The answer to your question is false
Answer:
they condensate
Explanation:
for the example let's use water vapor when gas particles are cooled down they slow done and then they change the state of matter in this case it turns into a liquid hope this helps
Answer:
1.40 M [OH⁻]
Explanation:
This compound dissociates into 3 ions, but since we are asked about [OH⁻], it's only 2. Therefore, multiply the molarity of the solution by the number of ions that [OH⁻] dissociates into:
2 × 0.70 M = 1.40 M
Hope this helps! Sorry that you got a link. Those are getting really annoying

The pH of the solution is obtained as 2.23.
<h3>What is the pKa?</h3>
The pKa shows the extent to which an acid is dissociated in solution. Now we have;
HCOOH(aq) + H2O(l) ⇔ HCOO-(aq) + H30+(aq)
Ka = [HCOO-] [ H30+]/[ HCOOH]
But = [HCOO-] = [ H30+] = x
Ka = x^2/[HCOOH]
x = √Ka [HCOOH]
x = √0.19 * 1.8×10−4
x = 5.8 * 10^-3
pH = - log (5.8 * 10^-3)
pH = 2.23
