Question

How many moles of CO2 are produced when 1 mole wax C31H64 is burned? 31 32 64 or 47

Answer 1

Answer:

31 moles.

Explanation:

The products of combustion are CO2 and H2O.

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

Answer 2

Answer:

31 moles

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
