the known density of the liquid is
the density of a liquid
Thus, experimental error of 0.0108 g /mL is present.
Thus, Percentage error of 7.31 % is present.
Answer:
a) octahedral electron domain geometry
b)square planar molecular geometry
c) a bond angle of 90°
Explanation:
According to the Valence Shell Electron Pair repulsion Theory, the shape of a molecule is dependent on the number of electron pairs on the valence shell of the central atom in the molecule. These electron pairs orient themselves as far apart in space as possible to minimize electron pair repulsion.
Electron pairs may be lone pairs or bond pairs. Lone pairs of electrons cause more repulsion than bond pairs. These lone pairs often cause the molecular geometry to depart from what is predicted on the basis of the electron domain geometry due to greater repulsion of lone pairs.
When a molecule has six electron domains consisting of four bond pairs and two lone pairs, the bonding pairs arrange themselves at the corners of a square at a bond angle of 90° with the lone pairs found above and below the plane of the bonding groups leading to a square planar molecular geometry
Ionization is a process which refers to the release of electron ( and not attraction) from an atom.
Resonance refers to the movement of electron or delocalization of electrons within the molecule
Hybridization refers to the mixing of orbitals to form new orbitals that explain the geometry of a molecule
Electronegativity is a measure of the tendency of an atom to attract electrons towards itself.
Ans D) electronegativity
It helps frame the idea that citizen ship requires being actively involved in civic life.
<h2>Answer:</h2>
The last statement is true. which is:
Mg is less reactive than Na because Mg has to lose one more electron than Na to complete its outermost shell.
<h3>Explanation:</h3>
Mg belongs to group II and Na belongs to group I.
Group II elements are less reactive than Group I elements. This is because it is more difficult to lose two electrons compared to losing just one electron.
