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

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

Answer 2

Answer:

2 moles of CO2 will be produced

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.
