Answer:
The temperature of the solute/solvent without any external effect would decrease.
Explanation:
As the bonding between the solute particles is really strong, therefore a large amount of energy is required to overcome these forces. So that the new bonding between the solute and solvent is created.
In order to achieve this, there will be a lot of energy required and that is through the heating process. So the solution will require energy so the solute will dissolve fully either by provision of external force i.e stirring or by heating.
Explanation:
<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
Weak acid is defined as the acid which does not get completely dissociated into its ions when dissolved in water. For Example: etc..
Strong acid is defined as the acid which gets completely dissociated into its ions when dissolved in water. For Example: etc..
Weak base is defined as the base which does not get completely dissociated into its ions when dissolved in water. For Example: etc..
Strong base is defined as the base which gets completely dissociated into its ions when dissolved in water. For Example: etc..
From the above information, it is clearly visible that the correct answer is Option c.
Answer: Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of solution = 0.338 M
= volume of solution = 25.7 ml
= molarity of solution = 0.155 M
= volume of solution = ?
= valency of = 1
= valency of = 1
Therefore, the volume of a 0.155 M potassium hydroxide solution is 56.0 ml
It is false that if a question is asking about an opinion, it can be answered with science.
<h3>What is opinion?</h3>
A personal belief or assumed that is not tested or backed up by evidence is described as an opinion.
A hypothesis is typically a claim based on some form of observation or evidence. Hypotheses must be testable and, once tested, evidence-supported.
Any question that is based on opinion cannot be answered by scientific reasonings as it is not evidence based.
Thus, the given statement is false.
