I need help! In an equilibrium reaction with a Keq of 1 × 108 A. products are favored. B. the reaction is nonspontaneous. C. the reaction is endothermic. D. reactants are favored.
Answers
Answer: The correct answer is Option A.
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants. It is represented as
For the general reaction:
Expression for equilibrium constant is given as:
Conditions for are:
, then products are favored
, then forward reaction is equal to backward reaction
, then reactants are favored
As, and is very much greater than 1, so products will be favored.
Hence, the correct answer is Option A.

The addition of a proton to the sulfur atom has resulted in the formation of an isotope. Thus, option A is correct.
The addition of a proton to the nucleus has been resulted in the change in the atomic mass of the element without changing the atomic number.
The atomic mass has been the number of protons and neutrons present in the nucleus. The ions have been resulted when there has been a change in the number of electrons in the atom.
The isotopes have been the element that has been considered of the same atomic number with different atomic masses. The addition of a proton to the sulfur atom changes its atomic mass and thereby forms the isotope of sulfur. Thus, option A is correct.

Answer:
Created a positively charged ion of Sulfur
Explanation:
As the number of protons in Sulfur is more than the electrons in Sulfur, thus it'll be a positively charged ion of Sulfur

The isotope 40Ar contains 18 protons, 18 electrons, and 22 neutrons.
The isotope 40Ar refers to the isotope of argon, which has an atomic number of 18.
Since the atomic number represents the number of protons in an atom, we can conclude that the isotope 40Ar contains 18 protons.
Argon is a neutral atom, so the number of electrons also matches the number of protons. Therefore, the isotope 40Ar contains 18 electrons.
To find the number of neutrons, we need to subtract the atomic number (protons) from the mass number (protons + neutrons). The mass number of 40Ar is 40. Subtracting the atomic number of 18 from the mass number gives us:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 40 - 18
Number of neutrons = 22
Therefore, the isotope 40Ar contains 18 protons, 18 electrons, and 22 neutrons.

Answer:
18 protons, 18 electrons, 22 nuetrons
Explanation:
Argon has an atomic # of 18. Atomic #s show the amount of protons and electrons it has. Atomic mass - atomic # = # of nuetrons. 40-18=22

It is also extremely expensive to process gold to its purest form, so pure gold jewelry would be ridiculously expensive, to the point of no demand.
Hope that helped =)
2. Pure gold isn't durable, and wouldn't last, nor would you be able to keep it on your finger since it's so soft. If you're gonna wear a ring for a life-time, it has to have durability.
