The answer is
a symmetrical molecule.
The accepted model of an atom was made by Schrodinger, which is known as the quantum mechanical model. Unlike Bohr's model, electrons are represented as a cloud and not small balls orbiting the nucleus. There is no define path of electrons in Schrodinger's model, but it can predict the odds of where an electron is located.
The answer to your question is then Electrons form a cloud around the nucleus.
When a weak acid is titrated against a strong base, the pH of the solution rises, levels off through the buffer zone, and then rises quickly to reach the equivalence point.
<h3>What is titration?</h3>
Titration is a typical research center technique for quantitative investigation synthetic to decide the convergence of a recognized analyte. Titration is a crucial cycle in the creation of cheddar. For this situation, titration is significant while estimating the pH and acridity of the underlying milk being utilized to make the cheddar. Corrosive base titration is a quantitative investigation of convergence of an obscure corrosive or base arrangement. Titration, otherwise called titrimetry, is a typical lab strategy for quantitative substance investigation that is utilized to decide the convergence of a distinguished analyte. A reagent, called the titrant or titrator is ready as a standard arrangement. A known fixation and volume of titrant responds with an answer of analyte or titrand to decide focus. The volume of titrant responded is called titration volume.

Answer:
Explanation:
-An endothermic reaction is a chemical reaction that gains or absorbs heat from its surrounding in the form of heat.
-During the reaction, the temperature of the surrounding reduces.
-From the reactions given:
is the only endothermic reaction.
