Cooks use baking soda to make cakes light and fluffy. you might have used baking soda yourself. baking soda is nahco3. a 0.1 m solution of baking soda in water has a [h+] of about 4.0 × 10–9. (you may prefer to think of the hydronium ion concentration, [h3o+], as 4.0 × 10–9.) write the formula for the calculation of ph, and then show each step as you calculate the ph of a 0.1 m solution of baking soda.

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.
