A sample of zinc metal is allowed to react completely with an excess of hydrochloric acid: Zn(s) +2 HCl(aq) → ZnCl2(aq) + H2(g) The hydrogen gas produced is collected over water at 25.0°C. The volume of the gas is 8.55 L, and the atmospheric pressure is 0.971 atm. Calculate the amount of zinc metal in grams consumed in the reaction. (Vapor pressure of water at 25°C = 23.8 mmHg.) g Zn 117 MAR 664 17 18 étv A

Redox is a type of chemical reaction in which the oxidation states of the substrate change. Electrons will move from the right electrode to the left. Describe the role/what happens to copper and silver in the redox process. Copper is in the left beaker and silver is in the right. use CER, claim, evidence, and, reasoning. Claim is your answer, evidence is from the image and, reasoning is your explanation.

Solve correctly please. Should correct (Gpt/ai answer not allowed)

Step 4 you need to clean off the MgO from the surface of the Mg metal. What would happen to the amount of H2 that you would produce if you did NOT clean off the Mg0? Would the amount of H2 increase, decrease, or stay the same. Be sure to explain why and justify your answer.

Explain what effect each of the following will have on the actual yield of the recovered Cu (s). Student used ethanol instead of cold water to rinse the copper product. Not all of the Zn (s) reacted with the added H2SO4, so that some of the zinc remained with the copper product. When decanting off the supernatant in Step 6 some black solid also came over and was discarded instead of remaining behind in the reaction beaker. When heating the Cu(OH)2, some solution and solid splattered out of the beaker when the solution boiled over.
