How many total electrons are shared between two nitrogen atoms when they bond to form a diatomic nitrogen molecule?
GuDViN [60]

Explanation:

Diatomic Nitrogen molecule means the two atoms of nitrogen N_{2}.

  • A single nitrogen contains 5 electrons in its valence shell which has 3 single electrons and one pair of electron. When the bond is being made the three single electrons makes the covalent bond with the 3 electrons of other atom which results in 3 pairs . The total electrons shared between the atoms are 3 pairs  (6 electrons) . while when it completes the octate the N_{2} is formed.
  • Nitrogen is colorless, odorless, tasteless and the inert diatomic gas.Nitrogen combines of near about 78% of Earth's atmosphere.It is non-flammable which does not support combustion , it occurs in all living organisms. Nitrogen is used in most of the Biological processes  and also used in the formation of fertilizers, in the form of ammonia and ammonia based compounds.It is also used in Chemical Industries for making nylon , explosives, dyes and etc. The breathing of Nitrogen is deadly, as it displaces the oxygen.

What is the net ionic equation for the reaction that occurs when aqueous solutions of naoh and hno3 are mixed?
likoan [24]

Answer:-

H+ + OH- --> H2O

Explanation:-

The chemical equation is NaOH + HNO3 --> NaNO3 + H2O

Now for the ionic compounds

HNO3 --> H+ + NO3 -

NaOH--> Na+ + OH-

NaNO3 --> Na+ + NO3-

Water being covalent will remain as H2O,

Hence

HNO3 + NaOH--> NaNO3 + H2O

H+ + NO3 - + Na+ + OH- --> Na+ + No3 - + H2O.

Crossing out common terms

H+ + OH- --> H2O

Gennadij [26K]

Answer:

Mechanical energy

Kinetic energy

Explanation:

The mechanical energy is the sum of the kinetic and potential energy of the particles that make up the baseball.

Mechanical energy is made up of kinetic energy and potential energy. When the baseball is in motion, the particles make use of the kinetic energy, also known as motion energy and when the ball is not in motion the particles make use of the potential energy, also known as stored energy.
