The compound B5H9 was once proposed as a rocket fuel because it has a high heat of combustion. In a combustion experiment, a scientist observes that 1.00 g of B5H9 burned in excess oxygen in a calorimeter raises the temperature of 800 g of water from 24.0 degrees Celcius to 44.3 degrees Celcius. How much heat is generated in the reaction?

1 answer

q = heat generated = mass H2O x specific heat H2O x (Tfinal-Tinitial)
Do you know specific heat H2O is 4.184 J/g*C
You have Tf and Ti
