Ethylene C2H4 produces a large amount of heat when combined with pure oxygen.Assuming no other competing reactions and using the following balanced thermochemical equation:2C2H4(g) +6O2(g) ---->4CO2(g) + 4H2O(g) deltaH = - 1200KJ
Completely calculate the amount of heat that is produced when containers with 200g of acetylene and 600 g of oxygen are allowed to react
A mixture of methane and air is capable of being ignited only if the mole percent of methane is between 5% and 15%. A mixture containing 9.0 mole % methane in air flowing at a rate of 700.kg/h is to be diluted with pure air to reduce the methane c..
Which substance would you expect to have a higher melting temperature, ethane, made with 2 carbon atoms (two methanes stuck together), or octane with carbon atoms (eight methanes stuck together)?
A tank is being filled through a valve by an ideal gas where the following applies: H=30*T(K) in J/mol for gas, R=8.314 in J/mol/K, H=40 T(K) for the liquid in J/mol (gas as liquid, different reference point than gas)
lithium is the least dense metal known (density: 0.53 g/cm^3) what is the volume occupied by 8.00 x10^3g of lithium.
At 100 ?C the vapor pressures of hexane and octane are 1836 and 354 torr, respectively. A certain liquid mixture of these two compounds has a vapor pressure of 666 torr at 100 ?C. Find the mole fractions in the liquid mixture and in the vapor phas..
