Δngas = 0 - (2 +1)
= -3
<h3>
What is Δngas?</h3>
The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.
Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.
<h3>
Definition of equilibrium</h3>
When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.

Answer: Rate of reaction is an "extensive property". Rate of generation of a chemical species is an "intensive property"
Explanation:
- Let´s check out the Factors that affect the speed of reactions:
Temperature, Physical state of the reagents, Presence of a catalyst, Pressure, light, Concentration of the reagents.
When having a general chemical reaction like this:
aA + bB → cC + dD
Usually the rate of reaction is represented by the next equation
![Rate = k [A]^{x} [B]^{y}](https://tex.z-dn.net/?f=Rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D)
Where k= constant
x, y = reactant orders
A, B = reactant concentration
As we can see in the last equation, the rate of reaction <u>depends directly of the amount of material present</u> in a sample, that is why it is an "extensive property"
- The rate of generation of a chemical species, depends of other factors like Temperature, Presence of a catalyst, Pressure. As we can see all the factors that allow the speed of generation of a new chemical species let us know that this is an<u> </u><u>intensive property</u><u> because it doesn´t depends of the amount of material.</u>

babe I wish I knew I would tell you
Answer:
150.08 g
Explanation:
According the law of conservation of mass, mass can neither be created nor destroyed but is converted from one form to another.
As a result of this, the total mass of reactants must be equal to the total mass of products.
If this is so, we have been told that the mass of AgCl is 150.15 g, the total mass of products is 300.23g.
Therefore; mass of NaNO3 = 300.23 g - 150.15 g = 150.08 g
Answer:
Total pressure = 22.15 atm
Explanation:
Given data:
Total pressure = ?
Volume of container = 7.85 L
Number of moles of N₂ = 4.45 mol
Number of moles of O₂ = 2.45 mol
Temperature = 307 K
Solution:
Pressure of N₂:
PV = nRT
P = nRT/V
P = 4.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 112.16 atm.L/7.85 L
P = 14.28 atm
Pressure of O₂:
PV = nRT
P = nRT/V
P = 2.45 mol ×0.0821 atm.L/mol.K ×307K / 7.85L
P = 61.75 atm.L/7.85 L
P = 7.87 atm
Total pressure = P(N₂) + P(O₂)
Total pressure = P( 14.28 atm) + P( 7.87 atm)
Total pressure = 22.15 atm
