Question

In this chemical reaction, how many grams of h2 will react completely with6.50 moles of CO

Answer 1

52 g of hydrogen H₂

Explanation:

I will assume that the problem is talking about the hydrogenation of carbon dioxide CO₂ not carbon monoxide CO. It is harder to reduce carbon dioxide than carbon monoxide and if you manage to reduce carbon dioxide you can reduce the carbon monoxide as well.

This reaction it will take place in the presence of catalyst at a specific temperature and pressure.

CO₂ + 4 H₂ → CH₄ + 2 H₂O

Now taking into the account the chemical reaction we devise the following reasoning:

if         1 mole of CO₂ react with 4 moles of H₂

then   6.5 moles of CO₂ react with X moles of H₂

X = (6.5 × 4) / 1 = 26 moles of H₂

number of moles = mass / molecular wight

mass = number of moles × molecular wight

mass of H₂ = 26 × 2 = 52 g
