QUESTION 51 Buffer capacity is best defined as: OA) Buffer capacity is the amount of acid or base that can be added to a buffer
Schach [20]

Answer:

The best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"

Explanation:

A buffer is a solution that is somewhat resist to pH changes by reacting with acids and bases that may be added into the solution. It's capacity is the amounto of acid or base that can be added into solution without much change in pH.

So the best definition is: "Buffer capacity is the amount of acid or base that can be added to a buffer without destroying its effectiveness"

What does conserving mass mean in a chemical equation?
lubasha [3.4K]
The law of conservation of mass states that mass or matter cannot be created or destroyed, only transferred or recombined.
For chemical equations, this law means that each element must be accounted for equally both for reactants and products. So the same numbers of each atom must match on each side, hence the necessity for balancing the chemical equation accurately. This created a field of chemistry called Stoichiometry, which accounts for the conservation of matter throughout chemical reactions and processes.

How would you build a model that is ionized? what happens if an atom is too ionized? how would you build a model that is radioac
tatyana61 [14]
It will probably zip far from you and join itself to an adjacent molecule or atom. it gets to be distinctly radioactive when its core contains an excessive number of or an excessively couple of neutrons. Attempt to keep an indistinguishable number of neutrons and protons from you construct your iota. In the event that the awkwardness is excessively extraordinary, radioactive rot will happen.
