The volume of a gas held at constant temperature varies indirectly as the pressure of the gas. if the volume of a gas is 1200 cubic centimeters when the pressure is 400 millimeters of mercury, what is the volume, v, when the pressure is 500 millimeters of mercury?

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

When the volume and number of particles of a gas are constant which of the following is also constant

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.
