and bQuestion: What is the percentage yield of calcium carbonate formed when calcium chloride reacts with sodium carbonate? PART A: Use the balanced chemical equation below to determine: (a) the limiting reactant (b) theoretical yield (mass) of calcium carbonate \(\underset{\mathrm{m}=3.75 \mathrm{~g}}{\mathrm{Na}_{2} \mathrm{CO}_{3}(\mathrm{qq})}+\underset{\mathrm{m}=4.82 \mathrm{~g}}{\mathrm{CaCl}_{2}(\mathrm{oq})} \rightarrow \underset{\mathrm{m}=?}{\mathrm{CaCO}_{3}(\mathrm{~s})}+2 \mathrm{NaCl}_{(\mathrm{oq})}\)

A reaction is done by dissolving 5.687 g sodium phosphate and 7.533 g of calcium chloride in water. These react to form solid calcium phosphate and sodium chloride (this remains dissolved in water). a) Write a balanced equation for the reaction; don’t forget states of matter b) How many grams of calcium phosphate are expected to form if all the sodium phosphate reacts? c) How many grams of calcium phosphate are expected to form if all the calcium chloride reacts?...

A 5.37 g mixture of sodium chloride and sodium carbonate is heated to decompose the sodium carbonate into sodium oxide and carbon dioxide according to the following chemical equation. Na2CO3 → Na2O + CO2 The sodium chloride will not decompose. If the final mixture has a mass of 4.03 g, what was the percent sodium carbonate in the original mixture? Hint: Consider the Law of Conservation of Matter - the mass of reactants must equal the mass of products. However,...

A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in HCl. After the fillers were filtered out, the HCl was neutralized by adding sodium carbonate. The resulting precipitate was pure calcium carbonate (with the fillers removed). The solid calcium carbonate was collected on a watch glass that had a mass of 46.719 g when empty. After the calcium carbonate had been allowed to dry, the mass of the watch glass plus product was found...
