Read the chemical equation. 2H2 + O2 → 2H2O Which of the following statements would be correct if one mole of hydrogen was used in this reaction? One mole of oxygen was used in this reaction. Two moles of oxygen were used in this reaction. One mole of water was produced from this reaction. Two moles of water were produced from this reaction.

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.

i just learnt this recently but i need to look through my notes again

the equation for synthesis of water is as follows;

here two moles of hydrogen are used with one mole of oxygen which gives one molecule of water as a product. but shana misinterpreted 2 moles as 2 grams in this equation.
