It is the same like the aldaric acid of L-Allose because the top and bottom groups are the same we can rotate it without changing the configuration
check the attached picture:
- The structure is in Meso form so both compound and its mirror image have the same structure (optically inactive)
Answer:
Nitrogen, water
Explanation:
"Most common nonmetallic substances such as halogens, halogen acids, sulfur, and phosphorus react with the alkali metals."
B. the physical properties have changed, but the chemical properties have not.
Carbonic acid (H₂CO₃) dissociation in water takes place in 2 steps. its a polypro tic acid as it has 2 H⁺ ions it can donate.
the dissociation reactions in water are as follows;
H₂CO₃ + H₂O ---> HCO₃⁻ + H₃O⁺
in the first dissociation it releases a proton that combines with water to form a hydronium ion.
HCO₃⁻ + H₂O ----> CO₃²⁻ + H₃O⁺
second dissociation results in the carbonate ion and hydronium ion formation.
As the ratio of acid dissociation constant ka1/ka2 > 10⁴ , dissociation takes place in 2 steps.
