Составьте уравнения химических реакций по предложенным схемам а)CuO+CO2=

I don't have access to the internet to look up the specific reaction, but to balance a chemical equation you need to ensure the number of each type of atom on the reactant side is equal to the number on the product side. Begin by balancing the elements that appear in the fewest compounds. You can start with Cu (copper) and balance it last.
