Based on factors affecting solution formation;
- Strong solvent-solute intermolecular forces favors solution formation.
- Increase in entropy favours solution formation
- Decrease in enthalpy favours solution formation
<h3>What is a solution?</h3>
A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.
Factors that affect solution formation include:
- strength of intermolecular forces between solute and solvent
- entropy
- enthalpy
Strong solvent-solute intermolecular forces favors solution formation.
Increase in entropy favours solution formation
Decrease in enthalpy favours solution formation.

A substitution reaction has two steps, and doubling the concentration of the alkyl halide is found to double the reaction rate. This is a bimolecular SN2 reaction is a false statement.
<h3>What is substitution reaction?</h3>
Substitution reaction is a single step reaction in which one functional group is substitute by another functional group. An example is halogenation reactions, in which a functional group is replaced by a halogen.
Thus, the statement is false.

Answer:
D
Explanation:
--2 K (s) + __ H2SO3 (aq) --
-->
_K2SO3 (aq) + __H2
To balance this equation, all you need do is put a 2 in front of the K. The rest don't require any balancing coefficients.
Left
2 K
2 H
1 SO3
Right
K2
1 SO3
1 H2
It's balanced.
Anion means negatively charged ion.
Among Ar, K, Al and O, only O forms anion.
Hope this helps!
