Answer : The molecular geometry of is trigonal pyramidal.
Explanation :
Formula used :
where,
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
The given molecule is,
Number of bond pair = 3
Number of lone pair = 1
The total number of electron pair are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.
But as there are 3 atoms around the central oxygen atom, the fourth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal.
Hence, the molecular geometry of is trigonal pyramidal.
Answer:
C
Explanation:
The answer is shape.
Basically, quantities can either be fundamental or derived. While fundamental are the basic quantities, derived are obtained from combining fundamentals.
To get a shape, we would need the combination of lengths. This makes the shape a derived quantity
The chemical formula is OH-
Answer:
0.11 M.
Explanation:
Hello!
In this case, since the molarity is computed as the moles of solute divided by the volume of solution in L, we first need to compute the moles of potassium in 99.7 mg as shown below:
Moreover, given the density of the seawater (mixture containing the K and other solutes), we can compute the liters as shown below:
Therefore, the molarity turns out:
