<em>Reasons why a 100% yield is not obtained in actual chemical manufacturing processes may be;</em>
- The reactor has a certain capacity to produce a certain yield
- There is a limiting reactant that runs out and the reaction can not proceed any further
It may also be because the reaction is reversible or because of loses of desired product during isolation and purification.
Answer:
Is there a picture To go with this?
Explanation:
Answer:
Explanation:
I searched it up:
"The Heisenberg uncertainty principle states that the exact position and momentum of an electron cannot be simultaneously determined. This is because electrons simply don't have a definite position, and direction of motion, at the same time! ... We know the direction of motion."
Hope this helps :D
Answer:
Most positive = rubidium
Most negative = fluorine
Explanation:
Electron affinity of an element is the energy released when an electron is attached to a neural atom to form an ion in its gaseous state.
X + e⁻ → X⁻
Electron affinity is similar to electronegativity which is the tendency at which an atom accepts an ion towards itself.
Electron affinity increases across the period and decreases down the group in the periodic table.
In the above option,
Fluorine has the highest electron affinity
Rubidium has the lowest electron affinity
Tellurium and then finally Phosphorus
Helium in this case would have the lowest electron affinity because it has filled orbital and does not require any electron to attain stability. Technically, Helium has the lowest or is expected to have the lowest electron affinity which is close to zero according to quantum mechanics.
Most positive = rubidium
Most negative = fluorine.
You can check periodic table for their exact values
