Answer 1

1. 2НСL+Mg---MgCl2+H2
2.2HCl+Na2O---2NaCl+H2O
3.HCl+AgNO3---AgCl+HNO3
4.2HCl+Cu---CuCl2+H2
5.HCl+KNO3---KCl+HNO3

Answer 2

HCl, also known as hydrochloric acid, can react with various substances. Let's examine the reactions with the given substances:

1. P2O5 (diphosphorus pentoxide): - Molecular equation: HCl + P2O5 → 2HPO3 - Ionic equation: 2H+ + 2Cl- + P2O5 → 2HPO3

2. Mg (magnesium): - Molecular equation: HCl + Mg → MgCl2 + H2 - Ionic equation: 2H+ + 2Cl- + Mg → Mg2+ + 2Cl- + H2

3. Na2O (sodium oxide): - Molecular equation: 2HCl + Na2O → 2NaCl + H2O - Ionic equation: 2H+ + 2Cl- + Na2O → 2Na+ + 2Cl- + H2O

4. KNO3 (potassium nitrate): - Molecular equation: HCl + KNO3 → KCl + HNO3 - Ionic equation: H+ + Cl- + K+ + NO3- → K+ + Cl- + H+ + NO3-

5. AgNO3 (silver nitrate): - Molecular equation: HCl + AgNO3 → AgCl + HNO3 - Ionic equation: H+ + Cl- + Ag+ + NO3- → AgCl + H+ + NO3-

6. Cu (copper): - Molecular equation: HCl + Cu → CuCl2 + H2 - Ionic equation: 2H+ + 2Cl- + Cu → Cu2+ + 2Cl- + H2

Please note that the molecular equations represent the overall reaction, while the ionic equations show the dissociation of the compounds into their respective ions.
