these two questions are related and im not looking the answers, but how i would go about setting them up.
Propane, C3H8(g), is used in many instances to produce heat by burning: C3H8(g) + 5O2(g) -->3CO2(g) + 4H2O(g) The standard enthalpy of reaction, , is -2,044 kJ. How many grams of oxygen would be needed to produce 639.0 kJ of heat? is a symbol for the heat of reaction. Enter your answer in scientific notation.
A swimming pool 30.5 meters long, 12.2 meters deep, and 3.0 meters wide is filled with water. The temperature of the water is 23.0 deg C, but the owner of the pool would like the temperature to be 30.6 deg C. How many grams of propane would have to be consumed if all of the heat from the combustion was to be absorbed by the water? Refer to the previous problem. Enter your answer in scientific notation.
