What else can I help you with?
Is weathering rocks chemical or physical change?
Weathering of rocks can involve both chemical and physical changes. Physical weathering involves the breakdown of rocks without changing their chemical composition, while chemical weathering involves the alteration of a rock's chemical composition through reactions with water, air, or other substances.
Why is the chemical composition of a mineral important?
The chemical composition of a mineral is important because it helps identify the mineral and provides information on its physical and chemical properties. Understanding the composition can help determine how the mineral formed, where it is found, and how it can be used in various applications.
Do minerals have chemical compositions?
Yes. Every mineral has a chemical composition.
Does a compound have a chemical composition?
Yes
What is the chemical composition of ammonia?
The chemical composition of ammonia is NH3, which means it is made up of one nitrogen atom and three hydrogen atoms.
Why there is no such a thing as chemical formula of air?
Because air is a composition of all kinds of gases and is different everywhere.
Is a tire losing air a chemical reaction?
No, a tire losing air is a physical phenomenon caused by air molecules escaping through tiny holes or leaks in the tire. This is not a chemical reaction because it does not involve a change in the chemical composition of the tire or the air.
When water evaporates its chemical composition?
The chemical composition remain unchanged.
Is a form of green carbonate when exposed to moist air a physical property or chemical property?
This is a chemical property. The reaction of green carbonate with moist air to form a different substance involves a change in the chemical composition of the substance, indicating a chemical reaction.
Is the air is often blended into ice cream to give it a lighter texture a physical or chemical and why?
Blending air into ice cream to give it a lighter texture is a physical process. This is because air being incorporated into the ice cream does not change the chemical composition of the ingredients; it just alters the physical structure by introducing air bubbles to create a lighter texture.
Is weathering rocks chemical or physical change?
Weathering of rocks can involve both chemical and physical changes. Physical weathering involves the breakdown of rocks without changing their chemical composition, while chemical weathering involves the alteration of a rock's chemical composition through reactions with water, air, or other substances.
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What is the chemical composition of a flame?
A flame is pure energy so it has no real chemical composition except from the chemical compositions of the oxygen and fuel (usually hydrocarbons) needed for it to burn. A flame requires fuel, oxygen and heat energy, although it gives off light and heat energy as well. The act of burning is reacting the fuel with oxygen in the air but the flame itself has no chemical composition.
Groups of rocks are classified by?
i think is chemical composition its not chemical composition, it's how they were formed
The groups of rocks are classified by?

Are rocks a chemical makeup?
Yes, the composition of the rocks is as a result of the distinct chemical composition.
Is reacting to air a physical or chemical property?
Reacting to air is a chemical property because it involves a change in the chemical composition of the substance when it comes into contact with oxygen in the air, leading to the formation of new compounds. It reflects how a substance interacts with its environment on a molecular level.
