The questions are not all of equal value or points. There are 33 questions altogether. A student finds that 15.20 g of nitrogen will react with 17.37 g, 34.74 g, or 43.43 g of oxygen to form three different compounds. Glycerol, C3H8O3, is a substance used extensively in the manufacturer of cosmetics, foodstuffs, antifreeze, and plastics. Calculate the molarity of a solution of glycerol made by dissolving 50.000 mL of glycerol at 15 C in enough water to make 250.00 mL of solution.
Some sulfuric acid is spilled on a lab bench.
It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. Use Lewis symbols to represent the reaction that occurs between Al and F atoms. A pure sample of one of these substances is found experimentally to have a dipole moment of zero. The carbon atom in CH4 can not participate in multiple bonding, whereas that in formaldehyde, H2CO, does. Explain this observation by using the hybridization at the carbon atom.
