What is the Lewis dot diagram structure for PI2F
1 answer:
Answer:
Please find attached the completed Lewis dot diagram structure for PI₂F
Explanation:
The number of valence electrons are;
Phosphorus = 5 Electrons
Iodine = 2 × 7 electrons = 14 electrons
Chlorine = 7 electrons
The total number of valence electrons = 14 + 7 + 5 = 26 electrons
2) We draw the symbol that represents the basic (general) structure of the molecule as follows;
The sheared electron pair are represented by single bond lines
3) We complete the octet structures round the fluorine and the iodine atoms as attached showing 18 electrons plus 6 shared electron pairs, with a maximum from step 2 to give a total of (18 + 6) 24 electron pairs
4) We add the 2 unaccounted valence electron on the phosphorus atom to give it the stable octet structure, which gives the completed Lewis structure

Answer:
0.020 moles of can be formed
Explanation:
1. First determine the number of moles of LiOH.
Molarity is given by the following expression:
Solving for moles of solute:
moles of solute = M * Liters of solution
Converting 175.0mL to L:
Replacing values:
moles of solute = 0.227M*0.175L
moles of solute = 0.040
Therefore there are 0.040 moles of LiOH
2. Then write the balanced chemical reaction and use the stoichiometry of the reaction to calculate the number of moles of produced:
As the problem says that there are excess of , the limiting reagent is the LiOH.
