A student made the Lewis dot diagram of a compound as shown. Mg is written with two dots shown on its top. Cl is written on the
blsea [12.9K]

Answer:

The dots were not properly located and arrows are not used in Lewis structures

Explanation:

If we intend to write a Lewis structure for a compound, that lewis structure must consist of only dots. These dots actually show the valence electrons on the outermost shell of the molecule.

We do not involve arrows when writing dot electron structures for compounds. The valence electrons of magnesium ought not to be written together because they are not a lone pair, rather they are two unpaired electrons. The use of an arrow suggests a coordinate covalent bond which is not the case here.

The correct lewis structure for MgCl2 is shown in the image attached to this answer.

For the reactionN2(g)+O2(g)?2NO(g)classify each of the following actions by whether it causes a leftward shift, a rightward shif
Soloha48 [4]

Answer: Le Chatleir Principle

Explanation:  The answer of this question can be easily explanied through the Le Chatleir Principle which states that In order to maintain the equilibrium of the reaction, the stress applied to that particular direction will move the equilibrium to the opposite direction in which the stress has been applied.

The given reaction is -

      N_{2}(g)+O_{2}(g)\rightleftharpoons 2NO(g)

If the amount of the oxygen is reduced to half and is being doubled, then the reaction will move in froward direction that is a rightward shift. Same situation will arise in option c and d.

If the amount of nitrogen monoxide is reduced to half or being doubled, the reaction will move towards backward direction that is a leftward reaction.

Look at sample problem 18.15 in the 8th ed Silberberg book. Identify the Lewis acids and Lewis bases in the following reactions:
Lelechka [254]

Answer:

1. H+ + OH- <--------> H2O

H+ is a Lewis acid

OH- is a Lewis base

2. Cl- + BCl3 <---------> BCl4-

Cl- is a Lewis base

BCl3 is a Lewis acid

3. K+ + 6H2O <------> K(H2O)6+

K+ is a Lewis acid

H2O is a Lewis base

Explanation:

By definition, Lewis acid is an electron pair acceptor while a Lewis base is an electron pair donor.

Potassium ion accept electron pairs from 6 water molecules which donate the electron pairs.
