Write balanced equations for the combustion of the hydrocarbons in Problem 5.76 in (a) a slightly limited supply of oxygen and (b) a very limited supply of oxygen. Write balanced chemical equations for the complete combustion (in the presence of excess oxygen) of the following: (a) C 12 H 26 (a component of kerosene), (b) C 18 H 36 (a component of diesel fuel), (c) C 7 H 8 (toluene, a raw material in the production of the explosive TNT).

1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°?
To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide.
kindly show me how to solve this long problem. Thanks
