Flashcards in Chapter 2 Deck (17):
1

Chemical Reaction

The process by which one or more substances change to produce one or more different substances

2

Precipitate

A solid that is produced as a result of a chemical reaction solution

3

Chemical Formula

A combination of chemical symbols and numbers to represent a substance

4

Chemical Equation

A representation of a chemical reaction that uses symbols to show the relationship between the reactant and the products

5

Reactant

A substance or molecule that participates in a chemical reaction

6

Product

The substance that forms in a chemical reaction

7

Law of Conservation of Mass

The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes

8

Synthesis Reaction

A reaction in which two or more substances combine to form a new compound

9

Decomposition Reaction

A reaction in which a single compound breaks down to form two or more simpler substances

10

Single-Displacement Reaction

A reaction in which one element or radical takes place of another element or radical in a compound

11

Double-Displacement Reaction

A reaction in which a gas, solid precipitate, or a molecular compound forms from the exchange of ions between two compounds

12

Exothermic Reaction

A chemical reaction in which heat is released to the surroundings

13

Endothermic Reaction

is a chemical reaction that releases energy by light or heat.

14

Law of Conservation of Energy

is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.

15

Activation Energy

the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.

16

Inhibitor

a substance that slows down or prevents a particular chemical reaction or other process, or that reduces the activity of a particular reactant, catalyst, or enzyme.

17

Catalyst

a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
