1) Which substance will heat up faster: Aluminum (s) specific heat = 0.90 J/g°C Brass (s)…

1) Which substance will heat up faster:

Aluminum (s) specific heat = 0.90 J/g°C

Brass (s) specific heat = 0.380 J/g°C

2)A student mixes 50.0 mL of a 0.100 M AgNO3 solution with 50.0 mL of a 0.100 M HCl solution in a coffee cup calorimeter. Upon mixing the temperature of the resulting solution increases from 22.30°C to 23.11°C. If we assume the resulting solution has a final volume of 100.0 mL and the density and specific heat of the resulting solution are the same as that of water, what is the ΔH of the reaction in kJ/mol AgNO3 reacted?

AgNO3 + HCl → AgCl + HNO3
