Answer:
C₆H₅COOH Benzoic Acid
Explanation:
Here we are using the extraction method to separate benzoic acid from naphtalene in the ether solution by reacting it with the base sodium bicarbonate to produce the salt sodium benzoate ( naphtalene remains in the organic layer ) .
The sodium benzoate is completely soluble in the aqueous layer being a salt, and reacts with hydrochloric acid ( again an acid base reaction ) which precipitates the benzoic acid since the it is insoluble in water hence separating it.
Answer:
b
Explanation:
because it is moving so it has kinetic energy
Answer:
Coulomb's law describes the magnitude of the force between two charged particles.
Explanation:
Coulomb's Law states that:
The magnitude of force between two charged particles is directly proportional to the product of the charges of the two particles and inversely proportional to the square of the distance between the two particles.
The force between two likely charged particles is positive.
Likely charged particles repel each other.
The force between two oppositely charged particles is negative.
Unlikely charged particles attract each other.
