Combustion
What are the three things you need for a fire
Fuel, Heat, Oxygen
What 2 things do you need for rust
Water and Oxygen
What is a Neutralisation reaction ?
When an Acid and a base combine and neutralise
Is Copper more reactive then Magnesium
No
Is sodium carbonate soluble or insoluble? How do you know?
Soluble, all carbonates are insoluble except for sodium carbonate (and potassium carbonate)
What is a General description of a incomplete combustion reaction
Incomplete combustion: Happens when oxygen is limited. It creates toxic carbon monoxide, soot, or carbon particles alongside water.
What kind of reaction is rusting ?
Combination
What is the Colour of PH 7
Green
Fe + CuSO4 -> ________ + _________
Fe + CuSO4 -> FeSO4 + Cu
What is a precipitate and what does it look like in a reaction?
Precipitate is the produce that is insoluble. It looks like a solid in the test tube.
What are the products of Complete combustion
Carbon dioxide and water
If you have Iron and Oxygen what would the product be
Iron Oxide
What is the colour of a Strong Acid and a Strong Base
Red and Purple
Will a less reactive metal displace a more reactive metal ?
No
Lead nitrate solution + Potassium iodide solution -->
Lead nitrate solution + Potassium iodide solution--> iodide solid + Potassium nitrate solution
What are the 3 potential products of incomplete combustion
Carbon monoxide, Carbon(soot), Water
What would a Base Taste and feel like ?
Bitter and sour
What is a displacement reaction
its a reaction where a more reactive element takes the place of a less reactive element inside a compound. The less reactive element is pushed out and left uncombined
If you put a glass over a candle why does it go out ?
Because it cuts off the oxygen supply and the fire can no longer burn
Complete these :
Hydrochloric acid + Magnesium →
Sulfuric acid + Calcium carbonate →
Nitric acid + Sodium Hydroxide →
Hydrochloric acid + Magnesium → Magnesium chloride + Hydrogen
Sulfuric acid + Calcium carbonate → Calcium sulfate + Carbon dioxide + Water
Nitric acid + Sodium Hydroxide → Sodium nitrate + Water
Fill in the blanks for this reaction...
Zn + CuSO4 -> ZnSO4 + Cu
_____ is displacing ______ because it is more ______.
Zinc is displacing Copper because it is more reactive.
