Balance the following reaction: Co(NO 3 ) 2 (aq)(aq) + Na 3 PO 4 (aq) %u2192 Co

Question

Balance the following reaction:

Co(NO3)2(aq)(aq) + Na3PO4(aq) %u2192 Co3(PO4)2(s) + NaNO3(aq)

Using the balanced equation, starting concentrations and the initial volumes, determine the limiting reagent for this part.

Notes for calculation purposes:

1. Assume 20 drops = 1 mL.

2. Report all answers to two significant figures.

Initial moles Co(NO3)2 = mol

Initial moles Na3PO4 = mol

Number of moles of Co3(PO4)2 that can be formed from each starting reagent is:

from Co(NO3)2 = mol Co3(PO4)2

from Na3PO4 = mol Co3(PO4)2

Give the chemical formula for the starting solution that was the limiting reagent?

Explanation / Answer

Balanced equation:
3 Co(NO3)2(aq)(aq) + 2 Na3PO4(aq) = Co3(PO4)2(s) + 6 NaNO3(aq)

you need to provide more details for the rest of the calculation and get your answer.
