I really hope this helps you!! :)
I believe the answer is 2
Answer: The specific heat capacity of the sample is and as heat is released in this reaction so it is exothermic in nature.
Explanation:
Given: Mass = 120.4 g
Heat energy released = -7020 J
Initial temperature =
Final temperature =
Formula used is as follows.
where,
q = heat energy
m = mass of substance
C = specific heat capacity
= initial temperature
= final temperature
Substitute the values into above formula as follows.
When heat is released in a process or reaction then it means it is exothermic in nature.
Thus, we can conclude that the specific heat capacity of the sample is and as heat is released in this reaction so it is exothermic in nature.
