Diborane (B2H6) is widely used in the synrhesis of organic compounds. Diborane itself is made by the reaction 2NaBH4 +I2 -> B2H6 + 2NaI +H2. if 6,3 g of NaBH4 are rected with excess I2 how many grams of diborane could theretically e isolated? if 1.9 g of diborane is actually produced what is the percent yield of the reaction

Me i dont know what to do! 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.
