Dear Jane

Объяснение:

I am happy to receive a letter from you. My parents also work a lot, and they are exhausted in the evening so much homework is done by me. I clean the house with a vacuum cleaner every second day. I wash the dishes and do the shopping. My parents trust me to buy bread, milk and other goods according to my mom's shopping list. I do not cook. I just prepare all the necessary ingredients so my mom can make dinner fast for us.

I love my family, and all the activities we do together are the happiest moments of my life. But most of all, I love sitting in the living room and talking to my parents about the daily staff.

I am looking for more letters from you,

NAME

1. Text 5 goes under the title "Phosphorus" and describes this element in the Periodic Table in great details.
2. The author gives many interesting facts concerning the properties and peculiarities of phosphorus and compares it with (w/) nitrogen.
3. Firsly, phosphorus and nitrogen have much in common, but they also differ greatly.
4. While nitrogen is quiete inactive under ordinary conditions, phosphorus reacts rapidly both w/ metals and non-metals.
5. At ordinary temperature, nitrogen is a gas, and phosphorus is a solid.
6. Secondly, phosphorus has the following properties:
- it is almost insoluble in water;
- it dissolves in many solvents.
7. The article goes on that phosphorus exists in several aliotropic forms, only 2 of them are of general interest. One is white phosphorus.
8. The most striking property of white phosphorus is its activity w/ oxygen.
9. It is very combustible, that's why it must be left under water.
10. The author gives some measures of precaution while handling white phosphorus.
11. They are as follows:
- never handle white phosphorus w/ bare hands;
- always remember that it's very poisonous, it may cause chronic poisoning.
12. In the conclusion, it should be mentioned that red phosphorus is a more stable form. It isn't so combustible, but the products formed are the same produced by white phosphorus.
That's about all;-)
