Answer 1

Answer:

o2 is limiting reagent hope so it would help

Explanation:

im thinking you are jnv student coz just nowin my qp same question came

Answer 2

Answer:

Oxygen

Explanation:

In order to understand which is the limiting reagent, let us first write the balanced chemical equation

2H2 + O2 == 2H20

If we look at the above equation, 2 moles of hydrogen gas and one mole of oxygen gas are required to produce two moles of water.

Now we have the following reagents;

2 grams of Hydrogen = 1 mole

8 grams of Oxygen = 0.25 moles

Since oxygen quantity is less, so it will be the limiting reagent
