For the purpose, we will use the equation for determining the dissociation constant from concentration and <span>percent of ionization:
Kd = c </span>× α²
α = √(Kd/c) × 100%
Kd = 6.0×10⁻⁷
c(HA) = 0.1M
α = √(6.0×10⁻⁷/0.1) × 100% = 0.23%
So, in the solution, the acid <span>percent of ionization will be just 0.23%.</span>
Answer:
2 electrons
Explanation:
Oxygen has 6 valence electrons and to be stable it needs 8. That means it needs 2 more electrons to have a full octet.

An atom of this isotope contains 5 protons and 10-5=5 neutrons.

The answer is A. 1.67 × 10⁻²⁶ kg.
1 tablespoon = 0.5 ounces
We are required to find for 2 table spoons.
2 table spoons = 2 x 0.5 = 1 ounce.
Each bottle has 16 ounce.
Number of bottles = 4
So total number = 4 x 16 = 64 ounces.
Number of 2 table spoons = 
= 64
Thus there are 64 2-tablespoon doses are in 4 bottles of medication containing 16 ounces each.
