Answer:
12 valence electrons
Explanation:
Number of valence electrons: 2 carbons (2 x 4 valence electrons= 8e-) and 4 hydrogens (4 x 1 valence electron = 4 e-) added up gives us 12 valence electrons to work with: Counting the bonds we have made shows that we have used up 10 of the 12 valence electrons leaving us with 2 to complete the octets.

Answer:
0.0957 M
Explanation:
Equivalence appears to occur upon addition of 20 mls of 0.0957 M HCl.
0.02 L x 0.0957 mole/L = 0.001914 moles HCl added
CH3NH3 + HCl ==> CH3NH4^+ Cl^-
Molarity of CH3NH3 initially present = 0.0957 M
pH < 7 because the reaction is between a strong acid (HCl) and a weak base (methylamine)
