Quizplus · Accepted Answer

We can use the formula:

q = m*c*ΔT

where q is the amount of heat (in kJ), m is the mass of benzene (in g), c is the specific heat capacity of benzene (in J/g°C), and ΔT is the change in temperature (in °C).

Substituting the given values, we get:

q = (51.8 g) * (1.05 J/g°C) * (52.6 K)
q = 2.86 kJ

Therefore, the amount of heat necessary to raise the temperature of 51.8 g benzene by 52.6 K is 2.86 kJ, which corresponds to choice D.
