<h2>Answer with explanation:</h2>
<em><u>Beer's Law is described as if a light passes from a solution, the concentration of the solution is directly proportional to the absorbance of light by that solution.</u></em>
Every element has a definite of absorbance of light.
In the testing of food, drugs or in medical testing, the light is passed from the sample.
Them transmitted light from these samples are measured. The difference between target light amount and transmitted light is the amount of absorbed light.
From this absorbed light value, we can identify an element in sample and its quantity.
Spectrophometry is based on this law.
The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms
It has many different uses like being used to make the tube of a vacuum cleaner and also can be used to make oil in space crafts.
Answer is: CaCl₂(s), calcium chloride.
Calcium cations and chlorine anions have a crystal structure in this solid inorganic salt. Ions have <span>the ordered arrangement.</span><span>
Ethane (C</span>₂H₆) is gas, g is chemistry
abbreviations or physical state symbol for gas, gases do not have a crystal structure.
Methanol (CH₃OH) is liquid, l is chemistry abbreviations or physical state symbol for liquids, it do not have a crystal structure.
Calcium iodide is dissolved in water, aqueous solution
(aq) do not have a crystal structure.
Answer:
Proteins
Explanation:
Amino acids act as monomers (a single unit used to form polymers) , the polymer will be a long chain of individual amino acids. An amino acid chain forms a protein. These proteins are also known as peptides.
