Answer : The shape of the fluoroform molecule is Tetrahedral.
Explanation :
First we have to calculate the Hybridization of the molecule by formula,
where,
V = Number of valence shell electron in central atom
H = Number of neighboring monovalent atom
C = charge of cation
A = charge of anion
The central atom in this molecule is Carbon, it has 4 electrons in their valence shell.
The neighboring monovalent atoms are one Hydrogen atom and three Fluorine atom.
There is no charge of cation and anion on the given molecule.
V = 4
H = 1 Hydrogen atom + 3 fluorine atom = 4
C = 0
A = 0
By the above hybridization formula, we get
= 4
The number of electron pair = 4
The number of lone pair = 0
The number of electrons is 4, this means that the hybridization is and the geometry of the molecule is Tetrahedral.
The geometry of the molecule is shown below.
Answer:
o
Explanation:
it is not a gas because the particles do not move freely it may be a liquid or a solid partly and mostly liquidized.
Energy released from changing the phase of a
substance from the liquid phase to solid phase can be calculated by using the
latent heat of fusion. The heat of fusion of iron is calculated as follows:
<span>Energy = mL(f)</span>
<span>9840 cal (4184 J / 1 cal) = .200 kg x L(f)</span>
L(f) = 2.06 x10^8 J/kg
The answer is b. the water molecules are more closely packed together in ice than in water <span />
