Imporance of mixture in our daily life​
garri49 [273]

Answer:A mixture is a mechanical combination of several elements or compounds. Mixtures are used in cooking, chemical manufacturing, and a lot of other processes. A good mixture with the materials evenly distributed facilitates a good after mixture process. That might be a chemical reaction or a great cake. One mixture that we see the results of a lot is the mixture of water, gravel, and Portland cement that, after a good mix, becomes concrete. Other mixtures might include the various plastics and epoxies that require two or more parts to become a finished product. There are so many possible mixtures out there I’d suggest chemical engineering books , chemistry books in general, cook books, books on construction processes, and many other possible sources of mixtures and the results of using them.

Draw the Lewis structure (including all lone pair electrons and any formal charges) for one of the four possible isomers of C3H9
Alexus [3.1K]

Answer and Explanation

The isomer picked is the N-Propylamine.

It has a lone pair of electron available on the electron rich Nitrogen and no formal charge.

Since it will be hard to draw the Lewis structure in this answer format, I'll attach a picture of the Lewis structure to this answer.

The lone pair of electron is shown by the two dots on the Nitrogen atom.
