m(C2H5OH) = 200 *0.8 = 160 г. 2C2H5OH + O2 -> 2CO2 + 2H2O160г/88г = xл/44.8лx=160*44.8/88 = 80л

British Meals
Alexander already has some ideas about typical British food. The usual
meals are breakfast, lunch, tea and dinner. Breakfast is generally a bigger meal
than they have on the Continent, though some English people like a "continental"
breakfast of rolls and butter and coffee. But the usual English breakfast is
porridge or corn flakes with milk or cream and sugar, bacon and eggs,
marmalade (made from oranges) with buttered toast, and tea or coffee. For a
change you can have a boiled egg, cold ham or perhaps fish.
They generally have lunch at about one o'clock. The businessman in London
usually finds it impossible to come home for lunch, and so he goes to a cafe or
restaurant; but if they can make it home for lunch, they have cold meat (left over
probably from yesterday's dinner), potatoes, salad and pickles, with a pudding or
fruit to follow. Sometimes we have a mutton chop, or steak and chips, followed by
biscuits and cheese, and some people like a glass of light beer with lunch.
Afternoon tea you can hardly call a meal, but it is a sociable sort of thing, as
friends often come in then for a chat while they have their cup of tea, cake or
biscuits.
In some houses dinner is the biggest meal of the day. They begin with soup,
followed by fish, roast chicken, potatoes and vegetables, a sweet, fruit and nuts,
coffee. But in a great many English homes we make the midday meal the chief one
of the day, and in the evening we have simple dinner – an omelette, or sausages,
sometimes bacon and eggs and sometimes just bread and cheese, a cup of coffee or
cocoa and fruit.
