Assume that we using a very nonpolar stationary phase in GC we can guess that elution times Butanol, II. Isopropanol, III. Ethanol.(Hint:polarity of alcohols increases with increasing for the four following analyte species can be ranked in terms of shortest to longest as:I. the number of carbon atoms).

A+b→2c when the reaction begins, the researcher records that the rate of reaction is such that 1 mole of a is consumed per minute. after making changes to the reaction, the researcher notes that 2 moles of a are consumed per minute. what change could the researcher have made to effect this change?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What four properties do all waves have in common
