Question

Explain the following reactions :
a) Precipitation reaction
b) Exothermic reaction
c) Neutralization reaction
d) Double displacement reaction
e) Redox reaction

Answer 1

ANSWER:

a) A precipitation reaction is a type of chemical reaction in which two soluble salts in aqueous solution combine and one of the products is an insoluble salt called aprecipitate. ... Note that not all ionic compounds react to form precipitates.

b)reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy. Exothermic Reaction means "exo" meaning releases and "thermic" means heat.

c) Neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. Theneutralization of a strong acid and strong base has a pH equal to 7. 

d) A double displacement reaction is a type ofreaction in which two reactants exchange ions to form two new compounds. Double displacement reactions typically result in the formation of a product that is a precipitate. Double displacement reactionstake the form: AB + CD → AD + CB.

e) Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.

Answer 2

Answer:

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.Nov 4, 2020
