Sublimation is the change of state from a solid to gas, or liquid to solid on cooling. The type of mixtures that can be separated by means of sublimation, are mixtures of solids; (e.g. Sodium Chloride, and Ammonium Chloride.).

A broader definition of corrosion is the destructive attack on a metal through interaction with its environment. It is the process by which metallic atoms leave the compounds in the presence of water or gas. Metal atoms leave the metal until it fails or erodes from oxidation.
The tendency for oxidation is dependent on the metal. Metals used in construction, such as steel and copper alloys, are both subject to corrosion. Metals are chemical combinations of multiple elements. These metals are highly vulnerable because of the high energy content of the elements used in metallic form. The energy content is higher than that of their ores, allowing corrosion to become a natural process. Through being present in their natural environments, the ores in the metal revert back to their original form. For example, iron in moist air becomes iron oxide.
The resulting rust is a generic term for when iron corrodes. The reaction between iron and water causes rust to form on a metal object.
I hope this helps you!
Answer : The number of moles of is 0.6156 moles.
Solution : Given,
Mass of = 186.7 g
Molar mass of = 303.256 g/mole
Formula used :
Now we have to calculate the moles of .
Therefore, the number of moles of is 0.6156 moles.
The answer is A because I just answered it
Answer: Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
