Answer: Option (E) is the correct answer.
Explanation:
Since, the conductor is hollow which means that it is opened on both the ends. Hence, when a small uncharged metal ball is passed through it with the help of a silk thread then due to the presence of this insulating thread the ball will not come directly in contact with the charged rod.
As a result, there will occur no formation of opposite charge on the metal ball. Therefore, the ball will remain uncharged in nature.
Thus, we can conclude that after the given ball is removed, it will have no appreciable charge.
Answer:
B) Florine
Explanation:
Thus, fluorine is the most electronegative element.

Answer:
false
Explanation:
when heat is added to atoms, the molecules vibrate more quickly, because it increases the heat energy, which in turn, increases the particle movement
A. Bin 3
<span>B. Bin 1 Nitrogen has a smaller molecular weight and will effuse at a faster rate. </span>
<span>C. Bin 3. If the gases are at the same temperature, they have the same average kinetic energy. </span>
<span>D. Bin 1. Nitrogen has a greater average velocity since it is a lighter gas.</span>
Option (C) is the correct answer.
In the chemical reaction, reactants are the starting elements or compounds which will chemically react and will form the products. Reactants are only present on the left hand side of the reaction and products are present on the right hand side of the reaction.
Reactants present in the reaction is completely used up in the reaction to form products implies no traces of reactants will be present in the product side.
For example:
Here, hydrogen and oxygen are the reactants whereas water is the product (new substance). Hydrogen reacts with oxygen and form water i.e. hydrogen and oxygen is completely used up in the reaction to form new substance i.e. water.
Hence, substances that are used up in a reaction is known as reactants of the reaction.
