Chemistry
1 answer:
trasher [3.6K]3 years ago
8 0

Answer: Option (a) is the correct statement.

Explanation:

A substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass is known as a compound.

For example, Ca + Cl_{2} \rightarrow CaCl_{2}

Here, CaCl_{2} contains one atom of calcium and two atoms of chlorine which are chemically combined together in 1:2 ratio. Therefore, it is a compound.

Also, both chemical and physical properties of CaCl_{2} will be different from Ca and Cl_{2}.

Thus, we can conclude that the statement atoms are bonded together, and the compound has different physical and chemical properties than the individual element, is correct.

Essential amino acids
Amino acids are the molecules that make up proteins when they are linked up. There are certain essential amino acids, namely they are <span>histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
All of these must be obtained from one's diet. If they are not, the body will use existing proteins, such as muscle mass, to obtain them.</span>

A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided
Mademuasel [1]

A measure of peak separation in a chromatographic method that equals the difference in retention time for two components divided by the average of their peak widths is the definition of resolution.

Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.

The analyte's interaction with the stationary phase determines the longer retention period.

The duration of retention will increase as the interaction becomes more strong.

Resolution is defined as the peak separation in a chromatographic procedure that is equal to the difference in retention time for two components divided by the average of their peak widths.
