I want to see if i got my answer correct for #1 but I need help on #2
1.A 150g aluminum pan containing 500g of water is heated on a stove for 5 minutes. The temperature goes from 23.5C to 48.9C. How much heat was absorbed. (s for Al is .900j/g C, s for H2O is 4.184 j/g C) I got 3429J AL and 53136.8J H2O heat absorbed?
2. When a 1.000 g sample of the rocket fuel hydrazine, N2H4, is burned in a bomb calorimeter which contains 1200g of water, the temperature rises from 24.62C to 28.16C. If the C for the bomb is 840 J/C
Calculate: q reaction for combustion of a one-gram sample
q reaction for combustion of one mole of hydrazine in the bomb calorimeter
