Do now!Can you talk to your partner about what
we learned last lesson?
Last lesson
• Know how to write the general word equation for the reaction between a metal and an acid
• Know how to predict the name of the product formed when a metal and an acid react
Word equations
Zinc + sulphur zinc sulphide
reactants product(s)
Naming compounds
Metal and non-metal
The name of the metal goes first, the non-metal changes the ending to “ide”
Sodium + chlorine Sodium chloride
Copper + oxygen Copper Oxidereactants product(s)
reactants product(s)
Can you complete the following word equations?
• Iron + oxygen ?
• Sodium + iodine ?
• ? + fluorine lithium fluoride
• Hydrogen + oxygen ?
• Calcium + ? Calcium chloride
• Copper + sulphur ?
Metals and acids
Hydrochloric acid + magnesium magnesium chloride + hydrogen
Nitric acid + iron iron nitrate + hydrogen
Sulphuric acid + zinc zinc sulphate + hydrogen
In general, hydrochloric acid makes a chloride, nitric acid makes a nitrate, and sulphuric acid makes a sulphate.
“salts”
Can you complete the following word equations?
• Iron + hydrochloric acid ?
• Sodium + sulphuric acid ?
• ? + zinc zinc nitrate
• ? + ? Lithiun chloride + ?
• Calcium + ? Calcium chloride + ?
• Gold + sulphuric acid ?
Today’s lesson
• Know what happens when rocks and acids react
• Know how to test for carbon dioxide
• Know how to write a word equation for the reaction between an acid and a metal carbonate
Acids and carbonates
Carbonates
Copper carbonate CuCO3
Sodium carbonate Na2CO3
Calcium carbonate CaCO3
carbonate “group”

Similar experiment to last lesson, only using calcium
carbonate instead of a metal. Collect the gas and try the
hydrogen test. The try adding some limewater to the test tube
and (carefully) shaking it)
