When preparing a sodium chloride (NaCl) solution in water, a student notices that by adding 300g of NaCl to 1 liter of water at 25°C, the salt dissolves completely. Considering that the solubility of NaCl at 25°C is 357g/L, what the student observes confirms that NaCl has reached its solubility limit at this temperature. Based on this context, describe what the 'solubility limit' is and explain the relationship between the phenomenon of solubilization and the temperature variation. Additionally, calculate the maximum amount of NaCl that could be dissolved in 1 liter of water at 40°C, knowing that the solubility of NaCl at this temperature is 395g/L.Answer sheet:

A chemical laboratory received a sample of a new metallic oxide, and the scientists must determine the chemical formula of the compound based on its properties. The sample reacts with water, forming an acid that, when analyzed, reveals the presence of hydrogen and a metal that behaves as a divalent metal in its reactions. Additionally, the sample reacts with diluted hydrochloric acid, forming a metal chloride and water. If the mass of the metal present in the sample is 27g, determine the chemical formula of the metallic oxide and explain the reasoning used, including the nomenclature of the compounds found.
