Answer:

The correct option is Methylene chloride

Explanation:

Methylene chloride or Dichloromethane has an organic formula of CH2CL2. it is commonly used as solvent, it is very volatile and dissolves many organic compounds including a mixture containing benzoic acid, 2,4-dinitrobenzoic acid, and 2,4,6-trinitrobenzoic acid. It is colorless, has a chloroform like odor and Miscible in ethyl acetate, alcohol, hexanes, benzene, CCl4, diethyl ether, CHCl3.

2. For the reaction, 2SO2(g) + O2(g) 2SO3(g), at 450.0 K the equilibrium con¬stant, Kc, has a value of 4.62. A system was charge
miv72 [106K]

Answer:

Q >> Kc

We have more products than reactans. To reach the equilibrium, the balance will shift to the left.

Explanation:

Step 1: Data given

Temperature = 450.0 K

Kc = 4.62

When Kc > Q, we have more reactants than products. To reach the equilibrium, the balance will shift to the right

When Kc < Q, we have more products than reactans. To reach the equilibrium, the balance will shift to the left.

When Kc = Q,the equiation isatequilibrium

[SO3] = 0.254 M

[O2] = 0.00855 M

[SO2] = 0.500 M

Step 2: The balanced equation

2SO2(g) + O2(g) ⇄ 2SO3(g)

Step 3: Calculate the Q

Q = [SO3]² / [O2][SO2]²

Q = 0.254²/ (0.500 * 0.00855²)

Q = 1765

Q >> Kc

We have more products than reactans. To reach the equilibrium, the balance will shift to the left.

 What is the subject chemistry actually all about? Is it hard, and should I take regular or honors?
horsena [70]
It depends if you are taking the class in high school or college. For college doing the experiments is fun but the calculations is not. Also if you are taking it, bring friends.
