1. A chemical engineer studying the properties of fuels placed 1.500 g of a hydrocarbon in the bomb of a calorimeter and filled it with O2 gas. The bomb was immersed in 2.500 L of water and the reaction initiated. The water temperature rose from 20.00°C to 23.55°C. If the calorimeter (excluding the water) had a heat capacity of 403.0 J/K, what was the heat of combustion (total heat from the reaction) per gram of the fuel?
2. Classify the following mixtures as homogeneous or heterogeneous. Explain your reasoning.
a. lemon juice
b. tap water
c. house paint
d. blood
