WebIn many chemical reactions, the reaction will proceed only in the forward direction, from products to reactants. Some chemical reactions are however reversible. This means that they can proceed in the backward direction, from products to reactants. WebNov 29, 2024 · Reactions will often be shown as displayed formulae so it is easier to work out which bonds are being broken and which bonds are being made. H-O-O-H H-O-H → + O=O H-O-O-H H-O-H On the left-hand side of the equation, the bonds are breaking. There are four O-H bonds and two O-O bonds. So, (4×464) + (2×146) = 2148
