PLEASE ANSWER ASAP For the reaction SO3 + H2O --> H2SO4, calculate the Percent Yield if 500. g of Sulfur
Trioxide (SO3)reacts with excess water to produce 554 g of Sulfuric Acid (H2SO4).

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

the maximum mass of nh3 is nh3 in grams
