Select ALL the statement(s) that is/are TRUE about ionic compounds. a. In general, ionic compounds have higher boiling points than molecular compounds.
b. In general, ionic compounds can dissociate and form ions in water.
c. NaCl(s) is an ionic compound and it is poor in conducting electricity when it is in solid state.
d. The overall charge of an ionic compound has to be zero. In general, ionic compounds have poor solubility in water.

a, b and c

Explanation:

A - Ionic compounds have ionic bonds which are far more stronger than the intermolecular forces in molecular (covalent) compounds, so more energy is required to break the bonds, this having a higher boiling point

B - when ionic compounds are placed in water, they are attracted to water due to its dipole nature, so the water molecules attract the positive and negative ions from the compound, breaking the ions apart in a process called dissociation

C - NaCl is an ionic compound as it consists of a metal (Na) and a non-metal (Cl) where Na loses an electron to form +1 ion and Cl gains that electron to form -1 ion. It is poor in conducting electricity when it is in the solid state as the ions are held in fixed positions and cannot move. They can only conduct electricity when molten or dissolved in solution as the ions are free to move around.

D - The first part of the sentence is right : The overall charge of an ionic compound has to be zero as the positive and negative ions are equal, which maintains its neutrality. In general, most compounds have good solubilty in water as water molecules are polar they can attract the positive and negative ions and break up the structure.

There are a few exceptions, for example ionic compounds that have highly polarising ions (are small and have a high charge) which water is unable to break apart the ions.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
