6Li + N2 = 2Li3N
н лития = 10,5/7 = 1,5 моль
н азота - в 6 раз меньше: 1,5/6 = 0,25 моль.
Объём азота = 0,25*22,4 = 5,6 л.

Как можно озаглавить текст СРОЧНО ПОМОГИТЕ
The members of this family (the six grown-ups and little Charlie Bucket) live together in a small wooden house on the edge (на окраине) of a big town.
The house wasn’t large enough for so many people, and life was extremely uncomfortable for them all. There were only two rooms in the place, and there was only one bed. They gave the bed to the four grandparents because they were old and tired. Grandpa Joe and Grandma Josephine were on the one side, and Grandpa George and Grandma Georgina were on the other side.
Mr. Bucket and Mrs. Bucket and Charlie Bucket slept in the other room, upon mattresses on the floor. In the summertime, this wasn’t too bad, but in the winter, freezing cold draughts (сквозняки) blew across the floor all night long, and it was terrible. They could not buy a better house or even one more bed. They were very poor for that.
Mr. Bucket was the only person in the family with a job. He worked in a toothpaste factory, where he screwed (прикручивал) the little caps (крышки) on the tops of the tubes of the toothpaste all day long. But a toothpaste cap screwer never gets very much money. Poor Mr. Bucket worked hard, but he didn’t make much money to buy the things that the large family needed.
There wasn’t even enough money to buy good food for all of them. The only meals they could have were bread and margarine for breakfast, potatoes and cabbage for lunch and cabbage soup for supper. Sundays were a bit better. They all looked forward to Sundays because then everyone got a second helping (добавка).
