Pretend that you are the size of an atom, observing a reaction between a potassium atom and a fluorine atom. write an account of the formation of an ionic bond as the atoms react. tell what happens to the valence electrons on each atom and how each atom is changed by losing or gaining electrons.

How would you reduce the volume of gas

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
