In this week's experiment, you prepared sodium hydrogen carbonate, commonly called baking soda. Next week, you will analyze your product. One way you will use is to convert NaHCO3 (MW = 84.0) to Na2CO3 (MW = 106) by heating the sample gently. Calculate the percent yield: Mass of crucible after cleaning: 13.4422g.
How many ATPs are synthesized for every cytoplasmic NADH that participates in the glycerophosphate shuttle in insect flight muscle?
Benzoic acid reactis with sodium bicarbonate (NaHCO3) causing the benzoic acid to take up the sodium on one of the oxygen molecule and making HCO2OH
A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is.
Protein X contains 16.78% nitrogen. A 0.4100 mL aliquot of protein X solution was digested, and the liberated NH3 was distilled into 10.00 mL of 0.02260 M HCl. Unreacted HCl required 3.07 mL of 0.01960 M NaOH for complete titration.
