What is the formula for zinc borate?

Answer 1

i assume its Zn (II)

if it is then the formula is:

ZnBr2

Valency of Zinc is 2

Valency of Bromine 1

swap over and you get one zinc atom and 2 bromine atoms, as zinc needs to gain 2 electrons to have a stable electron arrangement and Br needs one.

Answer 2

Zinc (II) indicates that the zinc has a +2 charge: Zn2+ Bromide always has a -1 charge (that is how many electrons it can add before having to start placing them in a new shell): Br- To form a compound that has a neutral charge, you need to bromides to cancel out the +2 charge of the zinc: ZnBr2

Answer 3

4Zn0 * 6B2O3 * 7H2O

Answer 4

ZnBr2

Answer 5

Zn(HSO4)2

Answer 6

Zn(BrO3)2

Answer 7

ZnBrO3
