons, or for that matter on any sub-atomic particles in the nucleus. So the number of neutrons (3) remains the same
