(6 cards)
1
Q
What is a displacement reaction?
A
More reactive metal replaces a less reactive one in a compound
2
Q
Metal + Acid = ?
A
Salt + Hydrogen
3
Q
Metal Carbonate + Acid = ?
A
Salt + CO₂ + H₂O
4
Q
Why are Group 1 metals more reactive down the group?
A
Larger atoms, weaker attraction to outer electron, easier to lose it
5
Q
Why is hydrogen in the reactivity series?
A
To compare metals with hydrogen when reacting with acids
6
Q
How is iron extracted from Fe₂O₃?
A
Using carbon to displace it: Fe₂O₃ + 3C → 2Fe + 3CO
