Write the balanced molecular equation for the reaction of copper(II) oxide react

Question

Write the balanced molecular equation for the reaction of copper(II) oxide reacts with sulfuric acid to lorm copper(ll) sultate and water. Be sure to include in your equation the various states of the reactants and products. After the reaction that occurred in question 2, if you tested the solution with litmus paper, what color would the paper be? A student performed the copper experiment starting with a 037 g of copper wire. At the end of the experiment, the student recovered a mass of 0. 32 g of copper. What is the percent recovery ot the copper metal?

Explanation / Answer

a)CuO(s) + H2SO4(aq) = CuSO4(s) + H2O(aq)

b) The litmus paper will turn red in color.

because copeer sulfate is acidic in nature.

c) 0.37 grams recovery is 0.05 grams

   100 grams recovery is ? grams

=> 100*( 0.05 )/0.37= 13.5 % recovery of copper metal.
