What is the oxidation number for iodine in Mg(IO3)2 ?

navik [9.2K]

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

How many moles of atoms are in 7.00 g of 13c? express your answer numerically in moles?

Nadusha1986 [10]

Molar mass of 13c = 13 grams
number of moles = mass / molar mass
therefore,
number of moles = 7 / 13
To know the number of atoms in 7/13 moles, we simply multiply the number of moles by Avogadro's number as follows:
number of atoms = (7/13) x 6.022 x 10^23 = 3.2426 x 10^23 atoms

Select the electron-domain geometry for a molecule with three bonding domains and one nonbonding domain.

mamaluj [8]

Answer: C) Tetrahedral

Explanation:

The number of electron pairs is 4 that means the hybridization will be $sp^3$ but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.

Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be $sp^2$ .

Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be $sp^3$ .

Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be $sp^3d$ .

Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be $sp^3d^2$ .
