In a certain chemical reaction compound combines with compound to produce compound (and no other products). measurements were taken of the amounts of and present before and after a reaction that produced some : compound initial amount final amount calculate the theoretical yield of . round your answer to the nearest . suppose the percent yield of in this reaction was . calculate the actual amount of that was isolated at the end of the reaction. round your answer to the nearest .

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
