Question 1

A 26.2 g piece of copper metal is heated from 21.5°C to 201.6°C.  Calculate the amount of heat absorbed by the metal.  The specific heat of Cu is 0.385 J/g·°C.


Question 2

Calculate the enthalpy of reaction for H2(g) + C2H4(g) → C2H6(g).
         [ΔH°f(C2H4(g)) = 52.3 kJ/mol; ΔH°f(C2H6(g)) = –84.7 kJ/mol]
