If 0.25 mol of Br2 and 0.55mol of Cl2 are introduced into a 3.0-L container at 400 K, what will be the equilibrium concentration of BrCl ?? Br2(g)+Cl2(g) 2BrCl at 400 K, Kc= 7.0
Answers
Answer:
[BrCl] = 0,13M
Explanation:
For the reaction:
Br₂(g) + Cl₂(g) ⇄ 2BrCl
kc = [BrCl]²/[Br₂] [Cl₂] (1)
If initial [Br₂] and [Cl₂] are 0,25mol/3,0L=0,083M and 0,55mol/3,0L=0,18M, the concentrations in equilibrium are:
[Br₂] = 0,083M - x
[Cl₂] = 0,18M - x
[BrCl] = 2x
Replacing in (1)
7 = (2x)²/ (0,083 - x)(0,18 - x)
7 = 4x²/ x²- 0,263x + 0,01494
7x² - 1,841x + 0,10458 = 4x²
3x² - 1,841x + 0,10458 = 0
Solving for x:
x = 0,0633. As [BrCl] = 2x. [BrCl] = 0,13M
I hope it helps!

Answer: Acid rain is caused by a chemical reaction that begins when compounds such as sulphur dioxide and oxides of nitrogen are released into the air. These substances can rise very high up into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants called acid rain.

For number two, the equation is balanced. Na in the reactant side has one atom and also in the product side. O has only one atom in the product and in the reactant. There are 2H’s in the reactant and in the product side (present in H2O, the 2 in H stands for 2 atoms of H). One atom of Cl is present in the reactant and product side.
For number three, the reactants are NaOH-sodium hydroxide and HCl-hydrogen chloride(hydrochloric acid). The products are NaCl-sodium chloride and H2O-water.

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light. ... So, Maxwell's equations do say that light is a wave.
