The ratio of carbon atoms to hydrogen atoms to oxygen atoms in a molecule is 1 to 2 to 1. What is its molecular
formula if its molar mass is 200.18 g/mol?

Chemistry

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

the answer is barium and copper bromide

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.
