You have 16.7 grams of hydrogen and 15.4 grams of oxygen in a synthesis rxn. Which is the limiting reagent?

Oxygen is the limiting reagent in the following synthesis reaction.

Explanation:

At first, we have to balance the chemical reaction,

i.e.,oxygen molecule requires 2 moles of hydrogen molecule in order to synthesise 2 moles of water molecule.

no. of moles of =

                              =0.48125 moles

no. of moles of =

                               = 8.2841 moles.

Now, for 1 mole of oxygen,2 mole of hydrogen is used, so;

no. of moles of = 8.2841/2 = 4.142 moles.

But, we don't have that many moles of and that's why, oxygen is considered as limiting reagent.

i'm pretty sure its b i might be wrong though!

answer: they produce more slow than unicellular organisms.
