Which of the following underlined items is not an intensive property? the melting point of aluminum metal is 933 k. a chemical reaction requires 3.00 g of oxygen. the density of helium at 25°c is 1.64 × 10-4 g/cm3. solid copper hydroxide is blue colored.

"A chemical reaction requires 3.00 g of oxygen" is not an intensive property.

Explanation:

The intensive property of a substance is that property which does not depend on the mass or the amount of the substance.

The melting point of aluminum metal is 933 K.

The melting point of a substance does not depend on the amount of that substance, therefore, this is an intensive property.

A chemical reaction requires 3.00 g of oxygen.

It includes the mass of the oxygen, i.e., the amount of oxygen required from the reaction, therefore, it is not an intensive property.

The density of helium at 25°C is 1.64 × 10-4 g/cm3.

The density does not depend on the amount or mass of the substance, therefore, it is an intensive property.

Solid copper hydroxide is blue colored.

The color of a substance does not depend on its amount, therefore, it is an intensive property.

it consists of the house of representatives and the senate.

explanation:

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
