Given the balanced equation, 2 H2 + O2 -> 2 H2O, answer the following
question. If you have 10.0 GRAMS of H2 and 20.0 GRAMS of Oz, which is
the LIMITING REACTANT?
O H2
OO
O H₂O

is the limiting reagent

Explanation:

To calculate the moles :

The balanced chemical reaction is :

According to stoichiometry :

1 moles of require = 2 moles of

Thus 0.625 moles of will require= of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent as it is present more than the required amount.

girl imma just put my comment here because i need a couple point okurrttt
