gpt
The combination formula in chemistry is A + B → AB and can be seen in reactions such as 2H2(g) + O2(g) → H2O(l) and CaO(s) + H2O(l) → Ca(OH)2(s).
Explanation: In the combination formula, reactants combine in a reaction to form a single compound which is usually illustrated with chemical examples like inorganic synthesis in various metal and non-metal applications.
