Your Question
A bomb calorimeter has a heat capacity of 675 J/°C and contains 925 g of water. If the combustion of 0.500 mole of a hydrocarbon increases the temperature of the calorimeter from 24.26°C to 53.88°C, determine the enthalpy change per mole of hydrocarbon. The specific
heat of water = 4.184 J g-1 °C-1.
Just the answer
What is the enthalpy change when 175 g of C3H8 are burned in excess O2?
C3H8(g) + 5 O2(g) ® 3 CO2(g) + 4 H2O(l) DH° = -2220 kJ
just the answer
A sample of water containing 2.00 moles is initially at 30.0°C. If the sample absorbs 2.00 kJ of heat, what is the final temperature of the water? (specific heat of water = 4.184 J g-1 °C-1)
