Ответ:

У молекулі P2O5 масові частки елементів можна обчислити, використовуючи атомні маси елементів. Фосфор (P) має атомну масу близько 30.97 г/моль, а кисень (O) має атомну масу близько 16.00 г/моль.

Отже, масова частка фосфору (P) = (2 атоми P * атомна маса P) / молекулярна маса P2O5

Масова частка кисню (O) = (5 атомів O * атомна маса O) / молекулярна маса P2O5

Me and my phone

A surprise in the forest

I’m Linda, and my home is in the centre of a large city. The city centre is busy and noisy, and the traffic is terrible. So when our family goes on holiday, we usually travel somewhere relaxing. Last summer, we stayed in a hotel in the countryside. I went cycling with my brother a few times. We explored the forest near the hotel, too.

One morning, we were walking in the forest when we heard a noise. Something was climbing up a tree. It was a bear! “Is it dangerous?” I asked my brother. ”I’m not sure,” he answered. Soon the bear stopped climbing. I quickly took my mobile phone out of my bag. While the bear was sitting comfortably in the tree, I took a photo. Then we ran back to the hotel!

It was an interesting but scary experience. After that, we didn’t go back to the forest!

William Shakespeare

A Shakespeare was born in Stratford-Upon-Avon, a small town in England, in 1564. He went to school there, but he didn’t go to university - his family wasn’t rich, and university was expensive in those days.

B Shakespeare got married when he was only eighteen. About ten years later, he left Stratford and travelled to London: he wanted to be an actor, and all the important theatres were in London.

C Shakespeare’s wife and children stayed in Stratford, but he sometimes visited them. Stratford was 150 kilometres from London, and the journey took two days. There weren’t any cars or trains in those days; people rode on horses or walked.

D Shakespeare soon became interested in writing. When he was thirty, he wrote Romeo and Juliet. Everybody loved it! Many of his plays were very popular. He made a lot of money, and when he was about thirty-five he bought a big house in Stratford for his family.

E When he was about fifty, Shakespeare came back to Stratford to live with his family. He died a few years later.
