Chemistry
1 answer:
Alex3 years ago
4 0

Answer:

see below

Explanation:

1. Heat energy is added to the substance, weakening the electrical attraction between molecules.

2. Both the melting point and boiling point are lower.

3. dipole

4. Water and ethanol have different molecular structures.

5. The lone pairs of electrons in the oxygen atom causes the molecule to be bent; the oxygen atom has a partial negative charge, while the hydrogen atoms have partial positive charges.

If you have a pH of 3.35, what is the hydrogen ion concentration of the solution?
melamori03 [73]

Answer: 4.46 x 10^-4M

Explanation:

The pH of a solution is the concentration of hydrogen ion concentration in the solution. Mathematically, it is expressed as pH = -log(H+), where H+ is the concentration of hydrogen ion

On the pH scale, readings are from 1 to 14.

- pH values less than 7 are regarded as acidic. So, the solution with pH 3.35 is said to be acidic, and will produce hydrogen ions.

3.35 = -log(H+)

(H+) = Antilog (-3.35)

(H+) = 0.000446M

Place (H+) in standard form

(H+) = 4.46 x 10^-4M

Thus, the concentration of hydrogen ion in the solution with pH 3.35 is 4.46 x 10^-4M
