Bonding atoms that experience large differences in electronegativity values will experience what type of bond? (2 points) select one: a. ionic b. covalent c. hydrogen d. sharing of electrons

Option (a) is the correct answer.

Explanation:

A bond that is formed because of transfer of electrons from one atom to another is known as an ionic bond.

For example, sodium has 1 valence electron and chlorine has 7 valence electrons. So, transfer of one electron from sodium to chlorine will result in an ionic bond leading to the formation of compound NaCl.

Also, there is large difference in electronegativities of a metal and a non-metal. Usually, a metal and a non-metal form an ionic bond.

On the other hand, a bond formed by sharing of electrons is known as a covalent bond.

For example, molecule has covalent bond.

Hence, we can conclude that bonding atoms that experience large differences in electronegativity values will experience ionic bond.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2
