Answer 1

1)2Al+3Cl2>>2AlCl3.реакция соединения

2)CaO+2HCl>>CaCl2+H2O:реакция обмена

3)CuSO4+Zn>>ZnSO4+Cu; реакция замещения

4)3H2O+P2O5>>2H3PO4;  реакция соединения

5)Cu (OH)2+2HCl>>CuCl2+2H2O.  реакция обмена

Answer 2

Reaction 1: Al + Cl2 -> AlCl3

The reaction between aluminum (Al) and chlorine gas (Cl2) produces aluminum chloride (AlCl3). This is a combination reaction or a synthesis reaction.

Reaction 2: CaO + HCl -> CaCl2 + H2O

The reaction between calcium oxide (CaO) and hydrochloric acid (HCl) produces calcium chloride (CaCl2) and water (H2O). This is a neutralization reaction.

Reaction 3: CuSO4 + Zn -> ZnSO4 + Cu

The reaction between copper sulfate (CuSO4) and zinc (Zn) produces zinc sulfate (ZnSO4) and copper (Cu). This is a single replacement reaction or a displacement reaction.

Reaction 4: H2O + P2O5 -> H3PO4

The reaction between water (H2O) and phosphorus pentoxide (P2O5) produces phosphoric acid (H3PO4). This is a hydration reaction.

Reaction 5: Cu(OH)2 + HCl -> CuCl2 + H2O

The reaction between copper hydroxide (Cu(OH)2) and hydrochloric acid (HCl) produces copper chloride (CuCl2) and water (H2O). This is a neutralization reaction.
