Question

on a glass of 20g of copper oxide(II) is added 0.2dm3 h2so4,caclulatr the amount of CuSO4 formed by this reaction?

Answer 1

What is the reaction taking place?

copper(II) oxide = CuO

CuO + H₂SO₄ ==> CuSO₄ + H₂O

In order to answer the question as asked, we would need to know the concentration of the H2SO4 so that we can determine if CuO or H2SO4 is present in limiting amount. Without that knowledge, we cannot answer this.
