30 ! which of these is a benefit of fuel cell cars? fuel cell cars are inexpensive. hydrogen fuel can be stored safely. fuel cell cars do not release greenhouse gases. hydrogen fuel can be distributed easily.

Fuel cell cars do not emit green house gases.

Explanation:

The fuel cells involve the production of electricity through the electrochemical   reaction between hydrogen and an oxidizing agent. Normally, oxygen is used.

Reaction at the anode: 2H₂ + 2O₂− → 2H₂O + 4e−

Reaction at the cathode: O₂ + 4e− → 2O²⁻

Overall Cell Reaction: 2H₂ + O₂ → 2H₂O

The only byproduct is water vapor which is easily condensed into water. This means that the cells are environmentally friendly.

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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.
