To what volume should 5.0 g of KCl be diluted in order to prepare a 0.15 M solution? L
Nesterboy [21]

Answer:0.45L

Explanation:

molarity=0.15M

Mass=5g

No of moles=mass ➗ molecular mass

Molecular mass of KCL=39.0983x1+35.453x1

Molecular mass of KCL=74.5513

No of moles=5 ➗ 74.5513

No of moles=0.067

Volume in liters=No of moles ➗ molarity

Volume in liters=0.067 ➗ 0.15

Volume in liters=0.45L

Are all single bonds sigma bonds?
Nikolay [14]
Single bonds are those that bond with one atom, and sigma bonds are the strongest type of covalent bonds that are single bonded. 

That means NO, not all single bonds are sigma bond, but all sigma bonds are single bonds.

Which statement is true? 1. The electronegativity of an atom depends only on the value of the ionization energy of the atom. 2.
lisov135 [29]

Answer:

5. Atoms with high ionization energies and high electron affinities have low electronegativities.

Explanation:

Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.

Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.

Electronegativity is the tendency of an atom in a bond pair to attract the shared pair of electron towards itself.

Low ionization energies as well as low electron affinities mean the atom has low effective nuclear charge, which results in the less attraction of the valence electrons by the atom and thus, low electronegativity.
