A. The box will move to the right
It alwase equals the same amount of mass after the reaction
The balanced chemical equation representing the reaction of ammonia with hypobromite is:
The mass of =1.69mg
Moles of =
Calculating the moles hypobromite that would react with :
Volume of hypobromite required for titration = 1.00 mL
Molarity of hypobromite solution =
