Consider the following molecules with trigonal planar geometry. carbonate (co32−) and nitrate (no3−) both exhibit resonance, whereas phosgene (cocl2) does not. given the information in the transition, and ignoring the simulation, predict the bond angles for each of the molecules in accordance to whether or not they exhibit resonance. drag the appropriate labels to their respective targets. view available hint(s)\

See explanation.

Explanation:

Carbonate and Nitrate: during double resonance the double bond revolves around each oxygen. This creates an atmosphere equal to each O-C-O link, then all 1200.

Phosgene: being that the atmosphere changes for each atom the bond angle should be 120, but a deviation occurs, since oxygen is more electronegative than Cl and O, so it is doubly linked. The Cl-C-O bond increases because the O and Cl repel each other, and a 124.3 bond angle is created between Cl-C-O, decreasing the Cl-C-Cl bond angle to 111.4 degrees.

See the result in the attached graph.

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
