Answer #1

Solved the first two problems since MCQ type, as per Chegg guidelines ,post one problem per posted question

1) The correct answer is Option d

The molecular bonds will form dipole-dipole interactions, london dispersion and hydrogen bonds

2) The correct answer is Option a

The total amount of solute is irrespective of dilution, since the number of moles of solute will be fixed which is

number of moles of HCl = volume of solution (in L) * molarity = 50/1000 * 0.1 = 0.005 moles
