Match each statement in the left column of the table below with a compound on the right. In your answer, write the name of the matching compound against the number of the statement, eg. a) Hg Note that each compound must be matched with only one statement. If a compound can be matched with more than one statement (or vice versa), it is up to you to find the BEST match. a) A metal that is in the liquid phase at room Sio2 temperature. CO2 b) A compound that forms a network solid KNO3 composed of covalently bonded atoms. c) A gas that will dissolve in water due to Poly-ethylene (a plastic) dipole – induced dipole forces. Graphite d) The solid-liquid equilibrium line on the H20 phase diagram of this compound has a negative slope. NH3 e) A solid substance at STP, in which the Hg particles are held together by induced 12 dipole - induced dipole forces. f) A substance that will dissolve in water due to hydrogen bonding. 8) A covalent network solid that has good electrical conductivity. h) An…
