Hmm trick question here's my answer: the content: protons charge the electrons into its usage , the size: 1.6fm if I'm wrong sorry if I'm right: HA IN YOUR FACE HA!!!
The concentration (in M) of hydroxide ions in a solution at 25°C with a pOH of 3.58 is 2.6 × 10⁻⁴ M.
pOH is the measure of basic nature of a solution by evaluating the [OH⁻] concentration.
It is the negative logarithm of the hydroxide ion concentration.
Given,
pOH = 3.58
Temperature = 25°C = 298K
At 25°C, the relation of pOH and [OH⁻] concentration is as follows:
∴ pOH = -log [OH⁻]
⇒ 3.58 = -log [OH⁻]
⇒log [OH⁻] = -3.58
⇒ [OH⁻] = antilog (-3.58)
⇒[OH⁻] = 2.6 × 10⁻⁴ M
The concentration (in m) of hydroxide ions in a solution at 25.0 °C with a pOH of 3. 58 is 2.6 × 10⁻⁴ M.

Positively charged and the sodium ion would be a cation
Answer:
higher, higher
Explanation:
It takes more energy to rip apart stronger bonds (that's mostly just common sense there). The boiling point increases because it would take more energy to get the molecules to go from a stuck together liquid, to separating in a gaseous form.
<h3><u>Answer;</u></h3>
<em>D. Have different structures and different functions</em>
A plasma membrane and a cell wall <em><u>have different structures and different functions</u></em>.
<h3><u>Explanation;</u></h3>
- <em><u>Plasma membrane</u></em> is a structure that is found in <u><em>both animal cell and plants cells</em></u>. It is made up of a <u><em>bi-layer consisting of lipid and proteins</em></u>. Plasma membrane are semi-permeable which means the<em><u> allow selective movement of materials in and out of the cell. </u></em>
- <em><u>Cell wall</u></em>, on the other hand is a structure that is found on plant cells and lacks in animal cell. It <em><u>contains cellulose in its structure </u></em>which enables it to be rigid and enhances it <em><u>protect the cell from mechanical damage</u></em> from harsh conditions such as pressure in the outside environment.
