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:

The equation is balanced

Explanation:

Before a equation can be said to be balanced the number of mole at the reaction side must be equal to number mole at the product side

Let's start with Zn at the reactant side 4 moles of Zn reacts and 4 moles of Zn was obtained from the product side which makes it balanced

Let's take HNO3

For H,10 moles react and 10 moles was obtained in the product side

For N,10 moles react and 8 moles was obtained initially and 2 moles was obtained as well which makes it 10 moles and it makes it balanced

For O,30 moles react and after calculating the total amount of O at the product side it was observed to be 30 which indicates that the equation is balanced...

The equation is absolutely well balanced
