Answer:
See picture and explanation below
Explanation:
In the attached picture you have the answer for this.
In the first step, we have an acid base reaction between HCN and NaOH. When this happens, its formed the following:
HCN + NaOH --------> CN⁻ + H₂O + Na⁺
As a second step, The CN⁻ attacks the carbonile group in the cyclopentane. This causes to open the double bond, and then, the Cyano enters the molecule.
The final step is another acid base reaction, where the oxygen substracts a hydrogen atom of the water in the medium, and then, the alcohol group is formed. With this step, the cyanohydrin is finally formed. See the mechanism below in the picture.
Hope this helps
Answer: Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.
so C would seems to be right.
Explanation: The energy of an electron depends on the size of the orbit and is lower for smaller orbits. Radiation can occur only when the electron jumps from one orbit to another. The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.
Answer:
producing colored sparks in fireworks and rusting in the presence of water and oxygen
Explanation:
yeet
Physical change .. you cannot undo chemical ... physical is like bending , shattering a mirror , denting something ..
chemical would be rust or something .
