Ответ:154,76л

Объяснение:

C2H4 + 3O2 = 2CO2 + 2H2OНа 5л нужно в 3 раза больше кислорода, т. е. 15лС2Н2 + 2,5О2 = 2СО2 + Н2ОЗдесь нужно 7*2,5 = 17,5 л

=> 17,5 + 15 = 32,5л воздуха

потребуется 32,5*100\21 = 154,76л

ца Animals in the air,пожалуйста.

One day in 1777 Josefh Montgolfier was relaxing in front of the fire with his laundry drying nearby.after a wrhile he noticed that one of his shirts had started to float upwarda.the toung man was curious abot what was happening so he thew some small pieces of paper into the fireplace to see it the same thing happened to them.when he saw them .when he saw them coming out of the chimney he came the conclusion that smoke had the power to lift things up and carry them through the air.Joseph loved science and wanted to become an inventor so he started thying to think of a craft that would be able to capture smoke and lift people off the ground.Alond with his brother Jacques he began perfoming experiments on something that later became the first hot-air balloon.
The Montgofier brothers quickly realised that it was heat and not smoke that had the power to lift things.On 19th September 1783 they presented their first hot-air ballon which was made from paper and clot .they burned some staw underneath it and the heat helped the ballon to float.As this was its first trip the Montgolfier brothers were too nervous to go up in the ballon themselves.So instead they put a sheep a duck and a chicken in the basket that hung below the balloon for the two-mile journey.
The new invention was a great success and the animals landed safe and sound.A huge crowd including some members of the French Royal Family gathered to watch the ballon floathing high in the sky.Shottly afterwards the brothers asked the king for permission to send men up the ballon.the king agreed and the first flight consisting of human passengers took place in Paris on 21ST november 1783 with great success .the balloon reached heights of around 150 metres as it floated aver the Paris rooftops starting a long a long tradition of hot-air ballooning.

после смерти царя Федора Иоанновича в 1598 году, московский престол занял Борис Годунов-его шурин, по большому счету к династии Рюриковичей не имевший никакого отношения.
Подумайте и назовите как минимум двух, живших на тот момент, претендентов, с династической точки зрения имевших права стать наследниками Федора Иоанновича.
