Cu + H2SO4 = CuSO4 + SO2 + H2O

Balanced Chemical Equation – Solution

Cu + 2H2SO4 → CuSO4 + SO2 + 2H2O

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
