The total number of boron-oxygen bonds in borax is ′x′′x′ and boron-oxygen-boron bonds are ′y′′y′. Then the value of x−yx - y is:The total number of boron-oxygen bonds in borax is ′x′ and boron-oxygen-boron bonds are ′y′ . Then the value of x - y

Correct answer

9

Step-by-step solution

B−OB - O bonds =14= 14

B−O−BB - O - B bonds =5= 5

∴x−y=14−5=9∴ x - y = 14 - 5 = 9

The total number of boron-oxygen bonds in borax is ′x′ and boron-oxygen-boron bonds are ′y′ . Then the value of x - y
