Doubling the amounts of both ammonia and ammonium chloride is the action
that will most likely strengthen the buffering capacity of a solution that contains
equal amounts of ammonia and ammonium chloride, and is buffered at a pH of 9.25.
Answer: 12,600,000Cm
Explanation:
From the data's;
Charges(q) = 1.8 PC equal to 1.8 x 10^¹²C
Distance = 7 micrometer, is equal to 0.0000070m
From the equation of electric dipole moment, p= q x d, where q= charge, d=distance and p is the dipole moment.
Then we have 1.8x10^¹² x 0.0000070= 12,600,000Cm
NB: The charges are identical.
When the two spheres touch each other, part of the charge recombine together. The part of charge that recombines is the excess of positive charge on sphere Y,

, that recombines with an equivalent charge of

located on sphere X. As a result, the total charge remained on the two spheres is the excess of negative charge remained on sphere X:

Since the two spheres are identical, they have same capacity, so this charge will now redistribute equally on the two spheres: therefore, at the end, each sphere will have
