Answer 1

1).Cu(OH)2+2HNO3=Cu(NO3)2+2H2O (реакция обмена)
2).3Mg+2H3PO4=Mg3(PO4)2+3H2 (реакция замещения)
3).H2+Cl2=2HCl ( реакция соединения)
4). 2Fe(OH)3=Fe2O3+3H2O ( реакция разложения)

Answer 2

Chemical Equations and Reaction Types

Let's balance the given chemical equations and identify the reaction types:

1. Cu(OH)2 + HNO3 This is a neutralization reaction, resulting in the formation of a salt and water.

The balanced equation is: ``` Cu(OH)2 + 2HNO3 → Cu(NO3)2 + 2H2O ``` [[2 #]]

2. Mg + H3PO4 This is a single displacement reaction, where magnesium displaces hydrogen from phosphoric acid.

The balanced equation is: ``` 3Mg + 2H3PO4 → 3Mg(H2PO4)2 + 3H2 ``` [[3 #]]

3. H2 + Cl2 This is a synthesis reaction, resulting in the formation of a single compound.

The balanced equation is: ``` H2 + Cl2 → 2HCl ``` [[1 #]]

4. Fe(OH)3 This seems to be an incomplete equation. If you have a specific reaction in mind involving Fe(OH)3, please provide the reactants for a complete balanced equation.

I hope this helps! If you have any more questions or need further assistance, feel free to ask.
