Hi
I'm having trouble with a few questions about classifying the following reaction types.
1. Reaction: BaCl
2(aq) + Na
2(aq)
BaSO
4(s) + NaCl(aq)
My answer: It's a Precipitation reaction as well as a redox reaction.
2. Reaction: Zn(s) + 2HCl(aq)
ZnCl
2(aq) + H
2(g)
My answer: Single Replacement reaction and Redox reaction
3. Reaction: Na
2CO
3(aq) + 2HCl(aq)
2NaCl(aq) + H
2O(l) + CO
2(g)
My Answer: Double Displacement Reaction and Decomposition Reaction
Reaction 4: CuSO
4(aq) + 2NaOH(aq)
Na
2SO
4(aq) + Cu(OH)
2(s)
My Answer: Double Displacement reaction and Precipitation Reaction
Reaction 5: Cu(OH)
2(s) + H
2SO
4 2H
2O(l) + CuSO
4(aq)
My Answer: Acid-Base neutralisation reaction and double displacement reaction
Reaction 6: Zn(s) + CuSO
4(aq) :rarrow:ZnSO
4(aq) + Cu(s)
My Answer: Precipitation Reaction, Single replacement reaction and redox reaction
I'm very unsure whether I am right or wrong, can someone please verify.
