Acids and Bases
____ depends on how much solute dissolves in solution.
What is concentration?
What is time that it takes for half of the initial amount to undergo reaction.
What is a half-life?
Thermal (heat) transfer by the contact (touching) of two objects.
What is an conduction?
A process during which chemical bonds between atoms are broken and new ones are formed. Producing one or more different substances.
What is a chemical reaction?
When a chemical reaction is at equilibrium, the concentration of each reactant and the concentration of each product must be ____.
What is a constant?
Acidic compounds gives food a ___ taste.
What is sour?
The change in concentration of a reactant or a product per unit time
What is a reaction rate?
When two objects are at the same temperature.
What is thermal equilibrium?
The starting materials in a chemical reaction.
What is a reactant?
When the rate of the forwards reaction equals that of the backwards one. The concentrations are constant (not equal).
What is a dynamic equilibrium?
A substance that dissolves in water to produce Hydrogen (H+) ions
What is a acid?
A substance that initiates or accelerates a chemical reaction without itself being affected or consumed.
What is a catalyst?

What is first-order reaction?
The study of how heat moves.
What is thermodynamics.
A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.
What is an chemical equation?

what is raise to the power of the multiple?
What is the pH of water?
What is 7?
An unstable arrangement of atoms that exists momentarily at the peak of the activation-energy barrier; an intermediate or transitional structure formed during the course of a reaction.

Air cools as it escapes from a driver's compressed air tank. What kind of process is this?
What is adiabatic?
Tells how many atoms of an element are contained in one molecule or formula unit.
What is a subscript?
