MANUFACTURED SUBSTANCES IN INDUSTRY
SULPHURIC ACID
MADE IN INDUSTRY THROUGH THE CONTACT PROCESS
THE BURNING OF FOSSIL FUELS SUCH AS PETROL AND PRODUCTS FROM SULPHURIC ACID WILL SULPHUR DIOXIDE THAT POLLUTES THE ENVIRUNMENT
USED TO MAKE FERTILISER, THE ELECTROLYTE IN CAR BATTERIES, PAINT AND DETERGENT
AMMONIA
MASS PRODUCES IN FACTORIES THROUGH THE HABER PROCESS
EXAMPLES OF AMMONIA THAT CAN BE USED FOR FERTILISERS ARE ARE AMMONIUM SULPHATE , AMMONIUM NITRATE, AND AMMONIUM PHOSPHATE
AN ALLOY IS A COMPOUND FORMED BY MIXING METALS WITH OTHER ELEMENTS
THE PROCESS OF MIXING TOMS OF PURE METALS AND ATOMS OF IMPURITIES SUCH AS METALS OR NON-METALS BY MELTING IS CALLED ALLOYING
ALLOYING AIMS TO
IMPROVE THE APPEARANCE OF METALS SO THAT THEY ARE MORE ATTRACTIVE
PREVENT METAL CORROSION
INCREASES THE STRENGTH AND HARDNESS OF METAL
POLYMER
A LONG-CHAINED MOLECULE MADE FROM THE COMBINATION OF MANY SMALL MOLECULES (MONUMERS)
POLYMERISATION IS THE PROCESS OF COMBINING MONUMERS O FORM A LONG-CHAINED POLYMER
A NATURAL POLYMER IS A POLYMER THAT OCCURS NATURALLY, SUCH AS STARCH AND CELLULOSE
A SYNTHETIC POLYMER IS MAN-MADE POLYMER THAT IS FORMER FROM CHEMICAL COMPOUNDS THROUGH POLYMERISATION
GLASS
MAIN COMPONENT OF GLASSES ARE SILICA OR SILLICON DIOXIDE
TYPES OF GLASSES INCLUDES SILICA GLASS,SODA LIME GLASS, BOROSILLICATE GLASS AND LEAD CRYSTAL GLASS
BRITTLE, HARD AND TRANSPARENT AND CHEMICALLY INERT
CERAMICS
BRITTLE,HARD, A GOOD INSULATOR OF HEAT AND ELECTRICITY, HIGH MELTING POINT
