the law that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
Omg its a lol no more 2 explain lol That ez shizkubob
Answer:
The answer to the first question is B) left and the answer to the second question is A) right.
Explanation:
To solve these questions, we must remember that if a change is made to the system, the system will work to reduce that change. In these problems, if we add one reactant/product, the system will shift to use this compound and re-establish equilibrium.
For the first question, H2 is a product. If we add H2 to the system, the equilibrium will shift to the left to decrease the concentration of H2. The second question is the opposite since we are adding CH4 (a reactant). When CH4 is added, the system shifts to the right to decrease the concentration of CH4.

Answer:
See attachment for mechanism.
Explanation:
The Fischer esterification reaction is a nucleophilic substitution <u>in the acyl group of a carboxylic acid, catalyzed by an acid.</u>
1) The protonation of the oxygen of the carbonyl group activates the carboxylic acid...
2) ... against a nucleophilic attack by the alcohol, and produces a tetrahedral intermediate.
3) The transference of a proton from an oxygen atom to another produces a second tetrahedral intermediate and converts the -OH into a good leaving group.
4) The loss of a proton and the expulsion of H₂O regenerates the acid catalyzer and gives an ester as a product.
