Answer 1

Explanation:

the required answer is in the attatchment.....

Answer 2

Answer:

combination reaction

= the reaction in which two or more reactant are combined to form only one product is called combination reaction.

example-:mg + o2 = mgo

decomposition reaction

= the reaction in which one reactant is decomposed into two or more than two product is called decomposition

reaction. example: mgo= mg+o2

oxidation reaction

=the reaction in which their is a gain of oxygen or loss of hydrogen is called oxidation reaction. example:c+o2=co2

reduction reaction

= the reaction in which their is loss of oxygen and gain of hydrogen is called reduction reaction. example:cuo + c= cu + co.
