Answer:
[OH-] = 1.08x10^-11 M
Explanation:
From the question given,
Concentration of Hydrogen ion, [H+]
= 9.3x10^-4 M
Concentration of Hydroxide ion, [OH-] =..?
The concentration of the hydrogen ion, [H+] and hydroxide ion, [OH-] are related with the following formula:
[H+] x [OH-] = 1x10^-14
Using the above formula, we can easily calculate the concentration of the hydroxide ion, [OH-] as follow:
[H+] x [OH-] = 1x10^-14
[H+] = 9.3x10^-4 M
9.3x10^-4 x [OH-] = 1x10^-14
Divide both side by 9.3x10^-4
[OH-] = 1x10^-14 /9.3x10^-4
[OH-] = 1.08x10^-11 M
Answer: HF-dipole- dipole interaction
CH3OH- dipole-dipole interaction
CaCl2- ion-ion interaction
Explanation:
Both CH3OH and HF possess permanent dipoles which interact with water leading to the dissolution of the above named substances. Remember that water also possesses a permanent dipole. Which can interact with the dipoles on other polar molecules. CaCl2 is purely ionic and interacts with water via ion-dipole mechanism.

The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
Radon is a naturally radioactive gas generated from different elements such as uranium or radium.
Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.
Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.
