The products of self-ionization of water are... OH⁻ and H₃O⁺
Based on the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.
<h3>Which of the bonds listed is the weakest and which is the strongest?</h3>
The strength of a bond is proportional to the amount of energy required to break or form the bond.
A weak bond will require less energy to form than a strong bond.
A weak bond is unstable while a strong bond is stable.
Data provided:
839 kJ/mol C ≡ C
495 kJ/mo O = O
413 kJ/mo C—H
From the data given of the bonds listed below, the weakest bond is C-H and the strongest bond is C ≡ C.
A strong bond is a stable bond.

Answer:
25.0g is the mass of sulfur
Explanation:
The sulfur and the oxygen are 50:50. That means there is 1 mole of S per mole of O.
To solve this question we need to convert the mass of O to moles, as moles of O = Moles of S, we can find the moles of S and its mass:
<em>Moles O = Moles S:</em>
12.5g O * (1mol / 16g) = 0.781 moles
<em>Mass S:</em>
0.781 moles * (32g / mol) =
<h3>25.0g is the mass of sulfur</h3>
Answer:
B. Nuclear fission
Explanation:
Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.
When an acid is dissolved in water, by releasing protons into the solution, it lowers the pH.
What is pH?
The letters pH stand for the potential of hydrogen since pH is essentially a measurement of the number of hydrogen ions (i.e. protons) in a substance. The pH scale was created in 1923 by scientist Peter Lauritz Srensen. (1868-1969).
The pH of a solution is a key marker of its chemical makeup. The pH can have an impact on the biological processes that take place, the behavior of bacteria, and the behavior of chemicals.
