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? Ammonium nitrate (NH4NO3). Ammonium sulfate (NH4)2SO4. Ammonium chloride (NH4Cl). Ammonium carbonate (NH4)2C...

Acidic solution - A solution in which the concentration of H3O+ is greater than the concentration of OH- Also, a solution in which pH is less than 7. Anions - negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons). Arrhenius base - increases the concentration of OH- ions. Atom - An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atom...
