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 : )
The correct answer would be D. Ca^2+ has 18 electrons. This is because 2+ means that 2 electrons have been removed, and Ca starts out with 20 electrons. As 20 - 2 = 18 electrons, D is the correct answer.
Hope this helps!
H2O, one Oxygen in the middle, surrounded by 2 hydrogen, usually close to each-other, which gives it polarity
The given word equation is:
Nitrogen trifluoride-->Nitrogen + Fluorine
The chemical formula of nitrogen trifluoride is 
and that of nitrogen gas is 
and fluorine gas is 
.
The balanced chemical equation representing the decomposition reaction of nitrogen trifluoride to nitrogen and fluorine will be,
The chemical formula of fluorine gas will be as fluorine exists as a diatomic gas in it's pure state. The coefficient of fluorine will be 3
Therefore, the correct answer is a) 3F2
