METALS AND REDOX Flashcards
OXYDATION IS THE (…)
ADDITION OF OXYGEN
REDUCTION IS THE (…)
REDUCTION OF OXYGEN
EXAMPLE OF OXIDATION WITH MAGNESIUM:
MGNESIUM GAINS OXYGEN TO BECOME MAGNESIUM OXIDE
2Mg+O2– 2MgO
EXAMPLE OF REDUCTION WITH COPPER
COPPER OXIDE IS REDUCED TO COPPER USING CARBON
2CuO + C —- 2Cu + CO2
IN OXIDATION THE SUBTSANCE THAT OXIDES THE METAL AND IS REDUCED IS THE (…)
OXIDISING AGENT
IN REDUCTION THE SUBSTRANCE THAT REDUCES THE METAL AND IS OXIDISED IS CALLED (…)
REDUCING AGENT
METALS THAT ARE (…) DONT TEND TO FORM COMPOUNDS WITH OTHER ELEMENS
UNREACTIVE
WHAT ARE METAL ORES
METALS THAT DO REACT WITH OTHER ELEMENTS TO FORM COMPOUNDS, WHICH CAN BE FOUND NATURALLY IN THE EARTHS CRUST
IF A COMPOUND CONTAINS ENOUGHT OF THE METAL TO MAKE IT WORTWHILE EXISTING; THE COMPOUND IS CALLED (…)
METAL ORES
THERE ARE (…) AMOUNT OF METAL ORES
LIMITED AMOUNT
THE MORE REACTIVE A METAL IS THE (…) FROM A COMPOUND
THE HARDER IT IS TO EXTRACT IT
HOW DOES THE COMMON METALS THAT FORM AN ORE (IRON AND ALUMINIUM) CAN BE SEPARATED BY ITS OXIDE
REDUCTION
ONLY METALS THAT ARE (…) CAN BE EXTRACTED
LESS REACTIVE THAN CARBON
WHY CAN METALS THAT ARE LESS REACTIVE THAT CARBON ONLY CON EXTRACT
BY A REDUCTION REACTION WITH CARBON
HOW IS THE EXTRACTION DONE
BY HEATING THE ORE WITH CARBON MONOXIDE
