1.00 L of a solution containing 0.0500 mole of CH3COOH and
0.100 mole of CH3COONa. Ignore the autoionization of water for the
purposes of this problem. The Ka of CH3COOH equals 1.77 x 10-5.

Imagine that you have produced several versions of lactase, each of which differs from normal lactase by a single amino acid. describe a test that could indirectly determine which of the versions significantly alters the three-dimensional shape of the lactase protein.

An experimental procedure requires a 10 ml of acid to be dissolved

An excess of lithium oxide undergoes a synthesis reaction with water to produce lithium hydroxide li2o+h2o→2lioh if 1.05 g of water reacted, what is the theoretical yield of lithium hydroxide? a) 5.83 x 10–2 g lioh b) 1.17 x 10–1 g lioh c) 2.79 x 100 g lioh d) 1.40 x 100 g lioh
