When nitrogen and magnesium form an ionic bond, what is the formula?
2 answers:
<u>Answer:</u> The chemical formula for the given compound is
<u>Explanation:</u>
Magnesium is the 12th element of the periodic table having electronic configuration of
This element will loose 2 electrons and form an oxidation state of +2 units.
Nitrogen is the 7th element of the periodic table having electronic configuration of
This element requires 3 electrons and thus shows an oxidation state of -3 units.
By criss-cross method, the oxidation state of the ions gets exchanged and this form the subscripts of the other ions. It results in the formation of a neutral compound.
Thus, the chemical formula for the given compound is

Answer: A large amount of energy is released into the surroundings.
Explanation:-
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and which is difference between energy of products and energy of reactants come out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and which is difference between energy of products and energy of reactants comes out to be negative.
Thus a reaction in which large amount of energy is released is categorized as exothermic reaction and thus respiration is also a exothermic reaction.
