Answer to Question #263840 in General Chemistry for jho

Question

Sulfuric acid (H2SO4), a highly corrosive strong mineral acid, reacts with Cu according to this equation: 2H2SO4 + Cu → CuSO4 + 2H2O + SO2 How many grams of sulfur dioxide (SO2) are created by this reaction if 4.78 mol of Cu react with the H2SO4?

Answer 1

CU:SO2= 1:1

= 4.78

H2SO4:SO2= 2:1

= 4.78/2= 2.39

4.78+2.39= 7.17moles
