Correct Answer: D. 6.0 x 10⁵km

Explanation

Time = 1 x 4 x 10^-3sec

distance = velocity x time

= 3 x 10⁸ x 4 x 10^-3

= 6 x 10⁵km

Correct Answer: B) There will be a large increase in free energy.

Explanation

In this question, we are given that the reaction is exothermic and there is a great disorder. We need to understand what these terms mean and how they relate to free energy change in a reaction.

Anexothermic reaction is a reaction that releases heat to the surroundings. In such reactions, the energy of the products is less than the energy of the reactants, which means that the overall change in energy is negative (?H < 0).

Disorder in a reaction refers to the entropy change (?S). A great disorder implies that there is a large increase in entropy, which means that the products are more disordered than the reactants. A significant increase in entropy is associated with a positive value of ?S.

Now, let's consider the concept offree energy (?G), which determines the spontaneity of a reaction. The relationship between free energy, enthalpy, and entropy is given by the following equation:

\[\Delta G = \Delta H - T\Delta S\]

Where ?G is the free energy change, ?H is the enthalpy change, T is the temperature in Kelvin, and ?S is the entropy change. A negative value of ?G indicates a spontaneous reaction, while a positive value indicates a non-spontaneous reaction.

Since the reaction is exothermic (?H 0), the equation becomes:

This implies that there will be a large increase in free energy (?G > 0), which corresponds toOption B.

Correct Answer: C. Distillation

Explanation

Chlorine is one of the most commonly used disinfectants for water disinfection. Addition of Chlorine helps to kill certain bacteria and other microbes in tap water

Correct Answer: D) man to govern himself

Explanation

The first option says that politics is an act for states to control its destiny. This means that states use politics to control their own future. The second option says that politics is an act for man to create government. This means that people create governments through politics. The third option says that politics is to determine orders. This means that politics is used to make decisions about how things should be organized.

The correct answer is option D: man to govern himself. This means that politics is used to enable people to rule themselves. This is also known as self-governance or democracy. It means that people have the power to make decisions about how their country or community should be run.

It is important to understand the purpose of politics because it affects everyone's lives. Politics determines how resources are distributed, how laws are made and enforced, and how conflicts are resolved. Understanding politics helps people make informed decisions about who to vote for and what policies to support.

Overall, politics is an important aspect of modern society, and it is important to understand its purpose. The correct answer to the question is option D: man to govern himself.
