Reactivity Flashcards
1
Q
What is oxidation?
A
- gain of oxygen
- loss of electrons
2
Q
What is reduction?
A
- loss of oxygen
- gain of electrons
3
Q
What does the reactivity series tell us?
A
- most reactive metals lose electrons more easily
4
Q
Which metals react with water?
A
- potassium
- sodium
- lithium
- calcium
5
Q
Which metals react with dilute acid?
A
- potassium
- sodium
- lithium
- calcuium
- magnesium
- zinc
- iron
metals more reactive than hydrogen
6
Q
What can a more reactive metal do to a less reactive metal?
A
displace it from its compounds
7
Q
What happens when a metal is added to acid?
A
- metal displaces hydrogen from acid
- metal is more reactive than hydrogen
8
Q
What are gold and other unreactive metals found in the earth’s crust as?
A
- native metals
- pure form of metal
9
Q
What are ores?
A
- compounds of metals
- need to undergo reactoin to extract metal
10
Q
How are metals less reactive than carbon extracted?
A
- heated to displace with carbon
11
Q
How are metals more reactive than carbon extracted?
A
- eletrolysis
12
Q
What salt does hydrochloric acid produce?
A
a chloride
13
Q
What salt does nitric acid produce?
A
a nitrate
14
Q
What salt does sulfuric acid produce?
A
a sulfate
15
Q
How do you compare the reactivity of metals using water and/or dilute acid?
A
- greater rate of bubbling = more reactive metal
