Answer:
The correct answer is option A, that is, the organic layer.
Explanation:
One knows that non-polar solvent dissolves non-polar substances and the polar solvent dissolves polar substances, that is, like dissolved like. The toluic acid or benzoic acid refers to the carboxylic acids, which are non-polar or are very less polar in characteristics.
Therefore, they possess the tendency to remain in the organic solvent, which is non-polar like diethyl ether. The toluic acid's or benzoic acid's non-polar characteristic is because of the existence of huge hydrophobic rings of benzene. Hence, the correct answer is option A, that is, the organic layer.
When the parts of the atoms are connected such as the electrons are connected around the molecules which are made up of nuetrons and protons. Calcium is the same way
Answer:
B. Inertia resist changes to the state of motion of a body.
Explanation:
The force of inertia is an inherent property of matter in which it allows a body to resist changes to the state of motion of the body.
According to Newton's first law of motion "a body will remain at rest or in constant motion unless if an external force acts on it".
This is the law inertia.
- The ability of a body to resist changes to the motion of the body is its inertia.
- Therefore, the correct choice is B.
