A buffer solution is made that is 0.400 M in and 0.400 M in . If for is , what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.092 mol is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter.)

am i too late?

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.
