PbS + 2PbO → 3Pb + SO2 a. Balance the equation. b. How many moles of Pb will form from 17 moles of PbO (excess PbS)? 57.33g PbO x 1 mole of PbO/ c. How many moles of PbO are needed to make 27.3 moles of SO2 (excess PbS)? d. Give 17.6 moles of PbS and 36 moles of PbO, which is the limiting reactant?

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.
