it is the reactants which give the product
These are not chemical reactions but thermonuclear reactions.
The rate of chemical reactions is how long a chemical reaction takes to finish.
A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.
The reaction arrow in chemical reactions signifies the direction in which the reaction proceeds. It shows the transformation of reactants into products and indicates the flow of the reaction.
Proteins are chemical compounds, not reactions.
endergonic reaction
Chains of chemical reactions are sequences of reactions where the product of one reaction becomes the reactant of the next reaction in the chain. These reactions are often interconnected as part of a larger process. One example is the chain of reactions in a combustion reaction, where the heat produced from one reaction triggers subsequent reactions.
Neutralization
Burning a cigarette is a chemical reaction.
Catalysis reaction are the generic potential energy. Chemical reactions is the process that leads to the transformation of a set chemical.
Chemical reactions are of course chemical changes.
An endothermic reaction is a chemical reaction that absorbs energy. Such reactions usually produce a temperature drop.
