A) A silver block, initially at 55.4 ∘C, is submerged into 100.0 g of water at 25.3 ∘C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 26.8 ∘C. What is the mass of the silver block?
B) Charcoal is primarily carbon. What mass of CO2 is produced if you burn enough carbon (in the form of charcoal) to produce 4.50×102kJ of heat? The balanced chemical equation is as follows: C(s)+O2(g)→CO2(g),ΔH∘rxn=−393.5kJ
