Periodic table
What is another name for horizontal rows in the periodic table?
periodic table
A period. The elements are in order of atomic number increasing.
Atoms
What are copounds?
Atoms
Atoms joined to other atoms using chemical bonds.
Atoms
What is a covalent bond?
Atoms
A chemical bond that involves sharing a pair of electrons between atoms is a molecule.
Atoms
Describe a chemical bond.
Atoms

Fuels from crude oil
CnH2n+2
Fuels from crude oil
What does distillation do?
Fuels from crude oil
It separates pure liquids from a mixture of liquids. It only works when liquids have varied boiling points.
Fractional Distillation
How does fractional distillation work?
Fractional Distillation
The substances are heated to their boiling point were they condense and separate.
Fractional Distillation
What is refinery gas used for?
Fractional Distillation
Bottled gas
Fractional Distillation
What is naphtha used for?

Limestone
What is the equation for the thermal decomposion of calcium carbonate?
Limestone
CaCO3 heat ----> CaO+ CO2 = limestone
metal carbonates decompose in the same way e.g copper carbonate
CuCO3 heat -----> CuO + CO2
