Answer:
A. C₃H₄N
Explanation:
- Firstly, we need to calculate the no. of moles of C, H, and N using the relation:
<em>no. of moles = mass/molar mass.</em>
<em></em>
∴ no. of moles of C = mass/molar mass = (90.0 g)/(12.0 g/mol) = 7.5 mol.
∴ no. of moles of H = mass/molar mass = (11.0 g)/(1.0 g/mol) = 11.0 mol.
∴ no. of moles of N = mass/molar mass = (35.0 g)/(14.0 g/mol) = 2.5 mol.
- We should get the mole ratio of each atom by dividing by the lowest no. of moles (2.5 mol of N).
∴ the mole ratio of C: H: N = (7.5 mol/2.5 mol): (11.0 mol/2.5 mol): (2.5 mol/2.5 mol) = (3: 4.4: 1) ≅ (3: 4: 1).
- So, the empirical formula is: A. C₃H₄N.
Answer :
Amino acids join by forming (1) peptide bonds. Water is released.
The chains of amino acids vary according to their (2) side chains, which each have differing makeup.
These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.
Explanation :
Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine
and carboxylic
groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.
Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.
Some examples of amino acids are glycine, lysine, alanine, etc.
Peptide bond formation image is shown below.
In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc
