Which best describes the path of solar radiation? from the surface of the Earth to the Sun, where it is absorbed from the Sun to the surface of the Earth, where it is absorbed or reflected from the surface of the Earth to the Sun, where it is absorbed or reflected from the Sun to the surface of the Earth, where it is reflected

from the Sun to the surface of the Earth, where it is absorbed or reflected

Explanation:

The solar radiation that emerges out of the sun and that reaches the surface of the Earth is sunlight. There are numerous constituents and particles present in the atmosphere that absorbs the solar radiation. These radiations are weakened by these constituents. Later, these radiations gets scattered in the atmosphere. Some amount of he solar radiation that reaches the Earth's surface is absorbed and some is reflected back.

the answer is c

tell me if wrong

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
