Calcium dihydrogen phosphate, Ca(H2PO4)2, and sodium hydrogen carbonate, NaHCO3, are ingredients of baking powder that react with each other to produce CO2, which causes dough or batter to rise:

Ca(H2PO4)2(s) + NaHCO3(s) → CO2(g) + H2O(g) + CaHPO4(s) + Na2HPO4(s)[unbalanced]
If the baking powder contains 31.0% NaHCO3 and 35.0% Ca(H2PO4)2 by mass:

(a) How many moles of CO2 are produced from 6.85 gof baking powder?

____mol CO2

(b) If 1 mol of CO2 occupies 37.0 L at 350°F (a typical baking temperature), what volume of CO2 is produced from 6.85 g of baking powder?

____L

Sodium hydrogen carbonate NaHCO3, also known as sodium bicarbonate or "baking soda", can be used to relieve acid indigestion. Acid indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid HCl, which the stomach secretes to help digest food. Drinking a glass of water containing dissolved NaHCO3 neutralizes excess HCl through this reaction: HCl(aq) +NaHCO3(aq) →NaCl(aq) +H2O(l) +CO2(g) The CO2 gas produced is what makes you burp after drinking the solution. Suppose the...

Calcium hydride, CaH2, reacts with water to form hydrogen gas: CaH2(s)+2H2O(l)→Ca(OH)2(aq)+2H2(g) This reaction is sometimes used to inflate life rafts, weather balloons, and the like, where a simple, compact means of generating H2 is desired. Part A How many grams of CaH2 are needed to generate 146 L of H2 gas if the pressure of H2 is 824 torr at 22 ∘C? The metabolic oxidation of glucose, C6H12O6, in our bodies produces CO2, which is expelled from our lungs as...
