Answer:
If this is a True or False question the answer is False
Answer:
"The strength of ionization decreases as the proportion including its protons to the excited electrons" is the right solution.
Explanation:
- The ionizing procedure, the creation of ions through manipulating individual atoms or revolutionaries, or through decreasing or increasing charged particles in something other than gas by intense electrical fields.
- It should be the total removal of someone with an electron through an atomic nucleus rather than from molecules. The corresponding molecule has denominated an ion.
It's D, all of the claims are true about oxidation reactions :)
Answer is: pH value of weak acid is 3.15.<span>
Chemical reaction: HA(aq) </span>⇄ A⁻(aq) + H⁺<span>(aq).
c(weak acid) = 0,5 M.
Ka(weak acid) = 1.0</span>·10⁻⁶.
[A⁻] = [H⁺] = x.
[HA] = 0.5 M - x.
Ka = [A⁻]·[H⁺] / [HA].<span>
</span>1.0·10⁻⁶ = x² / (0,5 M - x).
Solve quadratic equation: x = [H⁺] = 0.0007 M.
pH = -log[H⁺].
pH = -log(0.0007 M).
pH = 3.15.
Explanation:
High density medium to low density medium.
