Answer:
Correct answers: 2 and 3
Explanation:
1- correct would be: Isolation of ibuprofen is not dangerous, but it is necessary because only one enantiomer has effect on interaction with biologic <em>diana</em>
<em>2: Correct! This property of diastereomeric salts (differing solubilities) is really useful for the isolation of the original enantiomers</em>
<em>3: Correct! we can only observe their properties, like polirized light rotation or separation in an assimetric column for chromatography.</em>
4: correct would be: diastereomeric salts do not rotate light, they have lost the property of anantiomers that originated them
Radio waves infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
Answer:
Bond angle is defined as the angle between two or more bonds or bonded electron pairs in a compound.
Explanation:
a) O−O−O angle of O3 - <120°
b) F−B−F angle of BF3 - 120°
c) F−O−F angle of OF2 - <109.5
d) Cl−Be−Cl angle of BeCl2 - 180°
e) F−P−F angle of PF3 - 109.5°
f) Cl−Si−Cl angle of SiCl4 - 90°
Answer:
A transition metal
Explanation:
The metal is classified as a transition metal or transition element.
In particular, this atom is Copper it has an atomic number of 29 which we know by the number of protons.
The number of protons in an atom is the same as the atomic number.
- The element can be found in the d-block on the periodic table.
- Generally, it is classified as a transition metal.
- A neutral atom of this element has 29 electrons.
