This state of matter has a definite shape and a definite volume.
What is solid?
The fundamental SI unit used to measure the amount of a chemical substance
What is a mole?
This fundamental gas law states that the volume of a gas at a constant temperature is inversely proportional to its pressure

This formula is used to calculate the volume or concentration of a diluted solution.
This factor affects the reaction rate of gases by bringing particles closer together, increasing collision frequency
What is pressure?
This is the equation to calculate the pH of a solution
What is pH = -log[H+]?
The phase change that occurs when a solid turns into a liquid
What is melt?
In the reaction N2 + 3H2 -> 2NH3), this is the mole ratio of Nitrogen (N2) to Ammonia (NH3)
What is 1:2?
This is the constant (R) used in the Ideal Gas Law (PV = nRT) when pressure is in atmospheres (atm) and volume is in liters (L).

What is first order?
If the pH of a solution is 9, this is the pOH
What is 5?
The scientific term for when a solid transitions directly into a gas without melting first
What is sublimation
The maximum amount of product that can possibly be created in a perfect chemical reaction.
What is theoretical yield?
This abbreviation stands for the standard temperature and pressure conditions defined in chemistry
What is STP?
