A 0.5g mixture of Cu and CuO was treated with hydrogen at elevated temperature. CuO was reduced to Cu.

Question

Q1.) write a balanced equation for the reaction

Q2.) before the experment, calculate the minimum amount in mole of hydrogen required to ensure the reduction is completed

Answer 1

CuO+H2>>Cu + H2O

2. assume all the .5g is CuO. Figure moles of CuO with that mixture, then you need same number of moles of H2.
