Answer:
d. 6.28 kJ.
Explanation:
step by step explanation
Q=Q1+Q2
Q=mc(t1-t0) + mlv
Q=total heat generated
Q1=quantity of heat required to raise 25.0°C to 76.8°C to liquid state
Q2= quantity of heat required to convert ccl at 76.8°C to its gaseous state
M=mass of ccl4
C=specific heat capacity of ccl4(0.866j/gk)
T1=final temperature 76.8°C
T0=initial temperature 25.0 °C
LV=latent heat of vapourization (1.959 *10^2j/g)
Q=25*0.866 *(76.8-25) +25*1.959*10^2
Q=6.28kj
