Question

Formaldehyde (h2co) reacts with oxygen to form co2 and h2o. how many moles of co2 will be produced from reacting 2 moles of h2co with oxygen?

Answer 1

2 moles of CO2 will be produced

Step-by-step explanation:

Chemical equation for the reaction will be

Formaldehyde + oxygen → CO₂ + H₂O

H₂CO + O₂ → CO₂ + H₂O

Since the equation is already balanced so

Taking the mole ratios

1 mol H₂CO : 1 mol O₂ : 1 mol CO₂ : 1 mol H₂O

We can see that every mole of H₂CO produces 1 moles of CO₂ , which means that 2 moles of CO₂ are produced from reacting 2 moles of H₂CO with oxygen.

Answer 2

Answer:
2 mol of CO₂

Solution:

The reaction is as follow,

H₂CO + O₂ → CO₂ + H₂O

According to this equation,

1 mole of H₂CO produces = 1 mole of CO₂
So,
2 moles of H₂CO will produce = X moles of CO₂

Solving for X,
X = (2 mol × 1 mol) ÷ 1 mol

X = 2 mol of CO₂
