Answer:
Calcium oxide （CaO）is ionic.
Molar mass HCl = 36.5 g/mol
number of moles:
mass of solute / molar mass:
9.63 / 36.5 => 0.263 moles
Volume = 1.5 L
M = n / V
M = 0.263 / 1.5
M = 0.1753 mol/L

The answer is (3) hydrogen ions as the only positive ions in solution. One ionic compound must have positive ion and negative ion at the same time. The Arrhenius base has hydroxyl ion as only negative ions in solution.
The given blanks can be filled with attraction and repulsion.
Gases comprise tiny particles of matter, which are in spontaneous motion. The particles of a gas are colliding continuously with each other and with the container walls. These collisions are considered elastic, that is, no net loss of energy takes place due to collisions. The particles of gases are distinct away from each other by large distances.
There are no interactive forces, that is, repulsion or attraction among the gas particles. The average kinetic energy of gas particles depends upon the temperature of the gas.
