yes they are, Thank u:)
May i clarify one point ? I m not sure how come there’s a new variable x introduced in the table ^^ What does it mean? Thank u!
Because the change in amt of the products and reactants are also unknowns. But because u know that they must have the same ratio as the chemical equation, u can relate them with a single variable x.
