EVERYDAY SCIENCE

Detailed explanation-1: -The correct answer is Option(3) i.e.Chemical property. The chemical property of an element has the ability to react with an acid or gases.

Detailed explanation-2: -Reacting with Acids The ability of a substance to react with an acid is a chemical property. Some metals react with various acids to form compounds.

Detailed explanation-3: -A chemical property describes the ability of a substance to undergo a specific chemical change. Unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. A chemical change is also called a chemical reaction.

Detailed explanation-4: -Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. Some physical properties, such as density and color, may be observed without changing the physical state of the matter.

Detailed explanation-5: -The properties that are most useful in identifying a substance, such as density, solubility, and reactivity with acids, are its characteristic properties. The characteristic properties of a substance are always the same whether the sample you’re observ-ing is large or small.
