Answer:
Explanation:
I can do it, but it may not be right. The atoms/ions and charges are all balanced, but I'm just not sure.
12Br2 + 12H20 ==> 4BrO3^- +20Br- + 24H+ You can divide this by 4
3Br2 + 3H20 ==> BrO3^- + 5Br^- + 6H+
Element/ion Left Right
Br 3*2 = 6 1 + 5 = 6
H 6 6H+
O 3 3
Charges 0 -1 - 5 + 6 = 0
The H+ represents an Acid. The problem is it says that the reaction takes place in an acid. It is so long ago, I don't remember if this includes being on the right.
Anyway it is balanced.
Answer:
The concentration of chloride ion is 
Explanation:
We know that 1 ppm is equal to 1 mg/L.
So, the
content 100 ppm suggests the presence of 100 mg of
in 1 L of solution.
The molar mass of
is equal to the molar mass of Cl atom as the mass of the excess electron in
is negligible as compared to the mass of Cl atom.
So, the molar mass of
is 35.453 g/mol.
Number of moles = (Mass)/(Molar mass)
Hence, the number of moles (N) of
present in 100 mg (0.100 g) of
is calculated as shown below:

So, there is
of
present in 1 L of solution.
