Answer:
21.60% is the percent ionization of a 0.123 M solution of this acid.
Explanation:
The equilibrium reaction for dissociation of weak acidis,

initially conc. c 0 0
At eqm.
Concentration of the weak acid (c) = 0.123 M
Acid dissociation constant = 
Degree of ionization of weak acid = 
An expression of dissociation constant is given as:



Percent ionization of weak acid:


Answer:
001: 71.2 g per ML
002: Consider a block of marble that occupies 287 cm3 and has a mass of 869 g.
a. What is its density?
d=m/v=869g/287 cm3=3.03 g/cm3
b. Will it float in:
H2O(l)? Why or why not?
Nope! Density > 1.00 g/mL
Hg(l) (density=13.55 g/mL)? Why or why not?
Yep! Density < 13.55 g/mL
003:
Use the given functions to set up and simplify
0.309 cm3
g/cm3=g/cm3
0.309cm3=g/cm3

Hope this helps I tried my best
Answer:
I think it's because he was presumed dead after a storm, or like a problem with his suit
Calcium carbonate when mixed with water result in the
formation of Calcium hydroxide which is used as an antacid. The chloride ion
also helps in the whitening of teeth thus finding its use as an ingredient in toothpaste.
Iron oxide is dark pigment which is naturally used in
makeup.
<span>Therefore the
answer to this question is
Swap the uses for iron oxide and calcium
carbonate. </span>
