22.8 g of cu from

a.

b.

c.
d.
e.

7.51 kJ

Explanation:

This question is asking for an amount of heat so you need the answer to be in terms of Joules (J or kJ). The equation to solve this problem is:

Q = mcΔT where Q is heat, m is the mass of copper, c is the specific heat, and ΔT is the change in temperature.

Given:

mass m = 22.8 g

specific heat, c = 0.385 J/g.°C

ΔT = 875°C - 20.0°C

Q = (22.8g)(0.385 J/g C)(875°C - 20.0°C) = 7510 J or 7.51 kJ
