Answer:
Because the most reactive elements are<em> HALOGENS</em>.
Answer:It is a gas because its particles move in many different directions.
Answer:
60 mL
Explanation:
200 mL = 0.2 L
We know that:
Molarity = Moles / Liters
So:
4.20 M = moles / 0.2 L
moles = 4.20 x 0.2 = 0.84
Then:
14.0 M = 0.84 moles / Liters
Liters = 0.84 moles / 14.0 M = 0.06 L
Since they want the answer in mL, convert 0.06 to get 60 mL
(1.632) (4.0 x 104)
= (1.632)(416)
=678.912
6.8* 10^2.
Not sure if it's the right sig figs.
In Chemistry, the dissociation constant describes a dissociation reaction in which a compound is broken up. It measures how likely the reaction will occur. For example for reaction AB -> A + B, the dissociation constant is equal to concentration of A x concentration of B / concentration of AB at equilibrium.
