Physical Change
A change in a substance that does not involve a change in the identity of the substance - solid to liquid to gas
two reactions of endothermic reactions
Combustion process, rusting of iron, and freezing of water
household things with Ionic bonds
table salt, baking soda, washing soap,Epsom
Boiling point definition
The temperature at which a liquid boils and turns to vapor.
Name three or the most relevant chemical properties
flammability, toxicity, acidity
Chemical Properties
A change in matter that produces one or more new substances
examples of an exothermic reaction
When water freezes into ice cubes, the energy is released in the form of heat, Hot Packs
Three ionic bond properties
They form crystals, They have high melting points and high boiling points, They have higher enthalpies of fusion and vaporization than molecular compounds.
Freezing point definition
Definition of flammability
`Ability to support combustion especially
Endothermic Reactions
A reaction that ABSORBS energy in the form of heat - temperature increases
Exothermic definition
noting or pertaining to a chemical change that is accompanied by a liberation of heat (opposed to endothermic).
Ionic bonds definition
the electrostatic bond between two ions formed through the transfer of one or more electrons.
Melting point definition
The temperature at which a given solid will melt.
Definition of boiling point
The temperature at which a liquid boils and turns to vapor.
Exothermic Reaction
A reaction that RELEASES energy in the form of heat - temperature decreases
Endothermic definition
Chemistry. noting or pertaining to a chemical change that is accompanied by an absorption of heat (opposed to exothermic).
Covalent bonds definition
the bond is formed by the sharing of a pair of electrons by two atoms.
3 Freezing point depression examples
Science of Ice-Cream, Salting Icy Roads, Radiator fluids in Automobiles
Definition of Color
The property possessed by an object of producing different sensations on the eye as a result of the way the object reflects or emits light.
Methanol
