How do you balance this equation using the oxidation number method only?
ClO4)-1 +Al+H)+1---->Cl-1 +Al+3 +H2O
Also, How many mole of Fe2+ react with each mole of cr2O7)-2 when properly balanced 6?
Cr2O7)2- + H+ +Fe2+ ---->Fe3+ Cr3+ +H2O
The solution is comprised for a detailed step by step explanation of how to balance a chemical equation using the oxidation number method.
