Raya collected data about a substance. She noted that: -- its density is 10 g/cm3 -- its melting point is 200 degrees celcius -- it reacts with oxygen -- its color is blue-green Which property that she observed is a chemical property?
A) its density is 10 g/cm3
B) its melting point is 200 degrees celsius
C) it reacts with oxygen
D) its color is blue-green
I need helpp
I think is C, since reacting with oxygen is a chemical property
The chemical property that Raya observed is option C) it reacts with oxygen.
To determine this, you can analyze the given properties and identify which one involves a chemical change or reaction.
Option A) Density is a physical property that describes how much mass is contained within a given volume. It does not involve any chemical changes or reactions.
Option B) Melting point refers to the temperature at which a substance changes from a solid to a liquid state. While it does involve a change in state, it is still considered a physical property rather than a chemical property.
Option C) Reacting with oxygen indicates a chemical property. When a substance reacts with oxygen, it undergoes a chemical reaction that results in the formation of new substances with different properties. This chemical change is a characteristic of a chemical property.
Option D) Color, in this case blue-green, is a physical property. While color can sometimes change in certain chemical reactions, it alone does not indicate a chemical property in this context.
Therefore, the correct answer is option C) it reacts with oxygen, which is a chemical property.
