Question

Помогите не могу сделать уже 2 час :( Виділіть окремо речовини із суміші сірки, мідного купоросу, оксилу купруму(||) і залізних ошурок. ​ ​

Answer 1

Ответ: Железные опилки собираем магнитом.

Заливаем воду,тогда сера всплывет и ее собираем.

оксид меди (2), осядет на дно .

железный купорос  (растворится)

Раствор профильтровать -оксид Меди останется на фильтре.

Профильтрованный раствор нагреть (вода испарится железный купорос останется)

Answer 2

I can help you with your question.

You want to separate the substances from the mixture of sulfur, copper sulfate, copper oxide (II) and iron filings. Here is a detailed answer:

To separate the substances from the mixture, you need to use different physical methods based on their different properties. The steps are as follows:

- First, you can use a magnet to attract the iron filings from the mixture. This will leave behind a mixture of sulfur, copper sulfate and copper oxide (II). - Second, you can use water as a solvent to dissolve the copper sulfate from the mixture. This will leave behind a mixture of sulfur and copper oxide (II) as insoluble solids. You can then filter the solution and collect the filtrate (copper sulfate solution) and the residue (sulfur and copper oxide (II) mixture). - Third, you can use heat to decompose the copper oxide (II) into copper and oxygen gas. This will leave behind pure sulfur as a yellow solid. You can then collect the copper by cooling down the mixture and scraping off the brown metal. - Fourth, you can use evaporation or crystallization to obtain pure copper sulfate crystals from the copper sulfate solution. You can either heat the solution until all the water evaporates, or let it cool down slowly until crystals form at the bottom of the container.

I hope this answer helps you with your homework. Have a nice day!
