What is the molecular geometry about the antimony atom in the structure below? [Image description: A Sb atom is singly bound to five Fatoms. There is one electron pair on Sb. Each Fhas
three electron pairs. The molecule as a 2- charge.]
720
FF

Square Pyramidal.

Explanation:

Because the Sb atom has six electron domains (five bounded and one unbounded), its electron domain geometry is octahedral.

Because one electron domain is unbounded, its molecular geometry is square pyramidal.

gold is my favorite solid.

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
