Synthesis

Front

The combination of 2 or more simple substances to form a more complex substance Element +element = compound Ex: A + B - - > C

Back

Single Replacement

Front

Replacement of a metal in a compound by a more active metal Ex: AB + C --> AC + B

Back

atomic number

Front

number of protons in an atom

Back

liquid

Front

If you add enough heat to a solid, it will usually change into a _____. ? (gas, liquid, solid)

Back

Diatomic molecules

Front

when covalent bonds are formed between two of the same element.

Back

Single bond

Front

when a pair of electrons are shared.

Back

Neutron

Front

Neutrally charged particle

Back

Proton

Front

positively charged particle

Back

Solid

Front

A form of matter that has its own shape and volume.

Back

REACTANTS:

Front

Starting substances.

Back

atom

Front

the smallest sample of an element that still retains the chemical properties of that element

Back

Anions

Front

Negative atoms

Back

Decomposition

Front

Two or more simpler substances form when a complex compound breaks apart. Ex: AB - -> A + B

Back

solid

Front

If you remove enough heat from a liquid, it will normally change into a _____.

Back

Electron

Front

Negatively charged particle, weightless

Back

Octet rule

Front

States that atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell.

Back

Ionic bonds

Front

Strong bond, atoms lose or gain electrons to form bonds.

Back

Exothermic

Front

Energy is released during the reaction

Back

Nitrate

Front

(NO3)-1

Back

Gas:

Front

A form of matter that flows to fill the shape of its container, but also fills the volume of its container.

Back

Extensive Properties:

Front

Amount of a substance left; this can include mass, volume, and length.

Back

Product:

Front

New substance formed.

Back

gas

Front

If you add enough heat to a liquid, it will normally change into a _____.

Back

Nitrite

Front

(NO2)1-

Back

Double Replacement

Front

Compound + Compound --> Compound + Compound EX: AB + CD --> AD + CB

Back

Conservation of Mass:

Front

Mass can not be created nor destroyed during a chemical reaction, it is conserved.

Back

Liquid:

Front

A form of matter that flows, has constant volume, and takes the shape of its container.

Back

Endothermic

Front

Energy is absorbed during the reaction

Back

Double bond

Front

when two pairs of electrons are shared.

Back

sublimation

Front

The "special" phase change that happens when a solid changes directly into a gas (skipping the liquid phase) is called _____.

Back

Triple bond

Front

when three pairs of electrons are shared.

Back

Cations

Front

Positive atoms

Back

Intensive Properties:

Front

Properties that are not dependent on the amount of the substance.

Back

Covalent bonds

Front

Strongest bond, atoms share valence electrons to become stable.

Back

mass number

Front

total number of protons and neutrons in an atom

Back

liquid

Front

If you remove enough heat from a gas, it will usually change into a _____.

Back
