METALS AND METAL COMPOUNDS
  1. PROPERTIES OF METALS
    1. APPERANCE
      1. SHINY
        1. REFLECT LIGHT
        2. DULL
        3. MELTING POINT
          1. HIGH
            1. MOST METALS HAVE HIGH MELTING POINTS
            2. LOW
              1. MERCURY
                1. LIQUID AT ROOM TEPRETURE
            3. STRENGTH
              1. MALLUBLE
                1. ANOTHER WORD FOR BENDY
                2. STRONG USALLY
                  1. USED TO MAKE BRIDGES ETC.
                3. MAGNETIC
                  1. COST
                    1. CONDUCTIVITY
                      1. HEAT
                        1. ELECTRICITY
                          1. COPPER WIRE
                      2. MAKING SALTS
                        1. FORMULA
                          1. ACID + METAL -> SALT + HYDROGEN
                          2. BASES
                            1. ALL ALKALIS ARE BASES
                              1. NOT ALL BASES ARE ALKALIS
                              2. OXIDES, HYDROXIDES AND CARBONATES
                                1. THESE ARE ALL BASES
                                  1. EXAMPLES
                                    1. MGO = MAGNESIUM OXIDE
                                      1. CUCO3 = COPPER CARBONATE
                                        1. CAOH2 = CALCIUM HYDROXIDE
                                  2. THE PH SCALE
                                    1. ACID AND ALKAIIES
                                      1. ACIDS WERE ON THE LEFT
                                        1. RED WAS A STRONG ACID
                                        2. ALKALIES WERE ON THE RIGHT
                                          1. A STRONG ALKALI WAS A DARK PURPLE
                                        3. WE CAN USE UNVIVERSAL INDICATER TO TELL WHAT PH IT IS
                                          1. THIS CAN COME AS TWO DIFFERENT FORMS
                                            1. PAPER
                                              1. LIQUID
                                              2. ALTERNATLY WE CAN USE A PH MONITOR RIGGED UP TO A COMPUTER
                                            2. ACIDS AND ALKALIES
                                              1. MIXING TOGETHER CAUSES NUTERLISATION
                                                1. ACID + ALKALI -> A SALT + WATER
                                                  1. WHEN NUETERLISATION TAKES PLACE YOU END UP WITH SALTY WATER
                                                    1. IF YOU EVAPERATED THE WATER YOU WOULD BE LEFT WITH SAT
                                                  2. IF YOU MIX AN ACID AND ALKALI THEY CANCEL EACH OTHER OUT
                                                    1. IT WOULD BE A NEUTERAL SUBSTANCE WITH A PH OF 7
                                                    2. THE ACID AND ALKALI MUST BE OF THE SAME STRENGTH AND AMOUNT
