Answer:
D-Glucose and L-Glucose
Explanation:
Aldohexose are the sugars which have six number of carbons and ends up in having an aldehyde group at one end. When dilute nitric acid is treated with any of them, the molecule gets oxidized (gets oxygen) and therefore turns into carboxylic acid.
The name of A is D-Glucose, and B is L-Glucose. Please find the structural formula attached.
MgCl2 is an ionic compound because chemical bonds in the molecule are formed by the transfer of electrons among Mg and Cl atoms.
<h3>What is chemical bond ?</h3>
A chemical bond is a strong bond that can be formed between atoms, ions, or molecules to create chemical compounds. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds."
The positively charged protons in the nucleus and the negatively charged electrons in its orbit are attracted to one another by the basic electromagnetic force.

Nucleotides are the building blocks of nucleic acids, as they are essential for the making of the acid
<u>Correct Answer:</u><u> Option (A) </u>
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
Explanation:
The mole ratio is the ratio of coefficients of the compounds involved in the reaction. <u>R</u><u><em>eactants,</em></u><u> as on the left hand side of the chemical reaction which reach to for</u>m new products.
In the given reaction,
2H₂S + 3O₂ ⇒ 2SO₂ + 2H₂O
<u>The reactants are :</u> H₂S (hydrogen sulphide) & O₂ (oxygen)
<u>The products are :</u> SO₂ (sulphur dioxide) & H₂O (water)
- 2 moles of hydrogen sulphide react with 3 moles of oxygen
- 2 moles of sulphur dioxide & 2 moles of water are produced
Therefore correct option is
H₂S : SO₂ = 2:2 and,
O₂: H₂O = 3:2
Answer:
570
Explanation:
569.8's nearest number is 570 because "9.8" is closest to the whole number.
