Consider the following reaction:
2co (g) + o2 (g) > 2co2 (g)

imagine that this reaction occurs in a container that has a pistonthat moves to allow a constant pressure to be maintained when thereaction occurs at constant temperature.
(1) what happens to the volume of the container as a result of thereaction. explain.
(2) if the piston is not allowed to move, what happens to thepresure as a result of the reaction?

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

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.
