When two nitrogen atoms bond together in N2, what type of covalent bond do they form? A double bond, because they overlap orbitals to share two electrons.
A double bond, because they overlap orbitals to share two pairs of electrons.
A triple bond, because they overlap orbitals to share three electrons.
O A triple bond, because they overlap orbitals to share three pairs of electrons.

A triple bond, because they overlap orbitals to share three pairs of electrons.

Explanation:

hey there,

< Draw out the Lewis diagram. You will notice there are 3 bonds, and a pair of electrons left on each nitrogen. The amount of electrons being shared between them would now be 6. Here is how it would actually look like:

Hope this helped! Feel free to ask anything else.

idk

explanation:

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
