GIVEN INFO

LP gas burns according to the following exothermic reaction:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)

ΔH∘rxn= −2044kJ

What mass of LP gas is necessary to heat 1.4 L of water from room temperature (25.0 C) to boiling (100.0 C)? Assume that during heating, 16% of the heat emitted by the LP gas combustion goes to heat the water. The rest is lost as heat to the surroundings.

Answer #1

eases no G C3 Hg + 50% - 3cO2 + 4H20 AHF = -2044 KJ mass of water - 1.4L x density = 14X163 m2 x 1g/mL = 14009: UT = 100€ - 2
