a) The combustion of carbon disulfide is given as follow CS2(l)+3O2(g)CO2(g)+2SO2(g) i) From your knowledge, describe heat that associated with chemical or physical change (2 marks) ii) Base on an appropriate law, calculate the enthalpy for the combustion process above. Given the elementary reaction as follow C(s)+O2(g)CO2(g)H=393.5kJ/molS(s)+O2(g)SO2(g)H=296.8kJ/molC(s)+2S(s)CS2()H=+87.9kJ/mol (4 marks) iii) Explain whether the process is exothermic or endothermic
