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.

the answer is barium and copper bromide

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
