4 nh3 + 3 0₂ 2n2 + 6h₂o
a. 20 moles of nha are needed to produce -
moles of 20.
b. how many moles of nz will be produced if 3.5 moles of oz react?

Explanation: was given the equation: Ca(OH)2 + H3PO4 --> H2O + Ca3(PO)4, which I balanced to:

3 Ca(OH)2 + 2 H3PO4 --> 6 H2O + Ca3(PO)4

I am supposed to find

a) How many grams of calcium phosphate are produced from the reaction of 25.0g of Ca(OH)2 with excess H3PO4.

b) If 0.139 moles of Ca(OH)2 react with 0.58 moles H3PO4, determine the grams of H2O produced and the grams of the excess reagent left after the reaction.

was given the equation: Ca(OH)2 + H3PO4 --> H2O + Ca3(PO)4, which I balanced to:

3 Ca(OH)2 + 2 H3PO4 --> 6 H2O + Ca3(PO)4

l dont know l am s sorry
