Predict the geometry around the central atom in so2- a) trigonal pyramidal b) tetrahedral c) octahedral d) trigonal planar e) trigonal bipyramidal

The correct answer is Option D.

Explanation:

To calculate the hybridization of , we use the equation:

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:

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.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
