Name some examples of Acidic oxides |
Non metal oxides CO NO2 |
|
|
name some examples of basic oxides |
Na2O, CaO metal oxides |
|
|
Properties of acidic oxides |
Acts like acid AReact with water to form acids React with bases forn salts |
|
|
Properties if Basic oxide |
Acts like base React with water to form bases React acids form salts |
|
|
What are Amphoteric oxides |
Oxides act as both base and acid Eg- Beryllium. Aluminium. Zinc. Lead. Tin and WATER |
|
|
What are some patterns on periodic table |
Basic oxides are on the left Amphoteric in between Acidic oxides are in right. Noble gases no oxides |
|
|
Define Le Chatlier Principle |
If a system at equilibrium is disturbed then systen readjust itself to minmise changes. |
|
|
What factors effect equilibrium |
1. Temperature 2. Pressure 3. Concentration 4. Volume |
|
|
What does a catalyst do to tge system |
Does not affect position of equilibrium Speed up reaction rate |
|
|
Changing concentration in equilibrium |
Equikibrium shift to the the side with that has no increase in conc. |
|
|
Changes in pressure |
Increase in pressure - moves to side with less moles of gas Decrease pressure - moves to side with more moles of gas |
|
|
Changes in volume |
Increase volume shift reaction decrease pressure favours side with mire moles Decrease volume increased pressure favours side with less moles. |
|
|
Changes in temperature |
Increase temperature shift to absorb heat |
