Chemistry

Calculate the enthalpy of reaction for the following reactionusing Hess's Law and the equations provided below.

Target Reaction: Sr(s)+C(graphite)+1 1/2 O2(g) ----->SrCO3(s) H(degrees)=?

C(Graphite)+ O2(g)-----> CO2(g)H(degrees)= -349kJ

Sr(s)+ 1/2 O2(G)-------> SrO(s) H(degrees)=-592kJ

SrO(s)+CO2(g)-------> SrCo3(s)H(degrees)= -234kJ
