<span>The fossil fuels form from the buried remains of ancient organisms, </span>formed from the remains of dead plants and animals.
<span> These plants and animals that have been converted to crude oil, coal, natural
gas, or heavy oils by exposure to heat and pressure in the earth's
crust over hundreds of millions of years. So, three things that act on decaying organisms to help form fossil fuels are:
-pressure
-heat
-physical and chemical changes
People use fossil fuels products for transportation and heating, many power plants burn coal for heat to turn turbines that generate electrical energy. ...</span>
The answer is C. Because you need the sun to start your cycle which starts with water evaporation
a physical change that can be undone. A final substance can be converted back to the original substance without creating any new material. Freezing, melting, dissolving, boiling, evaporating and condensing are reversible changes.
Answer: The partial pressure of neon is 173 mmHg
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : 
=total pressure of gases = 490 mm Hg
= partial pressure of Helium = 215 mmHg
= partial pressure of argon = 102 mm Hg
= partial pressure of neon= ?
Thus partial pressure of neon is 173 mmHg
