Answer:
pH = 4
Solution is acidic
Explanation:
Given data;
Hydronium ion concentration = 1 × 10⁻⁴ M
pH of solution = ?
Solution:
pH = -log [H₃O⁺]
pH = -log [ 1 × 10⁻⁴ ]
pH = 4
According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.
Answer:
C3H6 + Br2 → C3H6Br2
Explanation:
The reaction in which C3H6Br2 (1,2-Dibromopropane) is created is:
We can see that the only difference between the product (C3H6Br2) and the known reactant (C3H6) of the reaction is two bromine atoms (Br2). Br2 is diatomic bromine - a molecule we get after combining two bromine atoms. This compound is a red-brown liquid at room temperature, which means that that is the liquid described in your question.
Answer:
NaCl: ionic, HF: hydrogen bond, HCl: dipole dipole , F2: dispersion force
Explanation:
complete question is:
The four major attractive forces between particles are ionic bonds, dipole-dipole attractions, hydrogen bonds, and dispersion forces. Consider the compounds below, and classify each by its predominant attractive or intermolecular force among atoms or molecules of the same type.Identify each of the following ( NaCl, HF, HCl, F2) as Ionic, H Bonding, Dipole or Dispersion.
Answer:
The correct option is: "Vitamin B12 (cobalamin) is not found in the vegan diet and is very low in the lacto-vegetarian diet"
Explanation:
Homocysteine is a VERY IMPORTANT type of amino acid, a chemical that the body uses to make proteins. Normally, vitamin B12, vitamin B6, and folic acid break down homocysteine and transform it into other substances that the body needs. There should be very little homocysteine left in the bloodstream. If you have high homocysteine levels in your blood, that could be a sign of a vitamin deficiency of the vitamins listed above, a heart condition, or a rare inherited disorder.
First, we will get the average pH of the two given values:
average pH = (6.4+8) / (2) = 7.2
At this average pH, the concentration of the acid from the phenol red is equal to the concentration of the base.
pH = 7.2
[H+] = 10^(-7.2) = 6.3 * 10^-8
Phenol red has the general formula HA, this gives us:
HA <.......> H+ + A-
At pH = 7.2, [H+] = [A-]
<span>Ka = [H+][A-]/ [HA]
</span>Ka = [H+] = <span>6.3 x 10^-8</span>
