The initial state of a quantity of monatomic ideal gas is p = 1 atm, v = 1 liter, and t = 373 k. the gas is isothermally expanded to a volume of 2 liters and is then cooled at constant pressure to the volume v. this volume is such that a reversible adiabatic compression to a pressure of 1 atm returns the system to its initial state. all of the changes of state are conducted reversibly. calculate the value of v and the total work done on or by the gas.

Which form of relativism states that people rely on their own standards of right and wrong when making a decision?

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.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
