The reaction of calcium oxide with water is exothermic, meaning it releases a large amount of heat.

When calcium oxide reacts with water, calcium hydroxide is produced.

In a chemical reaction, bonds between atoms are broken and new bonds are formed to produce new substances.

Atoms of one element do not change into those of another element during a chemical reaction.

Including physical states enhances the informativeness of a chemical equation by providing insights into the phases of reactants and products involved in the reaction. This helps in understanding the reaction’s stoichiometry, energetics, and practical considerations related to carrying out the ...
