The pH of the solution is 4.38.
<h3>What is the pH?</h3>
The first thing that we must do is to set up the ICE table for the reaction as shown;
Given that;
HA = 1.8 M
HA(aq) + H2O(l) ⇔ H3O^+(aq) + A^-(aq)
I 1.8 0 0
C - x +x +x
E 1.8 - x x x
K = [H3O^+] [A^-]/[HA]
9.55 × 10^−10 = x^2/0.0158 - x
9.55 × 10^−10(1.8 - x ) = x^2
1.719 * 10^-9 - 9.55 * 10^-10x = x^2
x^2 + 9.55 * 10^-10x - 1.719 * 10^-9 = 0
x=0.000041 M
pH = -log(0.000041 M)
pH = 4.38

Answer:
which following give options
Answer:
your answer is 30f
Explanation:
The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.
The following directions for diluting a 10.0 M answer to a 1.00 M solution is no longer correct.
<h3>.What is the rule of dilution?</h3>
A popular rule to use in calculating the attention of solutions in a sequence is to multiply the unique concentration by means of the first dilution factor, this by the second dilution factor, this by the 1/3 dilution factor, and so on till the ultimate attention is known.
Example: A 5M answer of HCl is diluted 1/5.
<h3>How do you do a 1 in 10 dilution?</h3>
For example, to make a 1:10 dilution of a 1M NaCl solution, you would combine one "part" of the 1M solution with 9 "parts" of solvent (probably water), for a total of ten "parts." Therefore, 1:10 dilution ability 1 part + 9 components of water (or different diluent).
