1. Нитрат калия = нитрит калия + кислород
2. Сульфат алюминия + хлорид бария = сульфат бария + хлорид алюминия
3. Железо + кислород = оксид железа(3)
4. Алюминий + серная кислота = сульфат алюминия + водород
5. Йодид алюминия + бром = бромид алюминия + йод
6. Ортофосфат кальция = оксид кальция + оксид фосфора(5)
7. Нитрат кальция + карбонат калия = карбонат кальция + нитрат калия
8. Оксид азота(5) + оксид калия = нитрат калия
9. Алюминий + йод = йодид алюминия
10. Гидроксид кальция + ортофосфорная кислота = ортофосфат кальция + вода

1) 2 KNO₃ ==(t°C)==> 2 KNO₂ + O₂↑ (реакция разложения)

2) Al₂(SO₄)₃ + 3 BaCl₂ ===> 3 BaSO₄↓ + 2 AlCl₃ (реакция обмена)

3) 4 Fe + 3 O₂ ===> 2 Fe₂O₃ (реакция присоединения)

4) 2 Al + 3 H₂SO₄ ===> Al₂(SO₄)₃ + 3 H₂↑ (реакция замещения)

5) 2 AlI₃ + 3 Br₂ ===> 2 AlBr₃ + 3 I₂ (реакция замещения)

6) Ca₃(PO₄)₂ ==(t°C)==> 3 CaO + P₂O₅ (реакция разложения)

7) Ca(NO₃)₂ + K₂CO₃ ===> CaCO₃↓ + 2 KNO₃ (реакция обмена)

8) N₂O₅ + K₂O ===> 2 KNO₃ (реакция присоединения)

9) 2 Al + 3 I₂ ===> 2 AlI₃ (реакция присоединения)

10) 3 Ca(OH)₂ + 2 H₃PO₄ ===> Ca₃(PO₄)₂↓ + 6 H₂O (реакция обмена)

It you want to see unusual animals, birds and plants, Australia is a good place to go.
The kangaroo is one Australian animal that everybody knows. The biggest of the fifty kinds is the red kangaroo. They can jump more than four metres and travel at seventy kilometres an hour. Kangaroos eat grass and leaves and live in small groups.
Everybody loves the sleepy grey koalas. Like kangaroos, they have a pouch, baby koalas ride on their mother's back. Koalas eat one kilo of leaves each day but drink nearly nothing. The word "koala" means "no water". Not everybody knows that the koala only looks like a bear but in fact is a different animal.
Two Australian animals, the echidna and the duckbill are really very unusual. Their babies come from eggs but drink milk from their mothers. No other animals in the world do this. The echidna eats ants. which it catches with its long fast tongue. The duckbill swims well, but it can only stay under water for some minutes.
There are more than eight hundred kinds of birds in Australia. The continent is the home of budgies and some kinds of parrots. The emu, which is two metres tall, is the second largest bird in the world. It cannot fly, but it can run at fifty kilometres an hour. Then there is the kookaburra bird. Its cry sounds like somebody's laughter. Australians like the bird. they even made up a song about it.
Kookaburra sits on old gum tree.
Merry, merry, king of the bush is he.
Laugh. Kookaburra. laugh. Kookaburra,
Happy your life must be.
Eucalyptus trees, or gum trees, grow in many places in Australia. These strong trees grow very fast and do not die when there are forest fires.
Australia is full of surprises and a lot of people dream to visit this continent and see it with their own eyes. ПЕРЕВОД ПОЖАЛУЙСТА!
