Which pair of elements is most apt to form a molecular compound with each other?

1 answer:

4 0

The pair of elements which is most apt to form a molecular compound with each other would be sulfur and fluorine. In general, a nonmetal and a gas is most likely to form a molecular compound. Considering two metal molecules, most likely these metal atoms would not form a molecule since they are both positive when in ionic form and tends to donate electrons to another atom. For a situation where you have a nonmetal and a metal atom, it would not still be possible to form a molecular atoms since they are likely to form ionic bonds resulting to an ionic compound.<span />

Cations with (+ ) charges lose electrons in order to obtain an octet (8 valence electrons) when they ionically bond with another ion. We're looking for the ions that loses electrons here. So, from the table:

Al 3+ , S 2- , O 2-, Ag + , Ne ( noble gas, no charge)

Since Al and Ag has (+) charges, they are going to lose electrons to form ionic bonds with other atoms.

Given 7.65 mol AgNO3, determine the number of formula units.

Komok [63]

Answer:

The number of formula units of silver nitrate is $4.61\times 10^{24}$ .

Explanation:

Moles of silver nitrate = n = 7.65 mol

1 mole = $N_A=6.022\times 10^{23}$ atoms/ molecules/ ions

Let the number of formula units of silver nitrate be N.

$N=n\times N_A$

$N=7.65 mol\times 6.022\times 10^{23}=4.61\times 10^{24}$

The number of formula units of silver nitrate is $4.61\times 10^{24}$ .

About bonding

Explanation:

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bond.

What must the melting point of the mold be compared to the temperature at which class get soft and why

stiv31 [10]

The answer is that the mold melting point must be higher then molten glass, otherwise the mold would melt when molten glass is poured into it .

I hope this helps :)
