TBR- Acid and Base Exam Questions & Answers 2024 if the acid strength goes up, which one decrease or increase Ka, PKa, conjugate base strength, kb, pKb - ANSWER-As acid strength goes up, Ka goes up, pKa goes down, conjugate base strength goes down, Kb goes down, pKb goes up what determines the acidity when you compare molecules within the same group? what about when they're in the same period? how does the number of excess oxygen relates to the acidity of the compound, for example betwe...

Cumulative Exam Review Questions and Answers Graded A+ What explains the effect observed when gas molecules move at a slower rate? The temperature drops because the average kinetic energy diminishes. The volume of the gas increases. The pressure of the gas remains constant. The density of the gas increases. Which salt forms when ammonium hydroxide reacts with nitric acid?
