Because gravity is trying to pull it down not up and when it's going down it's going with gravity not against it.
Answer:
Option (B) It separates the hydrogen ion (H+) from the chlorine ion (Cl–).
Explanation:
The reaction above simply illustrate the dissociation of HCl when dissolve is water.
When HCl is dissolved in H2O, it will separate into the hydrogen ion, H+ and chloride ion Cl- as shown below
HCl —> H+ + Cl-
The water help to separate the H+ from the Cl-
HCl is a monoprotic acid, which means that each mole of HCl releases one mole of hydrogen ions upon dissociation. Therefore, we calculate the moles of HCl present using:
Moles = Molarity * Volume (in liters)
Moles = 11.6 * 0.015
Moles = 0.174 moles of HCl = moles of H+ ions
Now, we use the same formula to calculate the molarity of the new solution, since the number of moles remains constant.
0.174 = M * 0.5
M = 0.348 M
The molarity of the new solution is 0.348
Balanced chemical reaction: 2CH₄(g) ⇄ C₂H₂(g) + 3H₂(g).
1) In a chemical reaction, chemical equilibrium is the state in which both reactants (methane CH₄) and products (ethyne C₂H₂ and hydrogen H₂) are present in concentrations which have no further tendency to change with time.
2) At equilibrium, both the forward and reverse reactions are still occurring.
3) Reaction rates of the forward and backward reactions are equal and there are no changes in the concentrations of the reactants and products.
