In the reaction of 11.84 g of metallic zinc with excess copper sulfate, 6.01 g of copper metal is formed: CuSO4 (aq) + Zn (s) \rightarrow→ Cu (s) + ZnSO4 (aq) What is the percent yield of this reaction, in %? Enter the numerical value only (no units or symbols), to one decimal place. Answer value
One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe (s) + CuSO4 (aq) → Cu (s) + FeSO4 (aq)Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 200.mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 73.mg . Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.

According to the following balanced reaction, how many moles of CaOCaO are required to exactly react with 6.55 moles of H2OH2O?CaOCaO(s) + H2OH2O(l) →→ Ca(OH)2Ca(OH)2(s)
Sodium hydrogen carbonate (NaHCO3), also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI), which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq) + NaHCO3(aq) → NaCl(aq) + H2O(l) + CO2(g) ->> The CO2 gas produced is what makes you burp after drinking the solution. Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 100. mL of a 0.089 M HCl solution. What mass of NaHCO3 would he need to ingest to neutralize this much HCI? Round your answer to 2 significant digits. x10 x
