Final answer:
Adjusting the proportions of substances in an alloy can significantly alter its physical and chemical properties, including hardness, boiling point, physical strength, and resistance to corrosion. These changes can cause phenomena such as rusting or shifting in acidity.
Explanation:
Changing the proportions of substances in an alloy impacts its properties. For instance, changing the ratios of iron, carbon, nickel, and other elements in steel, an alloy, can affect its physical strength and resistance to corrosion. It's crucial to understand that in any alloy, the relative compositions of different elements produce the character of the alloy. For example, in steel, altering the amount of carbon can change the hardness and tensile strength of the final product.
It's also important to know about the law of multiple proportions in chemistry. This law states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small whole numbers. In alloy formation, these proportions of mass can significantly affect the properties of the resulting alloy.
Physical and chemical properties, such as hardness and boiling point, can be altered by changing the proportions in an alloy. These shifts can lead to both physical or chemical changes, such as melting, freezing, rusting, or even changes in flammability and acidity.

Answer:
moles of NaCl per liter of solution.
Explanation:
- [NaCl] is an expression of the concentration of NaCl.
- If the concentration is the molarity;
Molarity can be defined as the no. of moles of solute dissolved per a 1.0 L of the solution.
- For [NaCl] is a symbol for: moles of NaCl per liter of solution.
Answer: moles of per liter of solution
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
where,
n= moles of solute
= volume of solution in L
Square brackets represents the concentration of a substance i.e. amount of solute dissolved per liter of the solution.
Thus represents moles of
per liter of solution.
