Which is the limiting reagent when 9 Ca atoms and 8 H3PO4 mo

Which is the limiting reagent when 9 Ca atoms and 8 H3PO4 molecules react and produce 3 molecules of Ca3(PO4)2 and 9 molecules of H2? Write a balanced chemical equation.

a. H2

b. H3PO4

c. Ca

d. Ca3(PO4)2

e. None of these.

Solution

ca is the limiting reagent and balanced equation have 2,2,1,3 moles of ca ,h3po4,ca3po42,h2. repectively
