Answer:
- <u>Alkaline or basic solution </u>(alkaline and basic means the same)
Explanation:
According to the <em>pH</em>, solutions may be classified as neutral, acidic, or alkaline (basic).
This table shows such classification:
pH classification
7 neutral
> 7 alkaline or basic
< 7 acidic
Thus, since the pH of the solution is 8.3, which is greater than 7, the solution is classified as basic (alkaline).
Additionally, you must learn that pH is a logarithmic scale for the concentration of hydronium ions in the solution.
- pH = - log [H₃O⁺]
You can calculate the concentration of hydronium ions using antilogarithm properties:
NaOH solutions are alkaline solutions, bases, according to Arrhenius model, because they contain OH⁻ ions and release them when ionize in water.

Explanation:
Hello,
Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:
Nevertheless, since we've got a angled force, it becomes:
In this case, accounts for the formed angle, so the horizontal acceleration turns out into:
