What is chalk considered in terms of its chemical composition and physical properties?
Chalk is primarily composed of calcium carbonate, a chemical compound made up of calcium, carbon, and oxygen atoms. It is a soft, white sedimentary rock that is easily crumbled into a fine powder. Chalk is known for its ability to write smoothly on surfaces and is commonly used for writing and drawing.
What else can I help you with?
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.
Is the solubility of a substance in water primarily determined by its chemical composition or its physical properties?
The solubility of a substance in water is primarily determined by its chemical composition rather than its physical properties.
Is taste a physical or chemical?
Taste is derived from the chemical composition and chemical properties of a material.
What determines the physical properties of minerals?
The physical properties of minerals are determined by their chemical composition and atomic structure.
Is a glass tube physical or chemical?
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Would a reaction with oxygen be a chemical or physical property?
A reaction with oxygen would generally be considered a chemical property because it involves a change in the chemical composition of the substances involved. Physical properties, on the other hand, do not involve changes in chemical composition.
Matter that has a fixed chemical composition and distinct properties is a?
Physical mixture
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
Are properties such odor color density and solubility physical or chemical properties?
Color and density are physical properties. Odor and solubility are chemical properties.
Which type of properties is easier to recognize physical or chemical?
Physical properties are generally easier to recognize compared to chemical properties because physical properties can be observed or measured without changing the substance's chemical composition. Examples of physical properties include color, size, shape, density, and melting point.
