What do scientists study to learn about the properties of stars?
Scientists study stellar spectra to learn about their properties such as temperature, chemical composition and relative chemical abundances, radial velocity, rotational speed etc.
How do scientists identify the chemical properties of a material?
Scientists use various analytical techniques such as spectroscopy, chromatography, and mass spectrometry to identify the chemical properties of a material. These techniques help in determining the molecular structure, composition, and behavior of the material at a molecular level. By comparing the results with known standards, scientists can identify and characterize the chemical properties of the material.
Why is acid making limestone fizz a chemical change?
When acid reacts with limestone, it causes a chemical reaction that results in the formation of new substances. This transformation is considered a chemical change because the original properties of the limestone and acid are altered, forming new chemical compounds. The fizzing is often a visual sign of this chemical reaction taking place.
Difference between a chemical and organic limestone?
Chemical limestone is synthetic and manufactured through chemical processes, often for specific industrial applications. Organic limestone, on the other hand, forms naturally from biological sources like shells and coral reefs, and is often used as a building material or in agriculture for soil improvement. Organic limestone may contain impurities from its natural formation, while chemical limestone can be tailored for specific composition and properties.
How can scientists use a chemical reaction to separate a fossil from limestone without damaging the fossil?
The limestone containing a fossil would be heaated to a sufficiently high temperature (about 1,800 centigrade).then the limestone would become powder and the fossil which is not as sensitive to heat as limestone would remain un damaged
Is acid on a limestone producing carbon dioxide gas a physical or chemical change?
The reaction of acid on limestone to produce carbon dioxide gas is a chemical change. This is because new substances with different properties (carbon dioxide gas and water) are formed during the reaction, changing the chemical composition of the limestone.
On what basis do scientists classify the minerals?
Scientists classify minerals based on their chemical composition, crystal structure, physical properties, and chemical properties. This classification helps them understand the characteristics of different minerals and how they form in nature.
Is limestone a chemical rock?
Yes limestone is a chemical rock
What are the uses Chemical limestone?
What are some uses of chemical limestone
What is chemical limestone made of?
Chemical limestone can form when calcite is dissolved.
Is chalk the same form of limestone?
The chemical formula is identical (CaCO3, calcium carbonate) but the physical and mineralogical properties are different.
Does each mineral have its own properties?
The properties are affected by its chemical composition, method of formation, crystal latticework, and environment surrounding its formation.
