The reaction will proceed in the forward direction to reach equilibrium.
To determine which reaction will go in order to reach equilibrium, we need to compare the initial number of moles of reactants to the stoichiometric coefficients of the balanced equation. The balanced equation for the reaction between NH₃, N₂, and H₂ is:
NH₃ + N₂ ↔ 2NH₃
Since the initial number of moles of NH₃, N₂, and H₂ are the same (1.00 mole each), the reaction will proceed in the forward direction to reach equilibrium.

(2) 119 atomic mass units
(3) 198 atomic mass units
(4) 277 atomic mass units
The total mass of protons in a gold-198 atom is about 79 atomic mass units. This calculation considers the 79 protons, each with a mass of approximately 1 amu.
The correct answer is option 1.
The total mass of protons in an atom of gold-198 is approximately 79 atomic mass units. This is determined by considering the number of protons in the nucleus, which is 79 for gold-198. Each proton has a mass of approximately 1 atomic mass unit (amu). Therefore, multiplying the number of protons by the mass of one proton yields the total mass of the protons.
In the case of gold-198:
Total mass of protons = Number of protons × Mass of one proton
Total mass of protons = 79 protons × 1 amu/proton
Hence, the total mass of protons in an atom of gold-198 is approximately 79 atomic mass units.
In summary, the calculation involves recognizing that the mass number of an isotope is the sum of protons and neutrons. In this specific case, gold-198 has 79 protons, and the total mass of its protons is around 79 atomic mass units.
Therefore, from the given options the correct one is 1.

(2) increases
(3) remains the same
Answer:
Hence the correct answer is remains the same
Explanation:
As a Ca atom undergoes oxidation to Ca2+,as follows:
Ca --- Ca 2+ + 2e-
In the process of oxidation calcium loss 2 electron only there is no change in the number of protons as well neutrons therefore there is no change in the number of neutrons in its nucleus
Hence the correct answer is remains the same
Oxidation:
Oxidation is a process in which either 1 or all following changes occurs:
1. Gaining of oxygen atoms
2. Loss of electrons
3. Loss of hydrogen atom.
4. Increasing oxidation number.
Reduction:
Reduction is a process in which either 1 or all following changes occurs:
1. Loss of oxygen atoms
2. Gaining of electrons
3. Gaining of hydrogen atom.
4. Decreasing oxidation number.
