1
Q
What is an alloy?
A
A mixture of a metal with one or a few other elements.
2
Q
How are metals arranged in the reactivity series?
A
From the most reactive to the least reactive.
3
Q
What characteristics do more reactive metals possess?
A
- Greater tendency to form positive ions than a less reactive metal
- Able to displace a less reactive metal from its salt solution
- Able to reduce the oxide of a less reactive metal
4
Q
How does reactivity of a metal affect its oxides’ ability to be reduced by carbon or hydrogen?
A
The more reactive a metal is, the more difficult it is to reduce its oxide to the metal by carbon or hydrogen.
5
Q
How does reactivity of a metal affect its carbonate’s ability to be decomposed by heat?
A
The more reactive a metal is, the more difficult it is to decompose its carbonate by heat.
6
Q
What is steel?
A
An alloy of iron with carbon and/or other metals.
7
Q
What are the conditions for rusting to ensue?
