Propose a structure for an aromatic hydrocarbon, C10H14, that can form only one C10H13Cl product on substitution with chlorine.(Ignore the ortho, para-directing effects of the alkyl groups in answering this question. Consider only the number of non-equivalent hydrogens on the aromatic ring.)

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

High-pressure liquid chromatography (hplc) is a method used in chemistry and biochemistry to purify chemical substances. the pressures used in this procedure range from around 500 kilopascals (500,000 pa) to about 60,000 kpa (60,000,000 pa). it is often convenient to know the pressure in torr. if an hplc procedure is running at a pressure of 1.03×108 pa , what is its running pressure in torr?
