Analysis of a Penny 3. Indicate whether the ollowing compounds are soluble (sol) or insoluble (insol) in water ê·¸nsalã¼ are (a) NH C (c) Mg(NO3)2 (e) BaSO.4 (g) CuCrO4 (i) ZnS (b) Fe(C2H3O2)3 sol (d) Agl ASCaco, 105(h) AIPO nsol Sol 4. Write a balanced chemical equation for each of the following reactions. (a) potassium (s) chlorine(g) + potassium ch loridels) (b) calcium carbonate(s) calcium oxide(s) carbon dioxide(g) + (c) lithium metal(s) water(1) lithium hydroxide(aq) hydrogen(g) + â + (d) lead(II) nitrate(aq) + sodium iodide (aq) lead(II) iodide(s) + sodium nitrate(aq) â (e) acetic acid(aq) barium hydroxide(aq) barium acetate(aq) + â + water(1) 5. (optional) A 1980 penny weighing 3.079 g reacts with nitric acid to give a blue solution. An electric current is passed through the solution and 2.925 g of copper metal is produced. What is the percentage of copper in the 1980 penny? = 94.19 ertage of o
