The job outlook for physical therapists<u> "will improve over time".</u>
Physical therapists, help harmed or sick individuals enhance their development and deal with their agony. These therapists are frequently an imperative piece of the restoration, treatment, and counteractive action of patients with unending conditions, ailments, or wounds.
Physical therapists commonly work in private workplaces and centers, clinics, patients' homes, and nursing homes. They invest quite a bit of their energy in their feet, effectively working with patients.

Explanation:
Answer:
Iodine
Explanation:
It's in the same group as chlorine.
The answer is Ka = 1.00x10^-10.
Solution:
When given the pH value of the solution equal to 11, we can compute for pOH as
pOH = 14 - pH = 14 - 11.00 = 3.00
We solve for the concentration of OH- using the equation
[OH-] = 10^-pOH = 10^-3 = x
Considering the sodium salt NaA in water, we have the equation
NaA → Na+ + A-
hence, [A-] = 0.0100 M
Since HA is a weak acid, then A- must be the conjugate base and we can set up an ICE table for the reaction
A- + H2O ⇌ HA + OH-
Initial 0.0100 0 0
Change -x +x +x
Equilibrium 0.0100-x x x
We can now calculate the Kb for A-:
Kb = [HA][OH-] / [A-]
= x<span>²</span> / 0.0100-x
Approximating that x is negligible compared to 0.0100 simplifies the equation to
Kb = (10^-3)² / 0.0100 = 0.000100 = 1.00x10^-4
We can finally calculate the Ka for HA from the Kb, since we know that Kw = Ka*Kb = 1.0 x 10^-14:
Ka = Kw / Kb
= 1.00x10^-14 / 1.00x10^-4
= 1.00x10^-10
