The total pressure in a closed vessel containing N2, O2 and CO2 is 30 atm. If the partial pressure of N2 is 4 atm, and the partial pressure of Oz is 6 atm, what is the partial pressure of CO2?

the maximum mass of nh3 is nh3 in grams

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.
