🤓 Based on our data, we think this question is relevant for Professor Culbertson's class at K- STATE.
We’re being asked to calculate the amount of energy released when 23.6 g of mercury at 25.00 ˚C is converted to a solid at its melting point (234.32 K or –38.68 ˚C).
Note that cooling and freezing is an exothermic process, which means q is negative (–).
There are two heats involved in this problem:
1. q1 which is the heat in cooling 23.6 g of Hg from 25 ˚C to –38.68 ˚C
2. q2 which is the heat in freezing 23.6 g of Hg at –38.68 ˚C
We need to solve for each heat individually then add them together to get the final answer.
Calculate the heat energy (kJ) released when 23.6 g of liquid mercury at 25.00°C is converted to solid mercury at its melting point.
