Answer:
B.) More NO would form.
Explanation:
If the amount of N₂ increases, the equilibrium will be out of balance. In order to restore the balance, the reaction will shift to the products side. As such, the amount of NO will increase.
According to Le-chatlier principle, if N₂ is added to the reaction system, then more NO will be produced so as to decrease the amount of N₂.
What is Le-Chatlier principle ?The Le Chatlier's Principle, also known as the Le Chatlier's Law, is a principle in chemistry that states that when a system at equilibrium is subjected to a change in conditions, such as temperature, pressure, or concentration, the system will adjust its equilibrium position to counteract the change and restore equilibrium.
In other words, if a system is disturbed from its equilibrium state, it will try to minimize the effect of the disturbance by shifting the equilibrium position in a direction that partially offsets the disturbance.
If any substance is added to the system, the equilibrium will shift to the direction in which the added substance is consumed. Hence, as N₂ is added to the system, it will consumed to give the product NO.

Which atom absorbs more energy- one in which an electron moves from the the second shell to the third shell, or an atom which an electron moves from the first to the third shell?
An atom which an electron moves from the first to the third shell atom absorbs more energy.
An atoms may occupy different energy states . The energy states are discrete , that means they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.
The lowest possible energy levels that the atom can occupy is called ground state.The energy levels which is higher to the ground state is called excited state.
The more energy absorb when electron move from first to third because in this second energy level have to pass to reach at third energy level.

The pH of a 0.250m solution of succinic acid is 2.42.
What is succinic acid?Succinic acid is one of the naturally occurring dicarboxylic acid having four carbon, which is produced by LPG.
It can be used in many chemical, food, and pharmaceutical industries.
Given,
pKa = 4.21
As we know that,
pKa = - logKa
4.21 = -logKa
Ka = antilog(-4.21)
Ka = 6.1 × 10^(-5)
Now, let the concentration of [H+] = [A-] = x
Ka = [H+] [A-] /[HA]
6.1 × 10^(-5) = x^2/ (0.25-x)
x^2 = 1.52 × 10^(-5)
x = 3.89 × 10^(-3)
Thus, the concentration of [H+] = [A-] = 3.89 × 10^(-3).

Definition of surface area -
To recall, the surface area of an object is the total area of the outside surfaces of the three-dimensional object i.e, the total sum of the area of the faces of the object. It is measured in terms of square units. The amount of area covered by the surface of something. The lake has roughly the same surface area as 10 football fields.The surface area is calculated as -
Conversion of units -
[tex]26 m * \frac{100 cm}{1 m} = 2600 cm[/tex]
[tex]279 kg * \frac{1g}{1000 kg} = 0.279 g[/tex]
[tex]0.0015 mm * \frac{0.1 cm}{1mm} = 0.00015 cm[/tex]
Now we use formula for volume -
[tex]Volume = \frac{mass}{density}[/tex]
[tex]= \frac{0.279 g}{19.3 g/ cm^{3} }[/tex]
= 0.014559 g/cm³

Sample Response: The change in her position (from beginning to end), along with the direction, is considered her displacement. This value is a measurement and a direction. The total distance along the path from her starting point to her end point is considered her distance. This value is a measurement only. What did you include in your response? Check all that apply.
The sample response given in the question is right. Displacement is the shortest distance between the initial and final points of a body. Distance is the length of actual path of the body between initial and final positions.
To find the answer, we need to know more about the distance and displacement.
How distance differ from displacement?Displacement is the shortest distance between the initial and final points of a body.It is the change in position with a fixed direction.Displacement is a vector quantity and can be positive, negative or zero values.Distance is the length of actual path of the body between initial and final positions.It's a scalar quantity and it can be positive or zero.The magnitude of displacement is less than or equal to the distance travelled.Thus, we can conclude that the given sample response is right.
