1) СuCl2 + 2NaOH = 2NaCl + Cu(OH)2
2) Cu(OH)2 + K2SO4 = 2KOH + CuSO4
3) CuSO4 + 2Na = Na2SO4 + Cu
4) 2Cu + O2 = 2CuO

1) Fe + H2SO4 = FeSO4 + H2
2) FeSO4 + 2KOH = K2SO4 + Fe(OH)2
3) Fe(OH)2 + HCl = FeCl2 + H2O

1) 2Fe(NO3)3 = Fe2O3 + 6NO2 + O2
2) Fe2O3 + 6HCl = 2FeCl3 + 3H2O
3) FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
4) 2Fe(OH)3 = Fe2O3 + 3H2O
5) Fe2O3 + 2Al = Al2O3 + 2Fe

1. Cu Cl2+2NaOH ⇒ Cu(OH)2+2Na CI
Cu(OH)2+H2SO4⇒CuSO4+2H2O
CuSo4+2K⇒ K2SO4+Cu
2Cu+O2 ⇒  2CuO
2. Fe+H2SO4⇒  Fe SO4+H2↑
Fe SO4+NaOH⇒   Fe(OH)2+Na2SO4
Fe(OH)2+2HCI⇒Fe CI2+2H2O

1. I woke too early.

2.I have my clothes, my books. I have all my things.

3 My luggage was in Russia.

4 Next day I decided to go to see London.

5 A man came to him and pulled out a gun

6 The man took all the money he had on him.

текс A. And this was the beginning of my problems. I woke up too late. I got to the airport and I saw that I hadn’t taken my passport. I took a taxi home and then back to the airport. I was very upset. I got on the plane. When I came to France, people at the airport told me that my luggage was in China. I didn’t have my clothes. I didn’t have my books. I didn’t have anything.



B. That was too much for me. I decided to leave Paris and go back to England. I phoned my friends in London, asked them to send me some money and I bought a plane ticket for the next flight. Finally, I was back home. When I arrived the travel agent informed me that my luggage was in Paris.



С. When I came to the hotel, they didn’t have a room for me because I hadn’t arrived on time. I went to another hotel where I could spend the night. The night was really hot and the air conditioning was broken. I couldn’t open the window because there was a very busy street outside and the noise was awful.

D. Next day I decided to go to see Paris. When I left the hotel I went straight to see the Eiffel Tower. Before I got there a man came to me and pulled out a gun. He took all the money I had on me.

E. It all started in the morning two months ago. I always wanted to see Paris, the cafes, the Eiffel Tower and Champs Elysees. So I bought a plane ticket to Paris and waited for the day of departure.
