The heat of a reaction may be found with the equation q=mc deltaT.

Q=mcΔT Q = mc Δ T , where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase. The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.

Explanation:

0.59 ± 0.081 = (0.671, 0.509)  
Explanation: 
The sample proportion, p = 118/200 = 0.59 
The test statistic at 98% confidence interval is given by : 
p + z*Sqrt(p(1-p)/n) ; p - z*Sqrt(p(1-p)/n) 
z at 98% C.I. is 2.33 
Therefore, 0.59 + 2.33 * sqrt(0.59*(1-0.59)/200) and 0.59 + 2.33 * sqrt(0.59*
(1-0.59)/200)
 =0.59 + 0.081 and 0.59 - 0.081
 =0.671, 0.509
