1- The concentration of bromide ion may be determined by gravimetric analysis, using this reaction: Ag * (aq) Br (aq) AgBr (s) A 0.500-L aqueous solution containing bromide was reacted with excess Ag. If the AgBr precipitate formed in this reaction has a mass of 0.0035 g, how many moles of Br were in the solution? What was the molarity of Br in the solution? 2-Identify each of these reactions as precipitation, neutraliza tion, or metal displacement: a. Ba (OH),...

2. When zinc metal reacts with copper(II) nitrate, zinc(II) nitrate and copper metal are the products. How many grams of zinc metal are required to react completely with 725 mL of 0.1955 M copper (II) nitrate solution? What mass of copper metal is produced? You will need a balanced equation to solve this problem! 3. One step in the process of manufacturing nitric acid (HNO3), a staple industrial chemical, is 3 NO2 (g) + H20 (1) ► 2HNO3...

Dissolution of Copper Metal Copper reacts readily with strong oxidizing agents (substances that readily remove electrons from other suhstances-i.e... Cu- Cu2 +2e). In this experiment, aqueous nitric acid, HNO, oxidizes copper metal to the copper(II) ion (opening photo): Cu(s) +4 HNO,(aq)Cu(NO)(aq) +2 NO (8) +2 H,0( .Cu HNO3 Cu(NO3)2 (28.1) CuSO The products of this reaction are copper(II) nitrate, Cu(NO)2 (a water-soluble salt that produces a blue solution), and nitrogen dioxide, NO2 (a dense, toxic, red-brown gas). The solution remains...

1. Write a balanced chemical equation for the oxidation of zinc metal (Zn) by copper(II) ions (Cu?") in a copper sulfate solution. Note that copper(II) sulfate completely dissociates in aqueous solution and forms Cu2+ (aq) and SO,- (aq) in water. Zinc metal is a solid and should be represented as Zn (3) Write a chemical equation for the decomposition of limestone (CaCO,) by heating to high temperature to drive off carbon dioxide. The other product of this decomposition reaction is...

Practice 1. An aluminum wire is placed in 60.0 mL of an unknown copper(II) chloride dihydrate solution. The copper(II) and aluminum react in the redox reaction below, producing solid copper: 3 Cu (aq) 2 Al(s) -3 Cus) 2 Al (aq) The solid copper was filtered using a Büchner funnel, and then was dried one time and weighed to be 0.256 g. It was dried a second time and weighed to be 0.235 g. It was dried a third time and...

What is the reduction half-reaction? In the electrolytic cell of this experiment, copper metal is the anode and zinc metal the cathode. The electrolyte solution is sulfuric acid, H2SO4. Oxidation occurs at the copper anode, where Cu is oxidized to Cu^2+: Cu (s) → Cu^2+ (aq) + 2 e– During the experiment, you might have noticed that at the end of the trials, the solution becomes slightly blue, which proves the existence of aqueous Cu^2+. What is the reduction half-reaction...

It is expected that a chemical reaction will occur when copper metal is combined with aqueous zinc sulfate. Explain why there will be no reaction when zinc metal and aqueous copper sulfate solution are combined. Identify the anode and the cathode, assuming a voltaic cell is constructed. Note: Be careful in the calculation of the standard cell potential ( Eo cathode - Eo anode). Do not change the sign of the given reduction potential. The sign is already taken care...
