When a solution of MgCl₂ and a solution of AgNO₃ are mixed, the net ionic equation obtained is:
2Cl¯(aq) + 2Ag⁺(aq) —> 2AgCl(s)
<h3>What is a chemical equation? </h3>
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
<h3>How to write the net ionic equation </h3>
In solution
MgCl₂(aq) —> Mg²⁺(aq) + 2Cl¯(aq)
AgNO₃(aq) —> Ag⁺(aq) + NO₃¯(aq)
The reaction proceeds as follow
MgCl₂(aq) + AgNO₃(aq) —>
Mg²⁺(aq) + 2Cl¯(aq) + 2Ag⁺(aq) + 2NO₃¯(aq) —> 2AgCl(s) + Mg²⁺(aq) + NO₃¯(aq)
Cancel out the spectator ions (i.e Mg²⁺ and NO₃¯) to obtain the net ionic equation
2Cl¯(aq) + 2Ag⁺(aq) —> 2AgCl(s)

Answer:
Biphenyl
Explanation:
The reaction of bromo benzene with magnesium-ether solution yields a Grignard reagent.
The byproduct of this reaction is biphenyl. It is formed when two unreacted bromobenzene molecules are coupled together.
Hence, It is advised that the bromobenzene solution be added slowly to the magnesium-ether solution so that it isn't present in a high concentration, thus reducing the amount of biphenyl by-product formed.
Answer:
a. P
b. Br
c. Ag
d. Na
Explanation:
The Periodic Table says so
In general the inter- molecular attraction between particles of gases is much more smaller than those found in the particles of liquids. Because of this, the particles of gases are usually far apart from one another while the particles of liquid are closer together compares to that of gases.
