Chemical Equations

Balancing and Identifying Chemical Reactions

QuestionAnswer
Synthesis Reaction Two or more simple substances combine to form a more complex compound.
Decomposition A single compound breaks down into two or more simpler substances.
Single Replacement An element replaces another element in a compound.
Double Replacement The positive and negative ions of two ionic compounds are exchanged, forming two new compounds.
Combustion A substance reacts rapidly with oxygen, often producing heat and light.
Example of a synthesis reaction A + B = AB
Example of a decomposition reaction AB = A + B
Example of a single replacement reaction A + BC = AC + B
Example of a double replacement reaction AB + CD = AD + CB
Coefficients The number of a particular molecule in a chemical reaction.
Subscripts The number of a particular atom in a chemical reaction.
Reactants The substances are originally present in a chemical reaction, that are consumed during the reaction.
Products The chemicals created in a chemical reaction.
Conservation of mass Mass is not created or destroyed in a chemical reaction (it only changes).
Balancing equations Coefficients and subscripts always up up to the same number on both sides of the equation (reactants and products).
Chemical reaction A process that involves rearrangement of the molecular or ionic structure of a substance.

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.
