Combustion analysis of a compound known to contain just C, H, N, and O demonstrated that it is 46.21 wt% C, 9.02 wt% H, 13.74 wt% N, and, by difference, 100 46.21 9.02 13.74 31.03% O. This means that 100 g of unknown would contain 46.21 g of C, 9.02 g of H, and so on. Find the atomic ratio C:H:N:O and express it as the lowest reasonable integer ratio.
Chapter 14 — Aqueous Equilibria: Acids and Bases 1 I. Arrhenius Definition: A. Arrhenius acid — dissociates in water to give hydrogen ions (H ) B. Arrhenius base — dissociates in water to give hydroxide ions (OH ) Arrhenius definition does not account for basicity of NH or other bases without OH and C. only accounts for aqueous solutions II.Brønsted-Lowry Defintion: A. Brønsted-Lowry acid — anything that can donate a hydrogen ion (H ) 1. CH COOH, H SO , HCl 3 2 4 + B. Brønsted-Lowry bas— — anything that can accept a hydrogen ion (H ) 1. NH 3 CH C3O , HSO , SO4, H 4— — C. H is very reactive (3 O ) is the hydronium ion III.trong acids
