In a tautomeric shift . Multiple Choice hydrogen atoms move to form a base with altered hydrogen properties final bonding of nucleotides remains unchanged carbon atoms move to form a base with altered properties it is always adenine that is changed adenine is changed so it can no longer form base pairs

Which substance is a steroid? cholesterol fatty acid monosaccharide trans fat

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .

From the choices provided below, list the reagent(s) in order that will react with cyclopentanone to form the compound shown below.
