Rinsing the burette with distilled water prior to filling it up with the titrant.O b. Adding 100mL of distilled water instead of 50mL to the vinegar sample.O c. Titrating duplicate trials of soda samples within a 30-minute interval.O d. Reusing an uncleaned Erlenmeyer flask for the second trial of titration.2.Which of the following is/are TRUE about equivalence and end points?I. The end point of a titration is reached when the titrant and analyte arestoichiometrically equal.II. When you are titrating a strong or weak acid with a strong base, the end point willalways be faint pink using a phenolphthalein indicator.III. When you are titrating a strong or weak acid with a strong base, the volume needed toreach the end point will always be lower than that of the equivalence point.O a. Tand IIIO b. III onlyO c.

Gas Baron, the new SUV from US motors, features a 30 gallon (113.4 L) gas tank. assuming complete combustion and a molecular formula of C8H18 for gasoline, how many L of air are consumed per tank of gasoline. recall that air is 21% oxygen and assume a density of 0.78g/ML for gasoline.
A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of methyl acetate, chloroform, ethanolamine, diethylamine, and tetrahydrofuran. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml 1.5 g ml 1 -1 1.0 g ml 1 0.71 g ml 0.89 g ml. Next, the chemist measures the volume of the unknown liquid as 1005. cm' and the mass of the unknown liquid as 1.49 kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the data above, is it possible to Identify the liquid? If it is possible to identify the liquid, do so. 0 gml. yes no methyl acetate chloroform ethanolamine…

Even though cement and bread are not substances, they can help you to understand these concepts: Whatever you do to volume affects mass the same way. Whatever you do to mass affects volume the same way. If you have half as much of a material, you would expect the volume of the material to also be half as much. If you have twice as much of the material, you would expect its volume to also be twice as much. Substances, which you know are always the same throughout, will follow this rule. This relationship between mass and volume will stay the same for any substance, no matter how much of that substance you can sample and measure in the classroom. Why is this principle about the relationship between mass and volume always true of substances, but not always true of mixtures?
