Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. The energy of wave is 2.08×10⁻¹⁵J.
What is electromagnetic wave?
Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave .There is a relation between energy of wave. frequency of wave
Mathematically,
E=hv
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
v= frequency of wave
substituting the given values
E= 6.67×10⁻³⁴js×3.12 x 10¹⁸ s⁻¹
E= 2.08×10⁻¹⁵J
Therefore the energy of wave is 2.08×10⁻¹⁵J.

Answer : 3 substance will have 3 mole ratios to be written for a chemical reaction.
Explanation : The mole ratio can be defined as the ratio between the amounts in moles of any two or more compounds involved in a chemical reaction.
It can be determined by comparing the coefficients the formulas of a balanced chemical equation. It is also known as the molar ratio or mole-to-mole ratio.
Hence, when 3 substances are involved in a chemical reaction 3 mole ratios can be written for it.

the number of moles of CaCl₂ present - 12 mol
Volume of solution - 3 L
Therefore if 3 L contains 12 mol of CaCl₂
then 1 L of CaCl₂ contains -
Therefore molarity of CaCl₂ is 4 M

Answer:
Corona
Explanation:
The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.
