Answer: to find a cure for the common cold to produce insulin for diabetics
Explanation: It has helped many people
Answer:
see explanation
Explanation:
Given PH₃
Valence = P + 3H = 1(5) + 3(1) = 8 valence electrons
Bonded Substrates = 3H = 3(2) = 6 bonded electrons
Nonbonded Pairs = (V - S)/2 = 8 - 6 / 2 = 2/2 = 1 Nonbonded pair (or 1 free pr)
Lewis Structure => 3 Bonded Pr + 1 Nonbonded Pr => :N-(H)₃ => Pyrimidal Geometry. (See images below).
