Carbon reacts with steam (h2o) at high temperatures to produce hydrogen and carbon monoxide. if 2 mol of carbon are exposed to 3.1 mol of steam how much h2 is formed? answer in units of mol.

The balanced equation for the above reaction is as follows;

C + H₂O - - - > H₂ + CO

stoichiometry of C to H₂O is 1:1

1 mol of C reacts with 1 mol of H₂O

we need to find which is the limiting reactant

2 mol of C and 3.1 mol of H₂O

therefore C is the limiting reactant and H₂O is in excess.

stoichiometry of C to H₂ is 1:1

then number of H₂ moles formed are equal to C moles reacted

number of H₂ moles formed = 2 mol
