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

3. Some commercial baking powders contain a mixture of sodium bicarbonate (baking soda) and calcium dihydrogen phosphate. When the powder is moistened, carbon dioxide s is liberated and makes the batter or dough rise. Balance the equation for the following reaction. NaHCO Ca(H2PO4)2 ),-. Na2HPO4 + CaHPO4 + CO2 + H2O

A recipe for scones asks for 1.80 g of baking soda (sodium hydrogen carbonate). Upon heating at 180 °C at a pressure of 1.00 bar, baking soda decomposes as follows: 2 NaHCO3(s) + CO2(g) + Na2CO3(s) + H20(1) If the volume of the dough before baking (i.e. before the decomposition reaction takes place) is 668 ml, what will be the total volume of the scones after baking, in mL? Assume that the rising of the dough is only caused by...

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 (HC1), which the stomach secretes to help digest food. Drinking a glass of water containing dissolve NaHCO3 neutralizes excess HCl through this reaction: HCI(aq) NaHCO3(aq) → NaCl(aq) + H,O() + CO2(g) The CO2 gas produced is what makes you burp after drinking the...
