A 6.00 L vessel is filled with 1.00 mole each of NH₃, N₂, and H₂. Given the following data... with a calculation of the reaction will go in order to reach equilibrium. You must support your choice

Answers

Answer 1
Answer: 4365 that’s what the answer is
Answer 2
Answer:

Final answer:

The reaction will proceed in the forward direction to reach equilibrium.

Explanation:

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.

The atom in a sample of an element must contain nuclei with the same number of?

Answers

Hey there! 

Answer: Protons 

The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well.

The total mass of the protons in an atom of gold-198 is approximately(1) 79 atomic mass units
(2) 119 atomic mass units
(3) 198 atomic mass units
(4) 277 atomic mass units

Answers

Gold has an atomic number of 79
Protons have a relative mass of 1
Gold-198 is a radioactive isotope of gold, which means it has a different number of neutrons, but the same number of protons and electrons
So the answer is (1) 79 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.

After decaying for 48 hours, l/16 of the original mass of a radioisotope sample remains unchanged. What is the half-life of this radioisotope?

Answers


After the first half-life, 1/2 is unchanged. After the 2nd one, 1/4 remains. After the 4th one, 1/16 remains. So you have 4 half-lives in 48 hours, the half-life is thus 12 hours.

As a Ca atom undergoes oxidation to Ca2+, the number of neutrons in its nucleus(1) decreases
(2) increases
(3) remains the same

Answers

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.
Oxidation refers to a change in electrons (In this case, loss of electrons). It has no impact on the number of neutrons, or for that matter on any sub-atomic particles in the nucleus. So the number of neutrons (3) remains the same
