A note on the door of the cabinet says the cabinet is used to store bottles of pentane, dimethyl sulfoxide, acetone, methyl acetate, and chloroform. 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 density 0.63 mL pentane db dimethyl sulfoxide 1.1 0.79 acetone 0.93 mL methyl acetate 1.5 chloroform 3 Next, the chemist measures the volume of the unknown liquid as 1797.…

E O CHEMICAL REACTIONS 0/3 Cameron V Solving for a reactant in solution One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with tin(II) chloride, which would react with silver nitrate solution like this: SnCl,(aq) + 2 AgNO,(aq) → 2 AgCl(s) + Sn(NO,),(aq) The chemist adds 23.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 6.8 of silver…

His Dalton's Atomic Theory ideas form the atomic theory of matter. Here are his ideas. • All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. • All atoms of the same elements are alike. (One Atoms of element X Atoms of ement Y Compound of elemeite XandY atom of oxygenis like another atom of oxygen.) • Atoms of different elements are different. (An atom of oxygen is different from an atom of hydrogen.) • Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios. For example, water is a compound made up of 2 atoms of 1. What is the name of John Dalton's theory? 2. What are elements made of? 3. An atom of hydrogen and an atom of carbon are 4.
