Secondary Alcohol is converted into corresponding Cyanohydrin in two steps;
Step 1: Oxidation of Sec. Alcohol: Secondary Alcohols when treated with Sodium Dichromate in acidic medium are converted into corresponding Ketone.
Step 2: Reduction of Ketone using HCN: Ketone is reduced to Cyaynohydrin when treated with CN nucleophile. A nucleophillic addition reaction takes place.
A strong electrolyte dissociates completely into its ions but in weak electrolyte only certain number of ions are dissociated so pH depends upon the dissociated ions.
Definition of pH
An evaluation of how basic a substance or solution is its pH is determined. pH is measured on a scale from 0 to 14. A pH value of 7 is considered to be neutral on this scale, which implies it is neither acidic nor basic. If the pH value is less than 7, it is considered to be acidic and if the pH value is greater than 7, it is considered to be basic.
pH < 7 for NH₃ and HClO₄ since the acid is strong acid and the base is weak base.
The pH value for NaOH and Benzoic acid is pH > 7, since the base is strong base and acid is a weak acid .
pH = 7 for HBr and KOH since both are strong acid and strong base
pH < 7 or pH > 7 since both are neutral.

Answer:
I don't know if you can directly prove it with evidence if you haven't observed it but you can maybe take an educated guess by the aftermath of it?
For example, you see a burnt log. At this time, people don't know what fire is. After we study the log, we could see that it takes extreme temperature in order to burn the log and that would help people see that there is a force like fire that can cause this. In a way, finding out that extreme temperatures burns stuff is another step closer to the discovery and proof of fire
I hope that makes sense
It would 3 because if you read it tells you the answer
Answer: 39.948 grams
Explanation:
The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Ar, or 39.948 grams
