How many calories are absorbed by a copper spoon with a mass of 200 grams as it changes from 28°c to 33°c? (note, this could be physics, but i have integrated physics & chemistry.)

a. 0.00027
b. 3
c. 90
d. 13,000

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m
