What would be the product of triphenylbromomethane with water if it was reacted in acetone/methanol
Ligands approaching in a tetrahedral pattern cause some orbitals to be raised in energy. How many orbitals are on the lower energy level?
Orange juice can be modeled crudely as a misture of 8 g/L of citric acid (formally, 2-hydroxy-1,2,3-pro-panetircarboxylic acid; C6H8O7) and 1.6 g/L potassium ion. Find the equilibrium pH of orange juice
