Answer 1

Answer:

1.an alloy is a mixture of two or more metal{ or a metal and a small amount of non metal}

eg.brass is an alloy of two metal Copper and Zinc

The properties of an alloy are different from the properties of metal :

1.alloys are harder than a metal

2.alloy are stronger than the metal which they are made

3. alloy are more resistant to corrosion

2. Reactivity series of metal

some metal are chemically very reactive where some are less reactive or unreactive .

the arrangement of metal in a vertical column in order to decreasing reactivity is called reactivity series of metal

Answer 2

Alloys are made to: Enhance the hardness of a metal: An alloy is harder than its components. Pure metals are generally soft. The hardness of a metal can be enhanced by alloying it with another metal or nonmetal❤️
