Answer:
Perchloric acid is one of the six common strong acids, which means 100% dissociation in water. Thus, [HClO4] = [H+].
pH = -log 2.65 x 10^-5 = 4.58
Explanation:
I am new, and I am giving this a try. Hope this helps : )
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:
Yes, it's a mixture as more than 1 type of molecules are present!!
Answer:
The pure crystals were soluble in the wash solvent.
Explanation:
The pure crystals on the funnel dissolved because they were soluble in the solvent used for washing. They were carried into the filter flask by the solvent.
Answer:
C
Explanation:
The higher the period the higher the activity of an element, therefore, since iodine is in period 6 and bromine is in period 5, the described reaction is not possible due to the fact that bromine is less active
