shown below, describe to the reader what they are observing and how an absorbance titration would
allow for a more accurate calculation of the pk, of bromocresol green. Recall that molecules absorb
light, and instruments and humans see transmitted light (color opposites). The expectation is a
paragraph of at least 120 words in complete sentences with all references cited.

answer; /// i do believe that the correct answer is (a) boiling

it should be all of them because it asks if you included all of those in your answer

explanation:

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
