Suppose there are two known compounds containing the generic elements X and compound. One sample contains 0.33 g of X and the other contains 0.42 g of X. Identify plausible sets of formulas for these two compounds

What does a particular point on a line of a phase diagram represent? o a. the maximum temperature a substance can exist at without bonds breaking b. the pressure created by the kinetic energy of molecules at a particular temperature c. the melting point or boiling point of a substance at a specific pressure d. the conditions in which temperature and pressure have equal effects on a substance

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion

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