Answer:

Distillation

Explanation:

Distillation is a process known long ago and according to some authors was created by the Alchemists at a time where Chemistry was not yet recognized as Science and was closely linked to religious precepts.

Basically the distillation process is a process of physical separation and is used to separate homogeneous mixtures from heating. To separate a solid-liquid type mixture we use simple distillation and to separate liquid-liquid mixtures we use fractional distillation.

Answer:

Distillation

Explanation:

If the solute is a solid or a liquid with a boiling point at least 30 °C different from that of the solvent, you can use the technique of distillation.

The solvent will boil before the solid or a higher-boiling liquid.

A liquid solute with a lower boiling point than the solvent will boil off first, and then you can distill off the solvent.

Which statement below correctly describes how amino acids join?
Shtirlitz [24]

Answer:

Amino acids join by linking the acid group of one amino acid to the amino group of another.

Explanation:

Amino acids are organic molecules that form the basic molecules for making proteins and there are. An amino acid comprises of an acidic carboxyl (-COOH) functional group and an amino group (-NH2)  as well as a side an organic side chain (R group).

In the formation of proteins, several amino acids join together by the formation of peptide bonds between each amino acids to form a long polypeptide. These peptide bods are formed by the linking of the acidic carboxyl group of one amino acid to the amino group of another amino acid, during this process water is removed.

Calculate the mass percent (m/m) of a solution prepared by dissolving 51.56 g of NaCl in 164.2 g of H2O. Express your answer to
denis-greek [22]

Answer:

"23.896%" is the right answer.

Explanation:

The given values are:

Mass of NaCl,

= 51.56 g

Mass of H₂O,

= 165.6 g

As we know,

⇒  Mass of solution = Mass \ of \ (NaCl+H_2O)

                                 = 51.56+164.2

                                 = 215.76 \ g

hence,

⇒ Mass \ percent =\frac{Mass \ of \ NaCl}{Mass \ of \ solution}\times 100

                           =\frac{51.56}{215.76}\times 100

                           =23.896 \ percent
