The initial temperature of the water in a constant-pressure calorimeter is 14°C. A reaction takes place in the calorimeter, and the temperature rises
to 87°C. The calorimeter contains 254 g of water, which has a specific heat
of 4.18 J/(g.°C). Calculate the enthalpy change during this reaction. *

The enthalpy change during this reaction is 77505.56 J.

Explanation:

Given: ,        

Mass = 254 g,       Specific heat =

Formula used to calculate the enthalpy change is as follows.

where,

q = enthalpy change

m = mass of substance

C = specific heat capacity

= initial temperature

= final temperature

Substitute the values into above formula as follows.

Thus, we can conclude that the enthalpy change during this reaction is 77505.56 J.

answer; /// i do believe that the correct answer is (c)nuclear bond

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
