A balanced chemical reaction is shown below. C5H12 + 8O2 ‹ 5CO2 + 6H2O If 3 moles of C5H12 are reacted completely, how many moles of wafer are formed?

18moles of H20

Explanation:

C5H12 + 8O2 —> 5CO2 + 6H2O

From the balanced equation,

1mole of C5H12 were consumed to produce 6moles of H2O.

Therefore, if 3 moles of C5H12 were consumed, it will produce = 3 x 6 = 18moles of H20

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
