Is it chemical change that makes you afraid of leaving innocence in the world?

I'm not afraid of being smashed to pieces. Being innocent in the world is a chemical change. There are two reactions in this poem: the reaction between quicklime and water and the reaction between calcium hydroxide and carbon dioxide, both of which are chemical changes. The way to solve the problem is that if there is no new substance, it belongs to physical change, and if there is new substance, it belongs to chemical change.

Examples of chemical changes and physical changes:

Physical change: three-state change of water; Grinding gallstones into powder; Pouring molten iron into an iron pot; The stick is broken; Salt dissolves in water and becomes salt water; Hydrate into ice; Broken glass; The vase is broken; Rice is ground into powder; The water is frozen.

Chemical change: the burning of magnesium bars; Basic copper carbonate is decomposed by heating; Iron rusts in humid air: gunpowder explodes; Burn paper; Food is moldy; Iron will rust; Combustion of magnesium; Basic copper carbonate is decomposed by heating; Wood will burn.
