Answer:
The electron pair geometry is Trigonal planar
Molecular geometry - Bent
Approximate bond angle - <120°
Explanation:
The valence shell electron pair repulsion theory enables us to predict the shapes of molecules based on the number of electron pairs present on the valence shell of the central atom and based on the hybridization state of the central atom.
sp2 hybridization corresponds to trigonal planar geometry. Let us recall that the presence of lone pairs causes a deviation of the molecular geometry from the expected geometry based on the number of electron pairs.
Hence, owing to one lone pair present, the observed molecular geometry is bent.
Answer:
5.81 g/L
Explanation:
Let's apply the Ideal Gases Law to determine this:
P . V = n . R . T
Pressure = 1.6 atm
Volume = ?
Mol = 1 mol
Temperature = 96 K
In order to find the density, we should know the volume of the atmosphere which is a mixture of gases so, we consider all the atmosphere as a unique ideal gas.
1. 6 atm . V = 1 mol . 0.082 L.atm/mol.K . 96K
V = (1 mol . 0.082 L.atm/mol.K . 96K) / 1.6 atm
V = 4.92 L → As this is the volume for the whole atmosphere and the mass of 1 mol is 28.6 g, density should be:
28.6 g / 4.92L = 5.81 g/L
Density → mass / volume
The conductivity would decrease because the concentration of ions decreases.
As barium hydroxide, a solution is added to sulphuric acid, the Barium ions replace the hydrogen ions to form a precipitate. An insoluble solid doesn't contribute ions and as such the forming of the solid barium hydroxide would mean a decrease in the concentration of the ions.
Answer:
403 grams
Explanation:
7.21 mol. Fe x (55.86 g Fe / 1 mol. Fe)
=403 grams Fe
