9E Reactions of metals and their compounds

Elements What is an element? Where can we find a list of all the elements? Where are the metals in the periodic table? Give 3 examples. Where are the non-metals? Give 3 examples.

Colour this periodic table and put a key to show metals, non-metals and metalloids

Group I Metals What are the Group I Metals called? Name the group I Metals and write their symbols Which is the most reactive metal? Which is the least reactive? What happens to reactivity as you go down the group?

Metals and water Name 3 metals that react with water. Name a metal which reacts violently with water. Complete this general equation: Metal + water → __________ _______ + ________

Symbol equations How do the names of these elements change in a compound? Oxygen: Chlorine: Bromine: Iodine: Why do we have to balance symbol equations?

Group II Metals What are the group II Metals called? Name the group II Metals and write their symbols. What happens to reactivity as you go down the group?

Group II Metals Aim: To investigate the reactivity of group II metals with water. Draw and write about what you see when each metal is placed in water

Metals and acids Name 3 metals Name 3 acids What happens when a metal reacts with an acid? Complete this equation Metal + Acid _______ +______ Hydrogen + salt

A reaction that usually makes hydrogen is the reaction of a metal and an acid. You are going to test several metals to see if they react with the acid. Remember you are looking for bubbles! Fill in the table in your booklet.

Aim: to compare how metals react with acid. Prediction: Reaction with acid Copper Iron Magnesium Zinc Pupils do experiments in test tubes with small volume of acid (SAFETY GLASSES) They add a piece of the metal and write down the observations They should put a bung/cork in the test tube to allow for Hydrogen test later

Now write word and symbol equations for the reactions…

Metals and oxygen What is produced when a metal reacts with oxygen? Name a metal that reacts violently with oxygen. Name a metal that reacts slowly with oxygen.

The reactivity series What is the reactivity series?

Acids and carbonates Name two carbonates Complete this equation Acid + carbonate ______ + _______ + ________ Salt + carbon dioxide + water

A reaction that makes carbon dioxide is the reaction of a carbonate and an acid. These things are all carbonates.

Carbonate Reaction with acid Copy and complete this table to describe the reactions of carbonates with acid Carbonate Reaction with acid Marble (Calcium carbonate) Chalk (calcium carbonate) Indigestion tablet (Sodium bicarbonate) Bicarbonate of soda (Sodium bicarbonate) Pupils do experiments in test tubes with small volume of acid (SAFETY GLASSES) They add a small piece of the carbonate and write down the observations At the end do a teacher demo with gas collection apparatus and demo Carbon dioxide test.

Now write a conclusion with word and symbol equations for the reactions…

Displacement reactions What is a displacement reaction? How do we know if one metal will displace the other?

Aim: To investigate displacement reactions of metals and salts Zinc ___________ Magnesium ________ Copper ____________ Lead __________ http://www.nuffieldfoundation.org/print/3034

Conclusion Which dimples had a chemical reaction? Write word equations for these reactions. Write symbol equations. The symbols of the salts are as followed Copper sulphate: CuSO4  Lead nitrate: Pb(NO3)2 Magnesium sulphate: MgSO4 Zinc sulphate solution: ZnSO4

What is a displacement reaction? A more reactive metal can take the place of a less reactive metal in a compound. Magnesium+ copper sulphate Magnesium + Copper sulphate

Displacement reactions sheet

What can they be used for?

Uses: Thermite weilding

Ore extraction

The thermit reaction What type of reaction is the thermit reaction? Where is it used? Write the symbol equation of the Thermit reaction?

The thermite reaction Aluminium + iron oxide Aluminium + iron oxide

Gas tests recap What is the test for Oxygen? What is the test for Carbon dioxide? What is the test for Hydrogen? http://youtu.be/LiAvDpl5aJA
