WebWhen chemical reactions occur, energy is transferred to (exothermic) or from (endothermic) the surroundings. Importantly, it is the particular process of the chemical reaction, that either generates heat ( exothermic) to, or absorbs heat ( endothermic) from, the surroundings. 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
