Question

Помогите пожалуйста!!! 1.H3PO4+Na2O 2.H3PO4+K2O 3.HNO3+K2CO3 4.HNO3+LiOH 5.HNO3+Cu

Answer 1

1.3Na2O + 2H3PO4= 2 Na3PO4+ 3H2O
2.3K2O + 2H3PO4 = 2 K3PO4+ 3H2O
3.K2CO3+2HNO3 = 2KNO3 + H2O + CO2
4. LiOH +HNO3= LiNO3+H2O
5.Cu + 4HNO3= Cu(NO3)2+ 2NO2↑+ 2H2O

Answer 2

1. H3PO4 + Na2O: H3PO4 is phosphoric acid, and Na2O is sodium oxide. When they react, they form sodium phosphate (Na3PO4) and water (H2O).

2. H3PO4 + K2O: H3PO4 is phosphoric acid, and K2O is potassium oxide. When they react, they form potassium phosphate (K3PO4) and water (H2O).

3. HNO3 + K2CO3: HNO3 is nitric acid, and K2CO3 is potassium carbonate. When they react, they form potassium nitrate (KNO3), carbon dioxide (CO2), and water (H2O).

4. HNO3 + LiOH: HNO3 is nitric acid, and LiOH is lithium hydroxide. When they react, they form lithium nitrate (LiNO3) and water (H2O).

5. HNO3 + Cu: HNO3 is nitric acid, and Cu is copper. When they react, they form copper nitrate (Cu(NO3)2) and water (H2O).
