Question

Can you tell from the masses of the reactants which one of the reactants will be the limiting reactant? Defend your answer (use an equation within your defense).

Answer 1

No, usually you would do the math first before deciding which is the limiting reactant

Step-by-step explanation:

2H₂(g) + O₂(g) -----> 2H₂O(g)

3mol= Hydro

2mols= O₂

The limiting reactant would be the smaller number after we divide the number of moles by the coefficient

H:1.5 3mol/2(c) =1.5

O2: 2 2mol/1(c)=2

Hydrogen is lower = limiting reactant
