What is the approximate pH of a .06 M solution of CH3COOH given that Ka= 1.78*10-5
Step2247 [10]
CH₃COOH ⇔ CH₃COO⁻ + H⁺

[CH₃COO⁻] = [H⁺] = x

K=\frac{|CH_{3}COO^{-}|*|H^{+}|}{|CH_{3}COOH|}=\frac{x^{2}}{|CH_{3}COOH|}\\\\
1,78*10^{-5}=\frac{x^{2}}{0,06} \ \ |*0,06\\\\
0,1068*10^{-5}=x^{2}\\\\
x_{1}\approx0,001 \ \land \ \ x_{2}=\approx-0,001\\\\
pH=-log|H^{+}|=-log0,001=3

The energy produced when nucleons fuse together is called the: Select the correct answer below:
saveliy_v [14]

Answer:

Option C (nuclear binding energy) is the appropriate choice.

Explanation:

  • At either the nuclear scale, the nuclear binding energy seems to be the energy needed to remove and replace a structure of the atom itself into the characterize elements (to counteract the intense nuclear arsenal).
  • Nuclear warheads (bargaining power) bind everything together neutrons as well as protons within an elementary particle.

Some other options in question aren't relevant to the particular instance. So that the option preceding will also be the right one.

If ms2 is 40.06% sulfur by mass, what is the identity of the metal m?
musickatia [10]

Answer:

The mass percent refers to the mass of an element in a compound. It is one of the ways of expressing concentration. The mass percent of the solution provides the percentage of the amount of solute present in grams of solution.

The mass percentage of S=40.06 % and the molar mass of S= 32. By applying the formula of mass percent,we can calculate the molar mass of M.

The molar mass of M=159.76-64=95.76

We know that the element of molybdenum has molar mass of 96. Therefore, the element M is <u>Molybdenum.</u>
