An acid dissociation constant, Ka<span>, (also known as acidity </span>constant<span>, or </span>acid<span>-ionization </span>constant<span>) is a quantitative measure of the strength of an </span>acid<span> in solution. It is the equilibrium </span>constant<span> for a chemical reaction known as </span>dissociation<span> in the context of </span>acid<span>–base reactions.

Answer and Explanation:
<em>Metallic bonding occurs between two or the same metals. In a metallic bonding structure, there is an electrostatic attraction between the positive metal ions leaving a sea of delocalised electrons. The sea of delocalised electrons allows metals to conduct electricity because the delocalised electrons are free to carry charge around the structure.</em>
<em>Pure metals are soft because there are layers of metal ions free to slide over each other as they are in a regular arrangement, pattern and size. </em>
<em>Alloys can be harder than pure metals because the different sizes of the atoms disturb the layers, stopping them from sliding over each other. Alloying a pure metal can let the metal become stronger and less reactive.</em>

Answer:
1, 2, 3 and 4.
Explanation:
Hello,
Standard enthalpy of reaction is defined by the difference between the products whole enthalpy and the reagents whole enthalpy. It is known that an element's (by itself or as a diatomic gas) enthalpy of formation is 0, turning out into an equality between the enthalpy of formation and the products whole enthapy. Thus, the reactions that accomplish the given questions are 1, 2, 3 and 4, since the reagents are just the elements sodium, chlorine, carbon and oxygen.
Best regards.
