<h2>ANSWER: </h2><h2>_____________________________________</h2><h2>TYPES OF CHEMICAL REACTIONS:</h2>
There are two types of Reactions,
<h3>
Endothermic Reactions: </h3>
Endothermic reactions are the type chemical reaction in which the reactants absorb heat energy from the surroundings. The energy of reactants is more than the energy of product
<h3>Exothermic Reactions: </h3>
Exothermic reactions are the type of chemical reactions in which release of energy takes place in the form of heat or light. In an exothermic reaction, energy is released. The energy of the products is less than the energy of the reactants.
<h2>_____________________________________</h2><h3 /><h3>In Question number 5,</h3>
The key word is "RELEASE". The reaction in which energy is released is the Exothermic reaction thus the Option B that is EXOTHERMIC REACTION is correct.
<h2>_____________________________________</h2><h3 /><h3>In Question number 6</h3>
It is asking that which process stores the energy that means it is asking which process undergoes endothermic reaction. The answer is Option C that is PHOTOSYNTHESIS is correct.
<h3>__________________________________________________</h3><h3>WHY PHOTOSYNTHESIS?</h3>
Because, sunlight is being absorbed during the reaction and according to the definition of endothermic reaction if heat is being absorbed it is termed as an endothermic reaction.

Answer:

Explanation:
To calculate the period we need the formula:

Where
is the radius of the moon,
is the universal constant of gravitation and
is the mass of mars.
The period of Phobos:

The period of Deimos:

The ratio of the period of Phobos and Deimos:


Most terms get canceled and we have:

According to the problem

so the ratio will be:
≈ 
the ratio of the period of revolution of Phobos to that of Deimos is 0.2528
