what is the molecular geometry of IO3- when the angle is 105 degree? i think it means that what is MG of IO3- when angle is set to 105 degrees? Im not really sure

can u stop trying to trick people. I got the series which is balmer, but i couldn't find the number for nf

do we have to include the products that it yields, is it CaBr2Li2C2O4

The answer is c without a doubt.
