<h3>Further explanation</h3>

Given

Reaction

MgCl2 + Li2CO3 → MgCO3 + LiCl

Required

Balanced equation

Reaction type

Solution

Balanced equation

Li2CO3 (s) + MgCl2 (aq) → MgCO3 (s) + 2 LiCl (aq)

Double-Replacement reactions. Happens if there is an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product  

To predict whether this reaction can occur or not is one of them, the precipitation reaction.

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.
