Answer:
The liquid is likely to be a base e.g Sodium hydroxide solution or Ammonia solution
Answer:
7.41 × 10⁻⁵
Explanation:
Let's consider the basic dissociation reaction of trimethylamine (CH₃)N).
(CH₃)N + H₂O = (CH₃)NH⁺ + OH⁻
According to Brönsted-Lowry, in this reaction (CH₃)N is a base and (CH₃)NH⁺ is its conjugate acid. The pKb for (CH₃)N is 9.87. We can calculate the pKa of (CH₃)NH⁺ using the following expression.
pKa + pKb = 14
pKa = 14 - pKb = 14 - 9.87 = 4.13
Then, we can calculate the acid dissociation constant for (CH₃)NH⁺ using the following expression.
pKa = -log Ka
Ka = antilog - pKa = antilog -4.13 = 7.41 × 10⁻⁵
One way of expressing concentration is by molarity. It is the amount of solute per unit volume of the solution. Usually, it takes the unit mol/L. The calculation for this problem is as follows:
1.02 mM = (1.02 mol / mL) (2.0 mL) = 2.04 mol
Thus, the solution has 2.04 mol of glucose.
Answer:
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.
Explanation:
The answer is decomposition, ocean release and respiration. hope this helps u :D
