Using Limestone Flashcards
Limestone is mainly what?
Calcium carbonate.
Where does limestone come from?
Quarried out of the ground.
Formed from sea shells.
What is limestone good for making?
Blocks for building.
What buildings are usually made out of limestone?
Cathedrals made purely from limestone.
As its sturdy.
What is the equation for calcium carbonate?
CaCO3.
What happens when calcium carbonate is heated?
It thermally decomposes.
Makes calcium oxide and carbon dioxide.
What is thermal decomposition?
When one substance chemically changes into at least 2 new substances when heated.
Give the equation for
calcium carbonate——–> calcium oxide + carbon dioxide.
CaCO3 —->Ca0 + CO2.
Same 4 other substances which thermally decompose in the same way.
Sodium carbonates.
Magnesium.
Copper.
Zinc.
When heated what does magnesium carbonate make?
Magnesium oxide and carbon dioxide.
What can’t a bunsen burner do?
Reach high enough temperatures to thermally decompose some carbonates in Group 1 metals.
Calcium carbonate reaches with acid to produce what?
Calcium salt.
Carbon dioxide.
Water.
The type of salt produced depends on what?
The type of acid used.
If hydrocholric acid was used what type of salt would be produced?
Chloride.
Name other carbonates which react with acid.
Magnesium.
Copper.
Zinc.
Sodium.
