The calibration test on an automatic titrator was programmed with a target value of 6.000 mL for a base neutralization. The actual process yielded the following volumes: 5.597 mL, 5.596 mL, 5.598 mL, 5.597mL, 5.599 mL. These measurements can best be described as:

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

14,16 18 reacts with group

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.
