Question

PLEASE HELP!!! FAN + TESTIMONIAL + MEDAL FOR FIRST STEP-BY-STEP ANSWER!!!
How many moles of sodium carbonate are consumed to produce one mole of sodium carbonate?
CaCO3 -> CaO (s) + CO2 (g)
NaCL (aq) + NH3 (g) + H2O (l) + CO2 (g) -> NH4CL (aq) + NaHCO3 (s)
2NaHCO3 (s) + heat -> Na2CO3 (s) + CO2 (g) + H2O (g)

Answer 1

Do you mean Calcium carbonate?

Answer 2

The first sodium carbonate is calcium carbonate, sorry.

Answer 3

Have these already been balanced?

Answer 4

I'm a bit too tired to be doing the balancing if so.

Answer 5

From these equations we can conclude that:
1 mole of CaCO3 is required to produce 1 mole of CO2, and 1 mole of CO2 will produce 1 mole of NaHCO3. but 2 moles of NaHCO3 are required to produce 1 mole of Na2CO3.
So:
2 moles of CaCO3 are required to produce 2 moles of CO2, and 2 moles of CO2 will produce 2 moles of NaHCO3. now these 2 moles of NaHCO3 are required to produce 1 mole of Na2CO3.

Answer 6

Thanks that's what I thought @waxynaveed
