about metals:
gold, zinc, copper-- shiny, good conducter of electricity/heat, strong, hard, solid/liquid.
1 of 19
about non-metals:
sulphur, phosphurus, silicon--brittle, dull, poor conducter of electricity/heat, solid/liquid/gas.

Metal & acid word equation:
METAL+ACID=HYDROGEN+SALT
3 of 19
Do all metals act the same with the same acid?
No, this is because they have different reactivity levels.
4 of 19
What product is produced through the reaction of metal & acid?
a salt
5 of 19
How is the salt made?
Its made by replacing the hydrogen atoms in an acid with metal atom(s)
6 of 19
What happens to magnesium if it reacts with hydrochric acid?
it becomes magnesium CHLORIDE
7 of 19
What happens to iron if it reacts with sulphuric acid?
it becomes iron SULPHATE
8 of 19
What happens to zinc if it reacts with nitric acid?
it becomes zinc NITRATE
9 of 19
why is it impossible to make copper sulphate?
copper does not have a high reactivity level.
10 of 19
Order of metals:
lithium, calcium, magnesium, aluminium, zinc, iron, tin, lead, copper, silver, gold.
11 of 19
Why when matal & acids react does part oth the metal from the original compound join another compound?
Because the metal is more reactive then the compund it was already joined to.
12 of 19
what is a base?
A base is a compund that can neutralise an acid. Many bases are metal oxide.
13 of 19
word equation for bases:
acid+base--->salt+ water e.g. nitric acid+sodium oxide---> sodium nitrate+water
14 of 19
What makes it not bubble?
The hydrogen joins onto the oxygen meaning it creates water.
15 of 19
Alkalis:
are bases which are disolvable it forms water and salt==alkali+acid-->salt+water.
16 of 19
alkalis you need to know:
sodium hydroxide, potassium hydroxide, calcium hydroxide.
17 of 19
What happens when acid +metal carbonates react?
produces carbon dioxide
18 of 19
word equation for metal and carbonates:
metal carbonate+acid--> salt+water+carbon dioxide
