reactants
During a chemical change, matter undergoes a chemical reaction where its chemical composition is altered. This can result in the formation of new substances with different properties than the original matter. Chemical bonds are broken and new bonds are formed, leading to a reorganization of the atoms in the substance.
The burning of a wooden stick is a chemical process.
The results of a chemical reaction are called the products, and the reactants are what goes into the reaction
This is an endothermic reaction.
Phisical re action: when the wax turns to liquid when the liquid cools down it turns to solid which goes back to its own form again soryy i don't know the chemical reaction
Mono-atomic ions do not undergo a chemical change during a chemical reaction.
A chemical reaction occur.

wow, did you copy this offf of a science worksheet? lol and it is "it changes" and when it goes under physical change "it remains the same"

The browning of a flower is a chemical change. Color changes are one sign of a chemical reaction.
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.

Yes.
When a chemical change does not go to completion, some reactants may remain after the reaction has reached equilibrium. This can result in a mixture of both reactants and products in varying amounts. The extent to which a reaction goes to completion depends on factors such as reaction conditions, reactant concentrations, and the presence of catalysts.
It is a chemical change, even though the cigarette is getting physically smaller. When heat is added and you inhale the chemicals, the cigarette burns and you blow out smoke which in itself is a chemical reaction that cannot be reversed. Therefore, it's purely chemical. Remember that chemical changes cannot be reversed and physical changes can. Freezing water and then melting it is an example of a physical change. The example you mentioned is a chemical change.
