Trigonal pyramidal has 1 lone pairs and 3 bonds so it is D. PH3
Work: You have to calculate amount of valence electrons for each molecule by looking at the group number and skipping the transition metals. Then you make your Lewis dot structure and see which fits the correct shape. Looking up a molecular geometry chart can help.

The amount of KCl that would be formed will be 478.8 grams
<h3>Stoichiometric calculations</h3>From the equation of the reaction, the mole ratio of K to is 2:1.
Mole of 309 g potassium = 309/39 = 7.92 moles
Mole of 228 g Cl2 = 228/71 = 3.21 moles
Thus, potassium is in excess while Cl2 is limiting.
Mole ratio of Cl2 and KCl = 1:2
Equivalent mole of KCl = 3.21 x 2 = 6.42 moles
Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams
