From this list below, select the items which are properties of ionic compounds. * 5 points low melting point conductors of electricity when in liquid or aqueous state high melting point mostly liquids and gases at room temperature soluble in water

conductors of electricity when in liquid or aqueous state

high melting point

soluble in water

Explanation:

An ionic substance is any substance that is composed of two ions of opposite charge.

In the solid state, ionic substances do not conduct electricity because the ions are trapped inside the crystal. When in liquid state or in aqueous solution, these ions are now free and the solution becomes an electrolyte.

All ionic substances have a very high melting point and dissolve in water easily.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
