use %composition given to calculate emperical 4mular
<span>Like many plants, most species of grass produce a bright pigment called chlorophyll. Chlorophyll absorbs blue light (high energy, short wavelengths) and red light (low energy, longer wavelengths) well, but mostly reflects green light, which accounts for your lawn's color.
</span>sky<span> is </span>blue<span> because molecules in the air scatter </span>blue<span> light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colors because the </span>blue<span> light has been scattered out and away from the line of sight.

Hope this Helped!
When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the color of the object in that light. For example, a blue object absorbs all the colors of the spectrum except blue, it reflects blue light. hope this can help.
Answer:
The answer is: CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Explanation:
Boiling point refers to the temperature at which the pressure exerted by the surrounding on the liquid is equal to the vapor pressure of the liquid. The boiling point increases as the molar mass of the substance increases.
Since the molar mass increases in the order:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Therefore, the order of increasing boiling point:
CH₄ < CH₃OH < CH₃CH₂OH < HOCH₂CH₂OH
Answer:
Explanation:
Writing electronic configuration of any element you should know atomic number of that element ,
and also electrons are filling according to their energy level and first electron is filled in the lower energy orbital
and it follows n+1 rule if n+1 is same for two orbital electron will go first in the lowest value of n.
writing electronic configuration of ion can be done like first for their neutral atom and then add or remove electron it will make things easy because there are also some eception case their you may do wrong.
remove three electron from outer most shell of AU
