<span>When chemical reactions take place, chemical bonds are broken in the reactants and new chemical bonds are formed in the products. It is as a result of these processes that a reaction is overall exothermic (energy is given out to the surroundigs) or overall endothermic (energy is absorbed from the surroundings hopefully this helped :)</span>
Kinetic energy = 1/2mv²
where m = 54kg
and v =3m/s
k.e = 1/2×54×3×3
= 1/2×54×9
= 1/2×426
= 486÷2
= 243J
please mark as brainliest
Since you did not give the reactions, i cannot give the answers.
In organic and inorganic chemistry, nucleophilic substitution is a fundamental class of reactions in which an electron rich nucleophile selectively bonds with or attacks the positive or partially positive (+ve)charge of an atom or a group of atoms to replace a leaving group; the positive or partially positive atom is referred to as an electrophile. The whole molecular entity of which the electrophile and the leaving group are part is usually called the substrate.
The most general form for the reaction may be given as the following:
