Propane gas is used to heat a tank of water. If the tank contains 200 L of water, what mass of propane will be required to raise its temperature from 20 degrees C to 65 degrees C. The heat of combustion for propane is -2220 kJ/mol.

Here are the steps (at the last of the post) Stoichiometry-I have the basic strategy, but am still stuck on how to do them.example...propane burns in oxygen according to the following reaction C3H8 + O2 produces CO2 + H20 a. How many moles of CO2 are formed when 2.8 g of ...

You may use a shortcut to do these stoichiometry problems when only gases are involved. C3H8 + 5O2 ==> 3CO2 + 4H2O I do these in two parts. 1. How much CO2 is produced if I have 10L C3H8 and all the oxygen I need? That is 10L propane x (3 moles CO2/1 L C3H8) = 10 x 3/1 = 30...

Chemistry
When using a limited quantity of oxygen to react with propane (C3H8), this will result in producing carbon monoxide (CO) and carbon dioxide (CO2) gases. If 25% of 128 g of propane used in such process is converted into CO and the rest into CO2, calculate: 1- the volume of ...

Many portable gas heaters and grills use propane, C3H8(g). Using enthalpies of formation, calculate the quantity of heat produced when 15.0g of propane is completely combusted in air under standard conditions. Assume that liquid water is forming.

Yes. I wondered if confuded was a new word I should learn. I think the problem is a stoichiometry problem IF you know the heat of combustion. Do you know that? If so, then C3H8 + 5O2 ==> 3CO2 + 4H2O So it takes 44 g C3H8 to generate ??kJ (the heat of combustion generally ...

This is an example of a combustion reaction involving a hydrocarbon (in this case propane) reacting with oxygen. The products of such reactions are almost always water and carbon dioxide. C3H8(g) + O2(g) → H2O + CO2 First balance the number of Carbons on both sides. ...
