An element is something that is made up from one atom.
A molecule is things that dont contain any metal but are joined together.
If you put a number in front of the molecule, you multiply all the atoms by that number.
Word and symbol equations
(what you start with) (what you make)
Conservation of mass
Conservation of mass means no atoms are lost or made during a chemical reaction, so the mass is equal to the reactions. so the mass is equal to the reactions.
Decomposing carbonate= salt
metal + acid - metal + carbon + water
carbonate salt dioxide H20
Decomposing carbonate= chloride
metal + hydrocloric acid - metal + carbon + water
carbonate chrloide dioxide H20
Decomposing carbonate= sulphate
metal + sulphuric acid - metal + carbon + water
carbonate sulphate dioxide H20
Decomposing carbonate= nitric
metal + nitric acid - metal + carbon + water
carbonate nitric dioxide H20
Decomposing carbonate= phosphoric
metal + phosophoric acid - metal + carbon + water
carbonate phodpohote dioxide H20
A transition metal is a metal in between state. they come between group 2+3
used for poetry - colourful compound
high melting point, but zinc is low
acts a catalyst
how heavy something is for its weight
measured in g/cm3
a catalyst speeds up the rate of reaction
catalysts reduce time and money and melting point
3 types of transition metals
Iron - used for engernerring, malable
opper- used for electric and heat, malable
Zinc- used for gavansing steel, malable
an ore is a metal in the earth ussally combined with another element.
Gold and Silver dont react with anything
anything under carbon can we extracted by carbon
anything above carbon can be extracted with electroylis
when you loose oxygen
metal oxide (in ore) -reduction- metal
Bio leaching and phytoming
doesnt use as much electricty as electroysis
uses plants to absorb metals from the soil
The raw materials used in a blast furnace are coke, limestone and iron ore
the word exacation is...
carobon monoxide+iron oxide - iron + carbon dioxide
the immperity is called ****
metals above carbon are transfered by electroysis
electroysis is breaking down ionic substances
possitive rods goes to negative rodnegative rods goes to the possive rod
Ore of aliminium is bonite
compound made is alaminium oxide
Loss of electrons Gain of electrons
when fish sink to the bottom of the sink to the bottom of the sea and the fish get compreessed because of the pressure and high temperature of the earth... the layers form oil!
longer chains means a higher melting point
hydrogen + carbon
hydrocarbons are made up from 4 bonds
TO BALENCE THE EQUATIONS START WITH THE CARBON AND END WITH THE OXYGEN
First 10 names are...
