The specific heats of water and iron are 4.184 and 0.444 J/g°C, respectively. When
equal masses of water and iron both absorb the same amount of heat, the
temperature increase of the water will be 5.42 times greater than that of the iron.
Explain your answer:
T/F
A 100. mL sample of 0.200 M aqueous hydrochloric acid is added to 100. mL of 0.200 M
aqueous ammonia in a calorimeter whose heat capacity (excluding any water) is 480. J/K. The
following reaction occurs when the two solutions are mixed:
HCl(aq) + NH3(aq) → NH4Cl(aq)
The temperature increase is 2.34°C. Calculate AH per mole of HCI and NH3 reacted.
A. 154 kJ/mol
B. 1.96 kJ/mol
C. 485 kJ/mol
D. 1.96 kJ/mol
E.154 kJ/mol
