Answer: The mole ratio of D : A is 3 : 2.
Explanation: Mole ratio for a chemical reaction is the ratio of their respective stoichiometric numbers or the ratio of their moles in a chemical reaction.
For a given chemical reaction:
By stoichiometry,
2 moles of A is reacting with 1 mole of B to produce 1 mole of C and 3 moles of D.
So, Mole ratio of D is to A will be 3 : 2
Particles in a gas are far apart compared to a solid or liquid, allowing it not to have a definitive shape or volume. This also means that gases can fill any container and be easily compressed.

Answer:
Positive, Negative
Explanation:
The charge of an amino acid is dependent on pH values of their pKa's. At pH 7, Basic amino acid will be positive because they have pH values below their pKa's while an R group amino acid will be negative
