Question

How many moles of CO2 are produced when 1 mole wax C31H64 is burned?

31 32 64 or 47

Answer 1

31 moles.

Step-by-step explanation:

The products of combustion are CO2 and H2O.

C31H64 + 47O2 ---> 31CO2 + 32H2O

Answer 2

31 moles

Step-by-step explanation:

The balanced combustion reaction of the wax,
`C_(31)H_(64)` is shown below as:

`C_(31)H_(64)+47O_2\rightarrow 31CO_2+32H_2O`

As seen from the reaction,

1 mole of wax,
`C_(31)H_(64)` on combustion produces 31 moles of carbon dioxide,
`CO_2`

Hence, moles of
`CO_2` when 1 mole of wax,
`C_(31)H_(64)` is burnt = 31 moles
