Solar energy or energy from the sun is contained in
Answers
The solar energy is generated in the inner core of sun by nuclear fusion where hydrogen isotopes fuse together to form helium nuclei. This process is associated with the release of greater amount of energy.
What is nuclear fusion ?
Nuclear fusion is the process of fusing of two light nuclei to form a heavy nuclei. Whereas, breaking of a heavy unstable radioactive isotope is called nuclear fission. Both nuclear processes release tremendous energy.
The source of heat and light energy in sun and other stars is nuclear fusion in their core. Sun and stars are abundant in hydrogen gas. One protons and deuteron fuses together to form a helium nuclei.
This process repeats for major part of the hydrogen gas present in stars make them globes of fire and heat. Fusion takes place in the inner core of these stars. That is inside the chromosphere.

Option B, fragile, is the right answer.
The Permafrost soil (Gelisol) are found very harsh and cold weather such as Arctic and Antarctic. The Gelisol are simply corroded soils, fragile and their finding near the extreme ice covers presents them valuable indicators of the early symbols of global warming. Permafrost in these soils found within two meters of the surface of the soil.

We have,
Atomic mass = no. of protons + no. of neutrons
Now, we know, protons never change.....so the only thing that changes is neutrons if we want different atomic mass.
Soooooooo,
The answer is "D. A form of an atom with a different number of neutrons"
The answer is not A. because same element with different number of electron is ion.
The answer is not B. because if it has different number of proton....it is going to be a different element. Just like our fingerprints, we can say that protons are fingerprints of element. No. of protons never change.
The answer is not C. because again talking about electrons.
Answer:
D. A form of an atom with a different number of neutrons.
Explanation:
An Isotope has an equal number of protons but different numbers of neutrons in their nuclei.
Hope it helped!

Answer: The chemical species formed in a chemical reaction are products.
Explanation:
In a chemical equation, the chemical species are called as reactants or products.
Reactants are defined as the chemical species that react in the reaction and are written on the left side of the reaction arrow.
Products are defined as the chemical species that are produced in the reaction and are written on the right side of the reaction arrow.
For Example: Formation of water from hydrogen and oxygen gases, the equation follows:
The chemical species are termed as reactants and
is termed as products.
Hence, the chemical species formed in a chemical reaction are products.
