This is the specific heat capacity of aluminum metal given the scenario below.
A 35.0-gram sample of aluminum metal was heated to 88.5 ∘C and then quickly placed into a calorimeter containing 100.0 grams of water at 22.0 ∘C. The final temperature of both the metal and the water was 25.6 ∘C.
cwater = 4.18 J/g ∘C
0.684 J/g ∘C

Given the following reactions and their enthalpy changes:
C (s) + O2 (g) → CO2 (g) ΔH= -393.5 kJ/mol
H2 (g)+ 1/2 O2 (g)→ H2O (l) ΔH=−241.8 kJ/mol
C (s)+ 2 H2 (g)→ CH4 (g) ΔH=−74.8 kJ/mol
Use Hess's Law to calculate the enthalpy change for the following reaction:
CH4 (g)+ 2 O2 (g)→ CO2 (g)+2 H2O (l)
-802.3 kJ/mol
