How do I solve question 2. e

2. A combustion reaction is the reaction of a carbon-based molecule with oxygen gas to pr carbon dioxide and water. oduce a) b) c) If the density of methane in a standard gas cylinder is 0.226g/cm3, how many moles of Write and balance the reactions for the combustion of methane (CH.) and the combustion of propane (CaHs). How many grams of carbon dioxide are produced when 1.00kg of methane is burned? What about burning 1.00kg of propane? methane can be stored in a 5.00gal tank of methane? What about propane (density of propane is 0.621g/cm3) Burning one mole of methane produces 802kJ of energy and burning one mole of propane produces 2044kJ of energy. How much energy can be produced from each 5.00gal cylinder in part c)? d) A mixture of methane and propane is burned in excess oxygen. The mixture started with a total mass of 3.0g, and when burned completely, produced a mixture of water and carbon dioxide where the moles of water are 1.75 times greater than the moles of carbon dioxide. What is the initial mass of methane in the 3.0g mixture? e) turo s silicon dioxide

Explanation / Answer

Combustion is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fireproduces a flame, and the heat produced can make combustion self-sustaining.

The combustion reaction for methane is as follows:

CH4[g] + 2 O2[g] -> CO2[g] + 2 H2O[g] + energy

For propane:

C3H8 + O2 --> CO2 + H2O
