An aqueous solution containing 1 mole of isoleucine and 1 mole of glutamic acid in water is separated using a craig extraction . the mobile phase is n-butyl alcohol and the stationary phase is water. there are 60 tubes . each tube contains 10 milliters of n-butyl alcohol and 40 milliters of water. k glutamic acid =5, k glycine =2, k isoleucine= 0.5 which single tube contains the maximum amount of glutamic acid? which single tube contains the maximum amount of isoleucine? which single tube contains the maximum amount of glycine?

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

Achemical reaction (also known as a chemical change) produces substances that are chemically different from the starting materials. an example of a chemical reaction is the formation of water from hydrogen and oxygen gas. in a physical change, a substance changes its physical appearance but not its chemical identity. an example of physical change is the formation of liquid water from solid water, a familiar process called melting. physically, liquid water looks very different from solid water (ice) but the chemical identity, water, is the same for both. which of following changes that affect the composition of our atmosphere involve physical changes and which involve chemical reactions? oxygen gas changes to ozone during thunderstorms carbon dioxide is produced by the combustion of gasoline in an automobile engine. when coal, oil, and natural gas are decomposed in landsills they produce methane gas. freezing rain develops when a warm air mass overrides a cold air mass. fog forms from water vapor when the temperature drops below the dew point

How many moles of gas are present if p=11 atm, v=12l, t=185k?
