18. A) Self-contained self-rescue breathing devices convert CO, to O2 according to the following reaction: 4 KO, (s) + 2 CO, (g) → 2 K,CO; (s) + 3 0; (g) How many grams of KO, are nceded to produce 100.0 L of O; at 20 °C and 1 atm? (Molar mass of KO, is 71.1 g/mol) B) A gascous mixture made from 6.00 g O, and 9.00 g of CH, is placed in 15.0 L vessel at 0 C. What is the total pressure in the vessel? (Molar Mass of O, is 32.0 g/mole and CH, is 16.0 g/mole)

The zinc(II) ion behaves as a Lewis acid. It is found in an enzyme called carboxypeptidase A. This enzyme catalyzed the hydrolysis of C-terminal peptide bonds of proteins. The zinc ion will accept the lone pair of electrons on the oxygen in the peptide linkage. Explain why this Lewis acid behavior would make the carbon atom more susceptible to reaction.
