A concentrated sulfuric acid solution is 74.0% H2SO4 by mass and has a density of 1.66 g/mL at 20°C. (MW of H2SO4 is 98.0 g/mol.) The molality of the H2SO4 solution is ?
The lab is synthesis of Methyl Red. The question is that diazonium salts cople with phenols in slightly alkaline solution. What effect does the PH of the solution have on reactivity of the phenol
Draw all possible stereoisomers for each of the following compounds. If no stereoisomers are possible, only draw one structure. (All hydrogen atoms are implied. If a chiral carbon atom is attached to a hydrogen atom, you should not show the hydrog..
The effective nuclear charge tends to decrease from left to right across any period of the periodic table. 3.Electrons in the 2s orbital feel a greater attraction to the nucleus than the 2p electrons and are therefore lower in energy. 4. Valence e..
