Answer: 0.5 M
Explanation:
Ammonium chloride has a gram formula mass of 53.49 g/mol, so 26.8 grams of ammonium chloride is 26.8/53.49 = 0.501 mol.
So since molarity = (moles of solute)/(liters of solution), the answer is 0.501 / 0.25 = 0.5 M
Answer : The shape of the fluoroform molecule is Tetrahedral.
Explanation :
First we have to calculate the Hybridization of the molecule by formula,
![\text{Number of electrons} = \frac{1}{2}[V+H-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5BV%2BH-C%2BA%5D)
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:
Each giant planet has a core of “ice” and “rock” of about 10 Earth masses. Jupiter, Saturn, and Neptune have major internal heat sources, obtaining as much (or more) energy from their interiors as by radiation from the Sun.
