Question

Marianne wants to study the chemical properties of iron. How could she do this?

A. Marianne could hit the sample with a hammer.
B. Marianne could observe the sample's reactivity with moist air.
C. Marianne could find the mass of the sample by using a balance.
D. Marianne could find the density of the sample by dividing its mass by its
volume.

Answer 1

Marianne can study the chemical properties of iron by observing its reactivity with moist air, finding its mass, and determining its density.

Step-by-step explanation:

Answer:

In order to study the chemical properties of iron, Marianne could observe the sample's reactivity with moist air. Iron reacts with moist air to form iron oxide (rust), which is a chemical change. This observation would provide insight into the chemical behavior of iron.

Additionally, Marianne could find the mass of the iron sample by using a balance. This would allow her to determine the amount of iron present and perform further calculations.

Lastly, Marianne could find the density of the iron sample by dividing its mass by its volume. Density is a physical property that can help characterize the chemical nature of a substance.
