Lavoisier – Scientist who suggested acids contain oxygen
Nuclear fission – Insert picture
pH scale – a way to measure how acidic or basic a solution is
PH SCALE – Measures the acidity or alkalinity of an aqueous substance.
boiling point – The temperature at which a liquid changes to gas.
Hydrogen Carbonate (Bicarbonate) –
Intermolecular forces – Intermolecular forces are much weaker than Intramolecular forces. Intermolecular forces play a role in various properties and phases in particularly in liquids three major types of intermolecular forces are:
Dispersion forces
Dipole to dipole forces
Hydrogen bonding
EVAPORATING DISH – used to evaporate off liquids and leave behind solids
The simplest alkane is
Atom – The smallest particle of an element.
molecules – Chemicals that result from atoms linking together
Crude Oil – A mixture of hydrocarbons formed from the remains of dead sea life which was covered with silt on the sea bed and compressed over millions of years
The simplest аlkаne is
What effect do acids and bases have on universal indicator paper? – Acids: paper is anything between red and yellow. (depending on pH level)
Neutral: a green colour.
Bases: paper is anything between blue and purple. (depending on pH level)
