Question

The balanced equation below represents the reaction between carbon and hydrogen to produce

ethane.
2C(s) + 3H2(g) → C2H6(g) + energy
Determine the number of moles of O2(g) needed to completely react with 8.0 moles of CO(g).


Please help!!!

Answer 1

4.0 moles

Step-by-step explanation:

Based on the given reaction between carbon and hydrogen, the equation of the reaction between O₂ and CO is as follows:

2CO(g) + O₂(g) → 2CO₂(g)

The number of moles of O₂ needed to completely react with 8.0 moles of CO can be calculated knowing that 2 moles of CO react with 1 mol of O₂:

`n_{O_(2)} = (1 mol O_(2))/(2 moles CO)*8.0 moles CO = 4.0 moles O_(2)`

Therefore, the number of moles of O₂ needed is 4.0.

I hope it helps you!
