The heat of combustion of methane is -890 kj per mole. How much heat will be produced in the combustion of 6.25 mol of methane?
-890 kJ / 1 mole
? kJ / 6.25 moles
-5562.5 kJ
To find out how much heat will be produced in the combustion of 6.25 moles of methane, you can use the concept of stoichiometry and the given heat of combustion value.
First, determine the amount of heat produced per mole of methane. Since the heat of combustion of methane is -890 kJ/mol, it means that for every mole of methane burned, 890 kJ of heat is released.
Next, calculate the heat produced for 6.25 moles of methane. Multiply the number of moles of methane (6.25 mol) by the heat of combustion per mole (-890 kJ/mol):
Heat produced = 6.25 mol × -890 kJ/mol
Calculating this equation will give you the amount of heat produced in the combustion of 6.25 moles of methane.
