A balanced equation for the reaction is
1.
a.The limiting reagent is the reactant that has the least number of moles.
Number of moles of CaCl2
Number of moles of Na2CO3
Therefore, the limiting reagent in this case is
b. Calculate the mass of calcium carbonate using the balanced equation reaction ratio 1:1
Therefore number of moles of Calcium carbonate is 0.004.
Calcium carbonate mass = 0.4g
2.Upon heating the particle size of CaCO3 smaller particles favours higher crystalization and their sizes increases.
