Question

find the number of moles of co2 in combustion of 0.4 mole of c2h4​

Answer 1

$C_{2}H_{4}+3O_{2}\rightarrow2CO_{2}+2H_{2}O$

$\sf{ \purple{from \: the \:chemical \: equation : }}$

$\sf{ 1 \: mole \: of \: C_{2}H_{4} \rightarrow2 \: moles \: of \: CO_{2}}$

$\sf{ 0.4 \: mole \: of \: C_{2}H_{4} \rightarrow \: ?}$

$\sf{ \purple{solving : }}$

$\sf{ 0.4 \: mole \: of \: C_{2}H_{4} \rightarrow0.4 \times 2 }$

$\orange{ \therefore\sf{ 0.4 \: mole \: of \: C_{2}H_{4} \rightarrow0.8 \: moles \: of \: CO_{2} }}$
