Answer:
The symbol of the Element is simply just the abbreviation.
Mercury: Hg
Potassium: K
Nitrogen: N
Copper: Cu
Sulphur: S
Carbon: C
Chlorine: Cl
Oxygen: O
The number of unpaired valence electrons determine the radical in any element.
Mercury: Hg 2+
Potassium: K+
Nitrogen: N 2+
Copper: Cu 2+
Sulphur: S 2-
Carbon: C 4+
Chlorine: Cl -
Oxygen: O 2-
Glad I could help. Thanks for the question! Have a great day, and feel free to mark this brainliest!
The ionization equation is:
HF ⇄ H(+) + F(-)
The ionization constant is Ka = [H(+)] * [H(-)] / [HF]
=> [H(+)] * [F(-)] = Ka * [HF]
Given that Ka < 1
[H(+)] * [F(-)] < [HF]
Which is [HF] > [H(+)] * [F(-)] the option a. fo the list of choices.
Answer:1.01
Explanation:∆G(system)= ∆G(product) - ∆G(reactant)
Therefore, we have: -32 - 209.2 = -242.09 kj/mol.
Also, ∆G(system)= -RT ln kp ----{*}
R= 8.314, T= 298, kp =? , ∆G(system)= -242.09 kj/mol.
We can now substitute into equation {*}.
I.e, -242.09kj/mol= -8.314×298 ln kp
-242.09= -24477.572 ln kp
In kp= - 242.09÷ -24477.572
ln kp= 0.00989
kp= 1.0099.

Explanation:
The alkaline earth family is the second most reactive group, and it's elements can't be found free in nature. They are called "alkaline" earth metals because they form "alkaline" solutions, hydroxides, when they react with water
