PLEASE PLEASE HELP WILL GIVE BRANLIEST in the reacion, Zn + 2 HCl --> ZnCl2 +H2
25 grams of Zn are reacted with 17.5 grams of HCl. how many grams of the excess reactant is left over?

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

"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."

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
