This video is the most important for grade11 or grade12 to improve about redox equation in acid.
To balance chemical equation:
1- balance the atom different from oxygen or hydrogen firstly
2- balance the oxygen atom if lack of oxygen atom; must add water molecule
“ if lack of one oxygen atom, have to add one water molecule”
“ if lack of two oxygen atom, have to add two water molecule”
“ if lack of three oxygen atom, have to add three water molecule”
3- balance the hydrogen atom if lack of hydrogen atom, must add ionic hydrogen or ionic hydronium.
4- balance electrons; it is added to the left or right that is excess.
welcome your question.
