Answer:
Option B
Explanation:
Given elements are F, S, Ca, K
Assuming that the order of ionization energies is asked for first ionization energy
Ionization energy is defined as the minimum energy required to remove an electron from its valence shell
Among these elements K will have least ionization energy because it requires minimum energy to remove an electron form its outer most shell as after removing the valence electron it will gain octet configuration, therefore it wants to loose that valence electron
Among the given elements F has maximum ionization energy because of its small size and high nuclear charge and due to this maximum amount of energy is required to remove the valence electron
While comparing between Ca and S, S has maximum ionization energy because of its small size and high nuclear charge
∴ Order is K < Ca < S < F
Answer:
Different atmospheric pressure. When there is a different atmospheric pressure, air moves from the higher pressure to the lower pressure area which results in what you call <u>WIND</u> but can result in various speeds and pressure.
Hope this helped and if it did, please give my answer a brainliest.
A cookie made from flour, eggs, sugar, butter, and chocolate chips is an example of a heterogeneous mixture.
Also, mixing the sugar flavoring in water, since you're mixing two different states of matter.
Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation (![[\alpha]](https://tex.z-dn.net/?f=%5B%5Calpha%5D)
) = 
where, 
= observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c = 
= 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation () =
= 
= 
Thus, we can conclude that the specific rotation of this compound is .
