Question

If you carry out the reaction between table salt (NaCl) and copper(II) sulfate (C11SO4) in 100.0 mL of water, the salt copper(II) sulfate will behave similarly to the salts given in the tab named Slightly Soluble Salts. Enter the formula for the precipitate (without the phase) that will be formed. If no precipitate is formed, simply type "noreaction" in the answer box. Express your answer as a chemical formula. 2NaCl(aq) + CuCl2(aq) rightarrow Na2 CuCl4(aq) Submit My Answers Give Up Review Part Incorrect; Try Again; 3 attempts remaining When heated, solid copper(II) carbonate decomposes to solid copper(II) oxide and carbon dioxide gas. Give the balanced chemical equation (including phases) that describes this reaction. Indicate the phases using abbreviation (s), (I), or (g) for solid, liquid, or gas, respectively. Express your answer as a chemical equation. CuCO3(s) rightarrow CuO(1) + CO2(s) Submit My Answers Give Up Review Part Incorrect; One attempt remaining; Try Again

Explanation / Answer

1) no reaction

2NaCl + CuS04 ---> CuCl2 + Na2S04

both CuCl2 and Na2S04 are soluble in water. So no precipitate is formed.

2) CuC03(s) ------> Cu0 (s) + C02 (g)
