The oxidation number of iodine is 5 in Mg(IO3)2 which can be calculated as
Mg(IO3)2
MgI2O6
As we know that
Mg has +2
O has -2
So,
(+2) + 2I + 6 (-2)=0
2 + 2I - 12 =0
10+ 2I =0
10 = 2I
I =5
At STP one mol weighs 22.4L
Moles of O_2
1 mol.O_2 can create 2mol water
moles of water
Volume of water
To convert take 1.8 * degrees C + 32
1.8 * 35 + 32
63 + 32 = 95 so C
Answer: A. 11.15
Explanation:
The pH of a solution is given by the formular; pH = -log [H+].
pH = - log [ 7.0 x 10 ∧-12]
= 12 - log 7
= 12 - 0.845
= 11.15
