Balanced chemical equations only show formulae, not names. A balancing number, written in normal script, multiplies all the atoms in the substance next to it.
Answer:
See below
Explanation:
Q = m c T c = specific heat T = temp change Q = heat joules
32 = 4 c 40 <u> c = .2 J/g-C</u>
314 to 344 k is a change of 30 K
Q = m c T
= 4 * .2 * 30 = <u>24 Joules </u>
