C4H10 + 02 - CO2 + H2O (unbalanced) What mass of CO2 is produced in the complete combustion of 83.6 g of butane, C4H10, to CO2 and H20?

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
