Based on the data table, one scientist concludes that the mass of AgCI formed depends only on the amount of HCI added, and another scientist
concludes that the mass of AgCl formed depends on the amount of the
limiting reactant. How might this conflict be resolved?

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.  

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
