Each of the thermometers shows a different temperature scale. The thermometer on top
measures temperature in Celsius degrees. The
thermometer on the bottom measures temperature in Fahrenheit degrees. The
thermometers are placed so that the freezing point of water is even on each scale as a reference. The freezing point of water is 32 degrees F. If the boiling point of water is 212 degrees F, what is the boiling point of water in
degrees C (Celsius)?

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.
