Answer:
Following are the responses to the given question:
Explanation:
Since HN03 is an oxidation substance D-ribose u.ith oxidized to form in rubric acid Ribose is chiral, but rubric acid is achiral because of its symmetry mirror level, Hence no infrared roster in the sample holder is observed.
Please find the attached file.
D-Arabinose, on either hand, gives optical aldaric acid with such a net optical rotation observed inside the polarimeter for diagnosis with HN03.
23.227 grams of NO is formed upon the complete reaction of 31.0 grams of oxygen gas with excess ammonia.
Explanation:
The balanced chemical equation is:
4NH3 + 5O2 ⇒ 4NO + 6H20
Number of moles will be calculated.
31 grams of oxygen is given
atomic weight of oxygen gas i.e O2 = 32gm/mole
The molar mass of oxygen gas is 32 grams/mole which is equal to one mole of the molecule.
Number of moles (n) =
n=
n = 0.968 moles of oxygen are given for the reaction to occur.
From the balanced chemical equation it can be seen
5 moles of oxygen yielded 4 moles of NO
So, 0.968 moles of oxygen yield x moles of NO
=
4 × 0.968 =5x
x = 0.774 moles of NO will be formed.
To calculate the mass of NO
mass= atomic mass x number of moles
atomic mass of NO is 30.01 grams/mole
putting the values in the formula:
mass = 30.01 x 0.774
= 23.227 grams of NO is formed.
