Answer:
Importance of Phlogiston Theory . Although the theory has since been discarded, it's important because it shows the transition between alchemists believing in the traditional elements of earth, air, fire, and water, and true chemists, who conducted experimentation that led to the identification of true chemical elements and their reactions.
Explanation:
C.Ions with greater charge are more soluble in water.
Explanation:
Compounds with small ions tend to be less soluble than those with large ions.
The solubility of a compound is the result of a competition. The ions in the compound attract each other, and the water molecules attract the ions.
If the water molecules have a greater attraction to the ions than ions have for each other, then the compound will be soluble in water.
Compounds with small ions are less soluble than compounds with large ions. Small ions are closer to each other, so they have strong attractive forces. It is more difficult for the water to break them apart, so they are less soluble.
