Naming Products Metal + Acid M+A Salt + Hydrogen S+H Magnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen 2. 26 Predict the products of reactions between dil. Hydrochloric, Nitric and Sulfuric Acids; and metals, metal oxides and metal carbonates. (Except Nitric Acid and Metals)

Naming Other Salts The salts formed are : Metal Salts The 1 st Part Of The Name Is From The Metal The 2 nd Part Of The Name Is From The Acid Lithium chlo ric Acid = Chloride Salts Hydrochlo Sodium Sulf uric Acid = Sulfate Salts Magnesium + Hydrochlo ric Acid Magnesium Chloride Task 4 Now try the examples on your worksheet 2. 26 Predict the products of reactions between dil. Hydrochloric, Nitric and Sulfuric Acids; and metals, metal oxides and metal carbonates. (Except Nitric Acid and Metals)

Check Your Knowledge Task 4 2. 26 (Plenary) Predict the products of reactions between dil. Hydrochloric, Nitric and Sulfuric Acids; and metals, metal oxides and metal carbonates. (Except Nitric Acid and Metals)

Combustion of hydrogen �Word equation �Hydrogen + oxygen water �Chemical equation �H 2 + O 2 H 2 O �Where do you think this reaction is used?

Chemical test for water �Anhydrous Cu. SO 4 +H 2 O Cu. SO 4. 5 H 2 O � colourless blue

Physical test for water �Melting point �Boling point �Freezing point �density
