Answer:
Explanation:
It is necessary to run TLC in a closed container and have the interior saturated with the solvent vapor to ensure maximum resolution between components and to prevent solvent evaporating off. If the solvent evaporates off, the Rf value would be lower than the expected value.
Answer a is the correct one
Answer:
False
Explanation:
The force of gravity is not only determined by the mass of the two objects but also the distance.
The law of universal gravitation states the product of the masses is directly proportional to the gravitational force, but it is also indirectly proportional to the square of the distance between them.
In other words, the greater the masses of each the greater the gravitational force, but the greater the distance between the two, the weaker the gravitational force.
