Definitely not! Gases such as HCl that ionize in water are far more soluble than noble gases.
no all the salts have different solubility depending upon their extent of ionization
gravity separated them by density, iron in the center water and gasses on the outside.
The atoms are the same in all 3.
Yes, water vapor is a gas and all gasses can be compressed.
No, not all nitrate-containing compounds have low solubility in water. Some nitrate salts, such as potassium nitrate and sodium nitrate, are highly soluble in water. However, some metal nitrates, like lead(II) nitrate and silver nitrate, have low solubility in water.
A strong relation is between the solubility and the temperature for all substances. For sodium chloride, at the room temperature, the solubility in water is approx. 36 g NaCl/100 g water.
Air is dissolved in water; all gases have some solubility in liquids.
Not necessarily, depends which group it is and if all are in the same conditions.
All animals breathe out the same gases. It's a fact of Respiration.
No, not all solutes dissolve to the same extent in the same solvent due to differences in polarity, intermolecular forces, and solubility principles. For example, polar solutes tend to dissolve well in polar solvents (like salt in water), while nonpolar solutes dissolve better in nonpolar solvents (like oil in hexane). The "like dissolves like" principle explains this behavior, as the interactions between solute and solvent molecules dictate solubility. Experimentation and solubility data provide empirical evidence for these differences.
All gasses take more place than the same mass of its fluid or steady fase. Here: vapour is not a gas, it is consisted of very small fluid parts!
Yes, the solubility is higher increasing the temperature; but not all vitamins are soluble in water.
