Question

CH₂ + O₂ CO₂ + H₂O

If you
have
5 mol of O₂ how many
mol of CO2 can be produced?

Answer 1

`(10)/(3)`

Step-by-step explanation:

The reaction expression is given as:

CH₂ + O₂ → CO₂ + H₂O

The reaction above needs to be balanced first. Let us take a mathematical approach to solve this;

aCH₂ + bO₂ → cCO₂ + dH₂O

Conserving C: a = c

H: 2a = 2d

O: 2b = 2c + d

let a = 1, c = 1, d = 1 and b =
`(3)/(2)`

Multiply through by 2;

a = 2, b = 3, c = 2 and d = 2

2CH₂ + 3O₂ → 2CO₂ + 2H₂O

From the balanced reaction expression;

3 moles of O₂ will produce 2 moles of CO₂

5 moles of O₂ will produce
`(5 x 2)/(3)` moles of CO₂ =
`(10)/(3)`
