Water was bored. He decided to go through the water cycle. He flew in the air as gas, then condensed into water again, and then rolled down into a river, only to find out that he would be stuck doing it forever
. The end
Answer:
a. AlCl is incorrect because Al has a +3 charge while Cl only has a -1 charge. The correct formula would be AlCl₃. This balances the charges.
b. Na₃SO₄ is incorrect because Na has a charge of +1 and there are three of them so its +3 and SO₄ has a charge of -2. The correct formula would be Na₂SO₄. This balances the charges.
c. BaOH₂ is incorrect because the polyatomic ion OH would not be written that way. It would be written like this Ba(OH)₂. Writing it like BaOH₂ gives the impression that instead of having 2 OH it has 2 H and 1 O.
d. Fe₂O is incorrect because Fe either has a +2 charge or +3 charge while O has a -2 charge. Possible correct answers could be FeO (iron (II) oxide) or Fe₂O₃ (iron (III) oxide).
Answer : The balanced reaction in acidic solution is,
Explanation :
The given partial equation is,
First we have to separate into half reaction. The two half reactions are:
Now we have to balance the half reactions in acidic medium, we get:
............(1)
............(2)
Now we have to balance the electrons of the half reactions. When we are multiplying the equation (1) by 2, we get
...........(3)
Now we have to add both the half reactions (2) and (3), we get the final balanced chemical reaction.
