Exactly 75.00 mL of a 333.3 ppm (w/v) sodium sulfite (MM=126.041 g/mol), solution is treated with 150.0 mL of 3.894x10^-3 M perchloric acid (MM= 100.457 g/mol), which results in the formation of sulfur dioxide (MM=64.064 g/mol), water (MM=18.015 g/mol), and sodium perchlorate (MM=122.438 g/mol). What is the ppm (w/v) of the excess reactant once the reaction is complete?

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

The alkali metals (group 1) consist of lithium (3), sodium (11), potassium (19), rubidium (37), cesium (55), and francium (87). they are soft, metallic solids with low densities and low melting points. based on the data shown in figure 1, how many valence electrons do alkali metals share?
