Calculate the theoretical yield and the percent yield of Na2CO3 starting with the grams of NaHCO3 used from the video/data. (mass of empty crucible=33.4g, mass of crucible + NaHCO3=34.47g, amount used of NaHCO3= 3.2g)?

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.  

the answer is option a.
