Answer:
Physical property
Explanation:
We can visualize the property without the need to do any experiments.
Answer:
11.7
Explanation:
The pH is the negative logarithm of the concentration of H+ ions. If the concentration is 2×10-¹² the the pH will be -log(2×10-¹²) which is 11.698 which can be round up to 11.7.
I do believe the answer is A. I'm sure
Arrhenius is a substance that dissociates in water to produce hydrogen ions (H+) and there is a clear answer which coincides with this definition. The correct answer is definitely b. a substance that increases the concentration of hydronium ions when dissolved in water.
3*40+3*2*35.5=333* Avogadro’s number =
1.98*10^25
