clastic, organic, and chemical
The chromosphere is the third and the lowermost layer of the sun and appears bright red. This chromosphere region is visible only during the total solar eclipse. Thus, option B is correct.
<h3>What is a solar eclipse?</h3>
A total solar eclipse is an event in which the new moon is in between the Earth and the Sun resulting in the formation of the dark shadow on the Earth's surface.
During this eclipse, the chromosphere region of the sun is visible as it was hidden by the photosphere before the eclipse. It shines bright red and yellow as the spectral line of the hydrogen alpha is emitted.
Therefore, option B. the chromosphere region is visible only during the total solar eclipse.

Answer:
The mole and atonmicity of both the gases are different, the number of atoms is not same.
Explanation:
The number of atoms in a molecule (compound) depends on mole number and atomicity.
↬ Mole of 100 g H₂ = 100g ÷ 2u = 50 mole
∴Number of atoms in 100 g H₂
= 2 x 50 x 6.022 × 10²³
= 6.022 x 10²⁴ atoms
↬ Mole of 100 g He = 100g ÷ 4u = 25 mole
∴ Number of atoms in 100 g He
= 1 × 25 × 6.022 × 10²³
= 150.55 × 10²³
= 1.5055 x 10²⁵ atoms
Thus, The mole and atonmicity of both the gases are different, the number of atoms is not same.

The ratio of phosphorous to oxygen is 2:5
<u>Explanation</u>:
- In a compound P2O5, the ratio of phosphorous to oxygen atoms is 2:5. Because there are two phosphorous atoms and five oxygen atoms. Both combined are called a P2O5.
- The elements of phosphorous and oxygen are added to P2O5. So P2O5 is called as phosphorous pentoxide. The element phosphorous will be added to oxygen and it will form a chemical reaction.
- This includes a change in the energy of P2O5. So the new energy will be produced.
