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.

Explanation:
Since, NaCl exists as and in solution. Therefore, Van't Hoff factor (i) will be equal to 2.
Now, we assume that there are "n" moles of NaCl in the given solution. And, we assume that there is 1 kg of solvent (water).
So,
0.264 =
n = 0.132
Also, moles of water will be calculated as follows.
Moles of water =
= 55.56 mol
Hence, mole fraction of NaCl is calculated as follows.
Mole fraction =
=
Hence, mole fraction of NaCl will be .
At , the vapor pressure will be calculated as follows.
71.9 - p = 18.98
p = 52.92 torr
Therefore, vapor pressure of the given solution is 52.92 torr.
Metals:
<span>Distinguishing luster (shine)
</span><span>Malleable and ductile (flexible) as solids
</span><span>Conduct heat and electricity
</span><span>Metallic oxides are basic, ionic
</span><span>Cations in aqueous solution
</span>
Nonmetals:
<span>Non-lustrous, various colors
</span><span>Brittle, hard or soft
</span><span>Poor conductors
</span><span>Nonmetallic oxides are acidic, compounds
</span><span>Anions, oxyanions in aqueous solution
</span>
They have luster, good thermal and electrical conductivity, high densities and melting points, and are malleable. The only exception would be mercury most metals are solid at room temp
Based on the information provided in this image shown above, the measurement to two (2) significant figures is equal to 3.50 mm.
<h3>What is measurement?</h3>
Measurement can be defined as an act or process through which the size, magnitude, dimensions, or distance traveled by a physical object or body is taken, especially for the purpose of an experiment.
<h3>What is a scale of measurement?</h3>
A scale of measurement can be defined as a classification which is used to illustrate the attributes of the values that are assigned to variables associated with a data set.
<h3>What is a
significant figure?</h3>
In Mathematics, a significant figure can be defined as the number of digits in a numerical data (value), typically a measurement, which enhances its degree of accuracy.
Based on the information provided in this image shown above, the measurement of the film to two (2) significant figures is equal to 3.50 mm.
