Solid sodium hydrogen carbonate, NaHCO3, decomposes on heating according to the equation: 2 NaHCO3(s) <--> Na2CO3(s) + H2O(g) + CO2(g) A sample of 1.00 x 102 grams of solid NaHCO3 was placed in a previously evacuated rigid 5.00-liter container and heated to 160 0C. Some of the original solid remained and the total pressure in the container was 7.76 atmospheres when equilibrium was reached. Calculate the number of moles of H2O(g) present at equilibrium. How many grams of the...

At high temperatures, sodium bicarbonate is converted quantitatively to sodium carbonate, producing water and carbon dioxide. Heating a 1.7184 g sample of impure NaHCO3 produces 0.196 grams of CO2. Determine the mass percent of sodium bicarbonate in the original mixture. (Assume the impurities do not decompose when heated.)

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. Add indigestion is the burning sensation you get in your stomach when it contains too much hydrochloric acid (HCI) which the stomach secretes to help digest food. Drinking a das of water containing dissolved NaHCO, neutralizes excess HCl through this reaction HCl(aq) + NaHCO,(a) - NaCl(aq) + H,000 + CO2(0) The Co, gas produced is what makes you burp after drinking...
