TermDefinition
chemical equations A combination of chemical formulas and symbols that models a chemical reaction.
chemical equilibrium The state that occurs when forward and reverse reactions each happen at the same rate.
chemical reaction A process that rearranges the atoms in one or more substances into one or more new substances.
coefficient A number placed in front of a chemical formula within a chemical equation that shows how many units of a reactant or product are needed to balance the chemical equation.
collision model The model that states that for a reaction to occur, the reactant particles must collide with each other, with the proper alignment, and with enough energy.
combustion An exothermic chemical reaction in which a fuel reacts with oxygen.
decomposition reaction A chemical reaction in which a single reactant breaks down into two or more products.
double-replacement reactions A chemical reaction in which two ionic compounds swap cations or anions with each other; also known as double-displacement reaction.
endothermic reactions A chemical reaction that absorbs more thermal energy than it releases.
exothermic reactions A chemical reaction that releases more thermal energy than it absorbs.
inhibitor A substance that slows the rate of a reaction by reducing the effectiveness of catalysts.
law of conservation of energy The law that states that energy cannot be created or destroyed but only transferred between objects or transformed; also known as the first law of thermodynamics.
LeChatelier's principle The principle that states that a chemical system in equilibrium will adjust its equilibrium position in such a way as to reduce the effect of any changes made to the system.
molar mass The mass of one mole of a substance.
mole SI fundamental unit for the quantity of matter in a substance; a count equal to 6.022 x 10 to the 23rd power.
oxidation A loss of electrons in a chemical reaction.
product A substance that is formed during a chemical reaction.
reactant A substance that enters into a chemical reaction.
reaction rate The speed of reaction.
reduction A gain of electrons in a chemical reaction.
reversible reaction A reaction in which the products can react together to re-form the original reactants.
single-replacement reactions A chemical reaction in which one element in a compound is replaced by another element; also known as a single-displacement reaction.
synthesis reaction A chemical reaction in which two or more reactants combine into a single, more complex product.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
