- Fumaric acid is quite common in the plant world and is added to many foods due to its acidity and fruity flavor. It has a molar mass of 116.07 g/mol and a formula of C4H4O4. A solution of sodium hydroxide is used to determine the molarity of a fumaric acid acid solution before it is used to prepare some sour gummi worms. C4H4O4(aq) + 2NaOH(aq) --> Na2C4H2O4(aq) +2 H2O(l) Calculate the Molarity of the fumaric acid if 32.08 mL of 0.09973 M NaOH was used to neutralized 75.00 mL of fumaric acid solution. Assume the fumaric acid is acting as a strong electrolyte acid in this reaction. (It is a weak acid, but a very strong weak electrolyte) Fumaric acid is quite common in the plant world and is added to many foods due to its acidity and fruity flavor.

If 0.150 g of potassium cyanide reacts with an excess of HCl (i.e., enough HCl to completely react away all of the KCN), how many grams of hydrogen cyanide gas can theoretically be produced?One of the challenges astronauts face is in space travel is the build-up of carbon dioxide in their spacecraft. The average human exhales about 42.0 g of carbon dioxide per hour. One method to remove the excess carbon dioxide from the air is using solid lithium hydroxide: CO2(g) + 2 LiOH(s) → Li2CO3(2) + H2O(l) If a typical cannister of LiOH contains 750.0 g, how many hours will it last for one person before it has to be replaced?

- Natural waters often contains relatively high levels of calcium ion, Ca2+, and hydrogen carbonate ion (bicarbonate), HCO3, from the leaching of minerals into the water. When such water is used commercially or in the home, heating of the water leads to the formation of solid calcium carbonate, CaCO3, which forms a deposit ('scale') on the interior of boilers, pipes, and other plumbing fixtures. Ca(HCO3)2(aq) --> CaCO3(s) + CO2(g) + H2O(l) If a sample of well water contains 2.0 X 10-3 mg of Ca(HCO3)2 per milliliter, what mass of CaCo3 scale would 1.0ml of this water be capable of depositing?An experiment using the reaction below produces 23.26 grams of chlorine gas (Cl2).
