A 0.4230-g sample of impure sodium nitrate was heated, converting all the sodium nitrate to 0.2864 g of sodium nitrite and oxygen gas. Determine the percent of sodium nitrate in the original sample.
CHPATER 9 SUBSTITUTIOS AND β-ELIMINATIONS Nucleophilic Substitutions - You have a Lewis Base (electron pair donor). - Reacts at a carbon (at the Lewis acid) where there is a leaving group being pushed off o Lewis Acid is where substitution is occurring - You cannot have the Lewis base form a bond and then the leaving group breaks off because that would mean carbon has 5 bonds for a moment, which is not possible - Two ways: 1) You can have the Lewis base come in and push off the leaving group simultaneously (S 2) N a.
