Відповідь: 4,48л

розв'язок:

C6H12O6 = 2C2H5OH + 2CO2

n(C6H12O6) = 18\180 = 0,1 моль

n(CO2)=2*n(C6H12O6)=0,2моль

V(CO2)=0,2*22,4=4,48л

2 Read the three texts about different tours. Match texts A-C with questions 1-5. Two
texts have two matching questions.
A MOROCCAN MEDINAS AND MOONLIGHT SKIES
This ten-day tour takes you on an unforgettable journey into history and nature without any stress.
We start in the bustling narrow streets of Marrakech, filled with people, noises, smells, sights and
sounds that you will never forget. You can shop for souvenirs or sit and relax in a rooftop café
while watching the madness below. After two days in the city, we set out for Merzouga, on the
edge of the scorching Sahara Desert where sand dunes stretch into the distance and you can camp
out under a star-filled sky. After watching the sun come up, it is on to Fes, the UNESCO listed
city where time stood still. With its traffic-free old city, home to over 150,000 people, Fes can be
a shock to the senses but our guides will make sure you never get lost. Fes is what Marrakech
looked like before the tourists arrived. After sightseeing on the fifth day, we take you on a special
tour of the spice market and restaurants where your guide will help you to order freshly cooked
meat and sticky, sugary desserts which are loved by everyone.
B WAY OUT WEST, HALFWAY TO AMERICA
The Azores are a group of islands between Portugal and America. They are isolated but not
deserted as the volcanic hills are covered in beautiful flowers most of the year because the winters
are warm and the rain falls steadily all year round. Our package offers return flights from Lisbon
as well as six free ferry rides on any routes on offer. Each island offers something different but all
offer that Azores magic. On all islands, you can find gentle walks to unspoilt beaches, volcanic
rock, crystal clear lakes and historic cities. You can take a helicopter ride and look into the crater
of a volcano, you can swim with dolphins or dive with sharks. Bird watchers can spot eagles and
other birds of prey and the Azores are famous for the best whale watching in Europe. Most of all,
the Azores are a place to relax. The nine largest islands have a combined population of only
250,000 so there is plenty of empty space and, so far, the islands have avoided being swamped by
mass tourism.
C LAND OF ICE AND FIRE
This seven-day tour takes you from frozen glaciers to erupting volcanoes. You can explore inside
caves carved out of lava and swim in lagoons heated by water bubbling up in hot springs. Each
day you will be taken by mini bus in groups of no more than fourteen people to an area of
outstanding natural beauty. You need to be in reasonably good health as there will be fairly tiring
uphill hikes every day to lead you from roads to empty spaces inaccessible to motor vehicles. Our
guides will ensure your safety at all times as well as telling you more about the geology and
history of this incredible, and at times unwelcoming, landscape. All equipment necessary is
provided by us but, please remember, Iceland is an empty place. There are more sheep than
people here and our tours will take you far away from any shops or restaurants so you will need to
bring a packed lunch and any snacks that you require to keep your strength up during the day.
Which offer
I allows people to explore on their own?
2 gives people the chance to taste local delicacies?
3 requires travellers to be fairly fit?
4 limits the number of people that can be taken on a tour?
5 involves the observation of wildlife?
