Book Print Limestone (CaCO3) is used to remove acidic pollutants from gases inside smokestack flues. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite. Assuming a 78.1% yield in the overall reaction, what mass of limestone is required to remove all the sulfur dioxide formed by the combustion of 9.3 x 104 kg of coal that is 0.49 mass % sulfur? x 10 g Caco3

For the experiment " limiting reactant " and after filtering the precipitate, you checked the filtrate (supernatant) to identify the limiting reactant. 2Na3PO4 + 3BaCl2 → Ba3(PO4)2 (s) + 6NACI If you added BaCl2 to the filtrate (supernatant) and a white precipitate was formed, this means that: O a. None of the mentioned O b. BaCl2 is an excess Oc. Both BaC2 and Na3PO4 are limiting reactants O d. BaCl2 is the limiting reactant O e. NagPO4 is the limiting reactant
We did a gravimetric analysis of an unknown sulfate sample (dissolve in water with HCl) and reacted it with BaCl2. The precipitate was BaSO4. The mass of the unknown sample was 0.4145 grams while the mass of the precipitate after the experiment was 0.4146 grams. Upon doing stoichiometry on this result, I found out that the %SO4 in the unknown sample is equal to the %SO4 in the precipitate. My questions are: Is it theoretically possible that the mass of the unknown sulfate sample is equal to the mass of the BaSO4? Because upon hypothetically using Na2SO4 as the unknown sulfate sample, the stoichiometry tells me that the precipitate should weigh more than the reactant (meaning that the ppt should weigh more than 0.4145g which is ~0.5569g). Is it right to say when the %SO4 in the precipitate is equal to the %SO4 in the unknown sample, then they are both the same compound? Is it right to say that the unknown sulfate sample (reactant) in this experiment was also BaSO4? Is it right to…

When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. A solution is created by dissolving 12.5 grams of ammonium chloride in enough water to make 295 mL of solution. How many moles of ammonium chloride are present in the resulting solution? When thinking about the amount of solute present in a solution, chemists report the concentration or molarity of the solution. Molarity is calculated as moles of solute per liter of solution. What is the molarity of the solution described above? To carry out a particular reaction, you determine that you need 0.0500 moles of ammonium chloride. What volume of the solution described above will you need to…
