less concentraion = less molecules per unite volume , less molecules = less reaction , so less zinc gets used up

ya, but the same amount of product is formed wid either high or low conc. so wont usin less of reactant give you less of product?

yes the sceond C shoudl have a double bond with O and it should also be connected to another O

THE -C0 is a double bond AND SO C00 makes it connected to another 0

get me?

and im talking about the first C mate .. shouldnt it be bonded to only one O as in the diagram i did?
Maybe your talking about the second C which i know has one double bond with an O and another single bond with another O
