Salicaldehyde is formed by reimer Riemann reaction in which phenol and chloroform are heated together with sodium hydroxide or pottasium hydroxide yeild salicaldehyde.
C6H5OH+CH3Cl ----------> C7H6O2
KOH
It is also prepared by corresponding phenol by duff reaction.
Answer:
In the first combination neutralization takes place to give a salt. So, solution 'a' is neutral in nature.
In the solution 'c', both salts are resulted by the combination of weak base and strong acid. The combination of these salts suppresses the acidity.
In last combination basic nature is observed due to the presence of CN⁻ ions. Thus, the solution 'd' is basic in nature.
Out of the five given solutions, 0.0100 M in HF and 0.0100 M in KBr is most acidic. Therefore, solution 'b' is most acidic in nature.
Explanation:
KE = mv²/2
m=2*KE/v²
v=50 m/s
KE=500J
m=2*KE/v² =2*500/50²=1000/2500= 0.4 kg
Answer: The answer is 167
