WebOct 5, 2024 · Given the unbalanced equation C 4 H 10 + O 2 ---> CO 2 + H 2 O. First you would balance H and then balance O. After that, you should have C 4 H 10 + 13/2 O 2 ---> 4 CO 2 + 5 H 2 O Remember that stoichiometric coefficients should be whole numbers, so multiply everything by 2 to get rid of the improper fraction and get WebAll chemical equations must be balanced. This means that there must be the same number of each type of atom on both sides of the arrow. To balance a chemical equation, place coefficients as needed in front of the symbols or formulas so the same number of each type of atom occurs in both reactants and products.
