Answer:
1.The reaction that opposes the change
Explanation:
Consider the reaction;
A + B ⇄ C + D
If a constraint such as a change in temperature, pressure or volume is imposed on this chemical system in dynamic equilibrium, the equilibrium position will shift so as to annul the constraint.
This shift in the equilibrium position will favour either the forward or reverse reaction depending on the type of constraint imposed on the system.
Hence, If a chemical system is at equilibrium, any change in the system will always result in an increase of the reaction that opposes the change.
Answer:
Explanation:
Hello,
In this case, given the acid, we can suppose a simple dissociation as:
Which occurs in aqueous phase, therefore, the law of mass action is written by:
That in terms of the change due to the reaction's extent we can write:
But we prefer to compute the Kb due to its exceptional weakness:
Next, the acid dissociation in the presence of the base we have:
Whose solution is which equals the concentration of hydroxyl in the solution, thus we compute the pOH:
Finally, since the maximum scale is 14, we can compute the pH by knowing the pOH:

Answer:
B
Explanation:
The blubber is so thick acts as installation
The answer to your question would be is silver(Ag) because gold and silver are highly malleable.
Hope this helped :)
