Bacteria can’t live without humans
Answer:
<u>The direction of dipole moment is C→Cl and electronegativity difference = 0.5</u>
Explanation:
The dipole moment is formed when there is a separation of charges in a chemical bond. The electrons of the bond tend to be more localized near the more electronegative atom.
The electronegativity of chlorine atom = 3.0 and electronegativity of carbon atom = 2.5
Therefore, chlorine is more electronegative than carbon. So, the electrons tend to be localized more near the electronegative chlorine atom. <u>Therefore, the direction of dipole moment is C→Cl and electronegativity difference is equal to 0.5.</u>
Cl₂
Explanation:
The gas with the highest molecular mass will be considered the heaviest of all of them.
To solve this problem, we must calculate the molecular mass of the given gases;
O₂ CH₄ CO₂ and Cl₂
O₂ molecular mass = 15.9998 x 2 = 32g/mol
CH₄ = 12 + 4(1) = 16g/mol
CO₂ = 12 + 2(16) = 44g/mol
Cl₂ = 2(35.5) = 71g/mol
The heaviest of the gases given is Cl₂ because it has the highest molar mass compared to other gases.

Once <u>hydrogen</u> bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the <u>secondary</u> structure known as a(n) <u>alpha helix</u>.
<h3>
What is Amino Acid ? </h3>
Amino acids are organic compound. Amino acids contains amine and carboxyl functional group. Amino acids is the building block of life these are the molecules that combine to form proteins.
<h3>What is Polypeptide Chain ? </h3>
A unique sequence of amino acids joined by peptide bonds is called polypeptide.
Thus from the above conclusion we can say that Once <u>hydrogen</u> bonds form between every fourth amino acid in a polypeptide chain, the chain begins to twist into the <u>secondary</u> structure known as a(n) <u>alpha helix</u>.
