Equal masses (in grams) of hydrogen gas and oxygen gas are reacted to form water. Which substance is limiting?
a. Oxygen gas is limiting
b. Hydrogen gas is limiting.
c. Water is limiting.
d. Nothing is limiting.
e. More information is needed to answer this question

Answer:

a. Oxygen gas is limiting

Explanation:

2H₂ + O₂  →  2H₂O

the above balanced equation shows that 2 moles of Hâ‚‚ is required for 1 mole of Oâ‚‚

Given equal masses of Hâ‚‚ and Oâ‚‚

assuming 'x' gm for each, no. of moles of each gas  =

no. of moles of Hâ‚‚ = x/2 = 0.5x moles

no.of moles of Oâ‚‚ = x/32 = 0.031x moles

This shows that no. of moles of Oâ‚‚ is very less so Oâ‚‚ will become the limiting reagent.

Answer:

the answer is a. oxygen gas is limiting.

Explanation:

a. Gas is a form that can turn into water from extreme heat or can turn into gas from extreme heat evaporating the water it began with.

b. hydrogen can't 'shapeshift' to different forms

c. water can't turn into water because water is water.

d. something is being limited

e. the question has plenty of information

So the answer would be A :)
