A father and his young son walk by a store and see a big sign in the store window advertising a "Fire Sale" next Tuesday. Although the father knows this means that the store will be selling their goods at greatly reduced prices, his son wonders why anyone would sell "fire." This difference in their reactions is due to:

semantics

Explanation:

Semantics is the study of the connection among words and how we draw significance from those words. Individuals can completely decipher words diversely and draw various implications from them.

Semantics implies the significance and translation of words, signs, and sentence structure. Semantics to a great extent decide our understanding cognizance, how we get others, and even what choices we make because of our translations. Semantics can likewise allude to the part of study inside phonetics that manages language and how we get meaning. This has been an especially intriguing field for philosophers as they banter the quintessence of importance, how we construct meaning, how we share significance with others, and how significance changes after some time.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
