Відповідь:

Для того, щоб знайти масову частку оксигену в СО, потрібно обчислити масу кисню в 1 молі СО. Оскільки у молекулі СО 1 атом кисню, то маса кисню дорівнює 16 г/моль.

Тепер можна обчислити масову частку оксигену в СО за формулою:

масова частка О = (маса О / маса СО) x 100%

масова частка О = (16 г/моль / 28 г/моль) x 100% ≈ 57,1%

Отже, масова частка оксигену в СО становить близько 57,1%.

помогите срочно напиште в Inderect speech Alice Freeman is a lawyer from San Francisco. Is food a pleasure for you? Not really. I enjoy certain kinds of food but most meals are just fuel to keep me going through the day. What do you normally eat in a typical day? I usually have a bowl of cereal or toast for breakfast. For lunch I eat at a restaurant near my office. I prefer Japanese or Indian food. I usually eat rice with fish and vegetables, soup or sushi. I don’t eat meat, but I eat a lot or fish. In the evening, I just have something light at home. Do you ever cook? Not very often. I don’t have the time or talent to cook full meals. I usually heat up a frozen meal or order a takeaway. Do you ever eat unhealthy food? Sometimes I get fast food for lunch. I have to admit that I love French fries. I feel terrible about it afterwards, but I don’t do it very often. Are you trying to cut down on anything at the moment? I am trying to cut down on the amount of fat I eat. I’m also trying to eat more wholemeal bread. Are people’s diet in your country getting better or worse? I think people are trying to improve their diets, but they are doing it the wrong way by following diets like the Atkins diet. Personally, I don’t thinks it’s very healthy to cut out entire groups of foods like carbohydrates.
