Preguntas del test (15)
1The gas in the air that reacts with metals most easily is:
- AA argon.
- BB carbon dioxide.
- CC nitrogen.
- DD oxygen.
2 A metal that does not react with the air is:
- AA calcium.
- BB gold.
- CC iron.
- DD magnesium.
3The gas which is given off when metals react with water is:
- AA carbon dioxide.
- BB hydrogen.
- CC oxygen.
- DD nitrogen.
4Sodium reacts with water to form:
- AA sodium chloride.
. - BB sodium oxide.
- CC sodium hydroxide
- DD sodium carbonate.
- AA sodium chloride.
5The gas which is given off when metals react with acids is:
- AA carbon dioxide.
- BB hydrogen.
- CC oxygen.
- DD nitrogen.
6When magnesium reacts with sulfuric acid, it forms:
- AA magnesium oxide.
- BB magnesium chloride.
- CC magnesium sulfate.
- DD magnesium carbonate.
7Look at these diagrams, and then choose the correct order of reactivity for metals X, Y and Z (the most reactive metal should
be first).
- AA) Z, X, Y
- BB) Y, Z, X
- CC) X, Y, Z
- DD) Z, Y, X
8Choose the correct statement to complete this word equation:
zinc + sulphuric acid →- AA) zinc + sulfur + acid
- BB) zinc hydrate + sulfur
- CC) zinc sulfate + hydrogen
- DD) zinc hydroxide + hydrogen
9Iron is more reactive than copper. If a piece of iron is put into copper sulfate solution, what would you see?
- AA) Brown copper would appear on the iron.
- BB) Blue copper would appear on the iron.
- CC) Nothing would happen.
- DD) The iron would dissolve completely.
10 Zinc is more reactive than tin. It will displace tin from a compound.
Choose the correct statement to complete this word equation:
zinc + tin sulphate →- AA) zinc + tin sulfate
- BB) zinc + zinc sulfate
- CC) tin + zinc sulfate
- DD) tin + zinc chloride
11 Copper is more reactive than silver. Iron is more reactive than copper.
This means that:- AA copper will react with iron nitrate solution.
- BB silver will react with iron nitrate solution.
- CC iron will react with silver nitrate solution.
- DD silver will react with copper nitrate solution.
12 Zinc reacts with copper sulphate solution and silver nitrate solution.
This means that zinc ..........- AA) is more reactive than copper and silver.
- BB) is less reactive than copper and silver.
- CC) is less reactive than copper but more reactive than silver.
- DD) is less reactive than silver but more reactive than copper.
13Some window frames are made of aluminium.
It is a good metal to use because:- AA) it conducts electricity.
- BB) it conducts heat.
- CC) it does not melt easily.
- DD) it does not react very quickly with air or water.
14Magnesium would react more slowly with acid if you:
- AA) added more acid.
- BB) added more water.
- CC) heated the acid.
- DD) used a more concentrated acid.
15The test for hydrogen gas is that it:
- AA) pops a lighted splint.
- BB) relights a glowing splint.
- CC) turns cobalt chloride paper pink.
- DD) turns limewater milky.
