Question

Cu(NO3)2-Zn(NO3)2-Al(No3)2-MgNO3)2

Answer 1

3Zn(NO3)2 + 2Al = 2Al(NO3)3 + 3Zn

Answer 2

Cu(NO₃)₂+Zn=Zn(NO₃)₂+Cu↓

3Zn(NO₃)₂+2Al=2Al(NO₃)₃+3Zn↓

2Al(NO₃)₃+3Mg=3Mg(NO₃)₂+2Al↓

Answer 3

The chemical formula you provided, "Cu(NO3)2-Zn(NO3)2-Al(No3)2-MgNO3)2," appears to be incorrect. There is a closing parenthesis ")" missing after "Mg(NO3)2." Additionally, it seems like you intended to write separate formulas for each compound, rather than combining them with hyphens.

Here are the correct chemical formulas for the compounds you mentioned:

1. Copper(II) nitrate: Cu(NO3)2
2. Zinc nitrate: Zn(NO3)2
3. Aluminum nitrate: Al(NO3)3
4. Magnesium nitrate: Mg(NO3)2

Please note that aluminum nitrate has a subscript of "3" outside the parenthesis, indicating that there are three nitrate ions for every aluminum ion.
