The mass of calcium chloride formed when 2.5 g calcium cabonate are dissolved in excess of hydrochloric acid is?
Calcium chloride (CaCl2) resulted: 2,772 g.
Calculate the theoretical yield of calcium chloride expected for this reaction if 0.80 mol of calcium hydroxide is reacted with excess hydrochloric acid.?
0.80
What mass of carbon dioxide will be produced?
Full question: Ordinary chalkboard chalk is a solid mixture with limestone (calcium carbonate) and gypsum (calcium sulfate) as its principal ingredients. The limestone dissolves in dilute hydrochloric acid, producing calcium chloride, carbon dioxide, and water. 1.) Gypsum does not react with HCl. If a 5.05g piece of chalk that is 72.0% calcium carbonate is dissolved in excess HCl, what mass of carbon dioxide will be produced? 2.) Determine the mass percent of calcium carbonate in a 4.38g piece of chalk that yields 1.31g carbon dioxide when it reacts with excess HCl?
In the reaction of silver nitrate with sodium chloride how many grams of silver chloride will be produced from 100 g of silver nitrate when it is mixed with an excess of sodium chloride?
58.9g
Does calcium chloride and water form hydrochloric acid?
No, they simply form a solution of calcium chloride. This is correct, but one should add that the solution heats up because of the exothermic process involved when water causes the calcium chloride crystals to dissolve; the calcium chloride is dissociated into calcium and chloride ions. However, the question is why does the solution test as an acid when phenol red is added? The red solution turns yellow indicating an excess of hydrogen (hydronium) ions. There is no adequate answer that I could find on the Internet.

When 10.0 grams of calcium reacts with 20.0 grams of chlorine gas, how many grams of calcium chloride can be produced Which reactant is in excess and which is the limiting reactant?
The balanced chemical equation for the reaction between calcium and chlorine gas to produce calcium chloride is: Ca + Cl2 -> CaCl2. From this equation, we can see that one mole of calcium reacts with one mole of chlorine gas to produce one mole of calcium chloride. The molar mass of calcium is 40.08 g/mol and the molar mass of chlorine gas is 70.90 g/mol. This means that 10.0 grams of calcium is equivalent to 0.249 moles of calcium and 20.0 grams of chlorine gas is equivalent to 0.282 moles of chlorine gas. Since the ratio of calcium to chlorine gas in the balanced chemical equation is 1:1, this means that 0.249 moles of calcium would react completely with 0.249 moles of chlorine gas, leaving an excess of 0.033 moles (or 2.34 grams) of chlorine gas. The limiting reactant in this reaction is calcium, and the maximum amount of calcium chloride that can be produced is equivalent to the number of moles of the limiting reactant, which is 0.249 moles (or 27.8 grams) of calcium chloride.

What happens to Calcium chloride in air?
When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.
