Answer,
For example, silver ion can be precipitated with hydrochloric acid to yield solid silver chloride. Because many cations will not react with hydrochloric acid in this way, this simple reaction can be used to separate ions that form insoluble chlorides from those that do not.
Answer:
2.5 atm
Explanation:
P2 = 1.2 atm x 2.65 L x 345 K / 1.5 L x 298 K

Answer:
B) Because you are adding positively charged protons, which pull in the outer electrons.
Explanation:
Since the increase in protons have a greater effect then the increase in electrons the protons pull the electrons in closer resulting the radius of an atom to decrease from left to right across a period.
The pOH of a solution with [OH] = 9.0 × 107 will be D (6.04).
<h3>What is ph value?</h3>
A ph value is the measure of acidity and the basics of a substance or solution.
Given;
[OH] = 9.0 × 10^7
pOH = - log [OH⁻]
pOH = - log (9.0 x 10⁻⁷)
pOH = 6.0457
Hence, The pOH of a solution with [OH] = 9.0 × 107 will be D (6.04).
