The two parts of a solution are a Solute and the other one is a Solvent. The Solute is the substance that dissolves, and the Solvent is the majority of the solution.
Salt (not table salt!) is formed when an acid reacts with a base. Salt is a compound. Water is also produced as a by-product of this reaction.
Answer and Explanation:
Calorie is the unit of heat energy . There are 2 units with the same name 'calorie' which is widely used.
'The amount of heat energy required to increase the temperature of 1 gram of water by mass by 
or 1 K is known as small calorie or gram calorie'.
Another one is large calorie which can be defined as :
'The amount of heat energy required to make arise in temperature of water 1 kg by mass by or 1 K is known as large calorie or kilcalorie and is represented as Cal or kcal'.
After the adoption of SI system, thee units of the metric system cal, C or kilocal are considered deprecated or obsolete with the SI unit for heat energy as 'joule or J'
1 cal = 4.184 J
1C or 1 kilocal = 4184 J
Calorimeter constant:
Calorimeter constant, represented as '
' is used to quantify the heat capacity or the amount of heat of a calorimeter.
It can be calculated by ther given formula:
where,
= corresponding temperature change
= enthalpy change
Its unit is J/K or J/1^{\circ}C[/tex] which can be convertyed to cal/1^{\circ}C[/tex] by dividing the calorimeter constant by 4.184 or 4184 accordingly.
The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.
<h3>What is substitution product?</h3>
Substitution product is a product that is gotten from a reaction in which a group of reactant is replaced by another group in the reaction.
Therefore,The substitution product that is suppose to be favoured is The product with retention of configuration is expected to predominate slightly, because the leaving group blocks the nucleophile.

Thus, a sodium hydroxide solution has a greater OH– concentration than the same concentration solution of NH3. At the same concentrations, the pH of the NaOH solution is greater (more basic) than the NH3 solution.
