In separating mixtures is it an advantage or a disadvantage?
Serjik [45]

Answer:

Purpose: To become familiar with the techniques for separation of amixture of solids.

Explanation:

a mixture of pure substances. If you have a mixture of tennis ballsand marbles (not pure substances by the way), it would be easy toseparate the mixture. However, it is more difficult to separate asand (also not a pure substance) and salt mixture. Even with verygood tweezers and a magnifying glass, it would be extremelytedious. You could take advantage of the fact that salt dissolvesin water and sand does not. To separate iron powder from an ironand sand mixture you can take advantage of the magnetic propertiesof iron and separate the mixture.

To summarize a complete procedure for separating a mixture ofseveral substances, it is best to prepare a flow chart. A flowchartis a schematic representation of an algorithm or a stepwiseprocess, showing the steps as boxes of various kinds, and theirorder by connecting these with arrows. Flowcharts are used indesigning or documenting a process.

What is the mass of 7.675 x 1023 atoms C? Answer in units of g.
nalin [4]

Answer: 15.3 grams C

Explanation:  1 mole is 6.02x10^23 atoms.  We can find the moles of C in 7.675 x 10^23 atoms of C by dividing:

(7.675 x 10^23 atoms C)/(6.02x10^23 atoms C/mole) = 1.275 moles C

The molar mass of carbon is 12g/mole.  So the mass of 7.675 x 10^23 atoms is (1.275 moles C)*(12 g/mole C) = 15.3 grams.

It is the solution, with more amount of solute than the solvent , is known as hypertonic solution.

Now, is some substance is immersed in such solution , the substance gets shrinked , because , the solvent from the substance moves out of it and moves to the hypertonic solution.

Hence, the pickles gets shrinked up , as they put in a hypertonic solution.
