<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
To calculate the hybridization of 
, we use the equation:
![\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pair%7D%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom (S) = 6
N = number of monovalent atoms bonded to central atom = 0
C = charge of cation = 0
A = charge of anion = 0
Putting values in above equation, we get:
![\text{Number of electron pair}=\frac{1}{2}[6]=3](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electron%20pair%7D%3D%5Cfrac%7B1%7D%7B2%7D%5B6%5D%3D3)
The number of electron pair around the central metal atom are 3. This means that the hybridization will be 
and the electronic geometry of the molecule will be trigonal planar.
Hence, the correct answer is Option D.

Answer:
Enamel is there to protect teeth from decay and damage. Every time you eat and drink, you expose your teeth to acids and bacteria from your food. This would seriously harm teeth if it weren't for enamel.

Answer:
320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.
Explanation:
The balanced reaction is:
SO₃ + H₂O → H₂SO₄
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- SO₃: 1 mole
- H₂O: 1 mole
- H₂SO₄: 1 mole
Being the molar mass of each compound:
- SO₃: 80 g/mole
- H₂O: 18 g/mole
- H₂SO₄: 98 g/mole
By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
- SO₃: 1 mole* 80 g/mole= 80 grams
- H₂O: 1 mole* 18 g/mole= 18 grams
- H₂SO₄: 1 mole* 98 g/mole= 98 grams
Then you can apply the following rule of three: if 1 mole of sulfuric acid is produced by the reaction of 80 grams of sulfur trioxide, 4 moles of sulfuric acid is produced from how much mass of sulfur trioxide?
mass of sulfur trioxide= 320 grams
<u><em>320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.</em></u>
