The correct answer in apex is TRUE!
the correct answer on apex is false
Yes when two different substances join to make a single substance.... that is a combination reaction for example:-
C + O2 ------> CO2
CaO + CO2 ----> CaCO3

The substances you have at the beginning of a chemical reaction are called the reactants.
CaCl2
Dark Reaction
It provides energy to overcome the activation energy.

A combination reaction is a reaction in which two elements (or other substances) combine to form a new compound.A combination reaction occurs when one reactant forms two or more products.

It is not a chemical reaction, it is only a dissociation reaction:NaCl-------------------------Na+ + Cl-
The amounts of reactants and products are not mentioned.dark
A reactant is the starting material of a reaction. For example, in the reaction 2H(+) + O(2-) --> H2O, both H(+) ions and the O(-) ion are the reactants, whereas H2O is the product of the reaction. A reactant is something that REACTS.
A chemical reaction occurs between sodium hydroxide and hydrogen chloride. Adding more sodium hydroxide to the reaction causes it to speed up. If you add more of a reactant, such as sodium hydroxide, can it be considered a catalyst? Why or why not?
CaCl2
Endothermic.
After a chemical reaction the reactants are transformed in products.
