Answer

The correct answer is:

b. dipole-dipole

Explanation:

The IMF molecules are linked by Van der Waals forces, which are permanent but dipole-dipole junctions.

If the interactions are molecules that are permanently polarized (for example, water molecules that attract other water molecules or other polar molecules), they are found as Keesom forces.

Answer:

D) Covalent Bond

Explanation:

London dispersion forces, dipole-dipole forces and hydrogen bonds are secondary weak forces that exist between molecules. For it to be called a molecule, it shows tha the bond present is a covalent bond. The covalent bond arises from the shaing of electrons between the atoms.

A typical example is the hydrogen molecule, H2. Both hydrogen atoms share the two electrons which signifies a covalent bond.

These models show the electron structures of two different nonmetal elements.
Soloha48 [4]

Answer: Option (D) is the correct answer.

Explanation:

Valence shell is the shell present on the outermost core of an atom and electrons present in the valence shell are known as valence electrons.

If an atom has completely filled valence shell then it means the atom is not reactive in nature because it is already stable.

But when an atom has less than eight electrons in its valence shell then it means to attain stability the atom will readily attract electrons towards itself.

As the given element 1 has 8 electrons in its valence shell. Hence, it is not reactive in nature but element 2 has 6 valence electrons. So, in order to attain stability element 2 will readily attract 2 electrons from a donor atom.

Thus, we can conclude that element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

How many moles of oxygen atoms are in one mole of the molecule Ca5(PO4)3OH?​
Ilya [14]

Answer:

13

Explanation:

There are 13 moles O in a mole of Ca5(PO4)3OH because there are 13 oxygen atoms in every molecule of Ca5(PO4)3OH. Convert moles oxygen to number of atoms of oxygen. One mole is 6.022*10^23, so your conversion factor would be 6.022*10^23 atoms O/mol O.

Which is the reason that ionic compounds are brittle? The bonds between the anions and cations are weak and therefore easily bro
bearhunter [10]
Well ionic compounds are brittle because similar charges repel, which causes them to break usually occurring when a force is applied, like a hammer strike.

The piece of metal is magnetic
Alex_Xolod [135]

Answer:

Explanation:

Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.

r-ruslan [8.4K]

Answer:

E. Evaporation to dryness

Explanation:

E. - Evaporation to dryness is the best method for the recovery of solid KNO3 from an aqueous solution of KNO3.

(KNO3 is very soluble, and will violently decompose if overheated.)

Paper chromatography is for separation of different weight molecules in solution.

B. Filtration  won't work on a solution

C.Titration would contaminate the salt with something else and is used  

to determine concentrations

D. Electrolysis would destroy the salt
