Calculate the amount (mass) of acetaldehyde (C2H40, molar mass = 44.0526 g mol-') that causes a
bomb calorimeter with a heat capacity of 12.91 kJ °C 1 to have a temperature increase from 27.8 °C
to 41.7 °C. The ALU for the combustion of acetaldehyde is -1166.9 kJ mol-1

false

because it does not have the potential to be entirely used up

the answer would be a

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
