hydrocarbons, they are called isomers
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
Freezing leftovers is a physical change, not a chemical change. When leftovers are frozen, the molecules rearrange to form a solid structure, but the chemical composition of the food remains unchanged.
Naphthalene is considered a pure substance because it is a chemical compound made up of only naphthalene molecules. It has a definite and consistent chemical composition, with uniform properties throughout its structure.
Slicing turkey represents a physical change, not a chemical change. The chemical composition of the sliced turkey is identical to the chemical composition of the intact turkey. Only a physical change has taken place.
A trihydrate salt is a salt that contains three water molecules within its crystal structure. These water molecules are bound to the salt compound, which results in a specific chemical composition for the salt. Trihydrate salts are commonly found in nature and can also be formed through chemical processes.
isomers
Isomers are pairs of molecules that share the same chemical formula but have different structural arrangements. For example, glucose and fructose both have the chemical formula C6H12O6, but they have different structural arrangements.
When two molecules have different configurations but the same atomic composition the two molecules cannot be said to have the same physio-chemical properties. In fact, a simple rearrangement, even with identical chemical formulas, can drastically change the properties of a substance.
The chemical composition is identical but the physical structure of the crystalline forms can vary in many ways depending on the condition of the environment where they were formed (temp, pressure, etc.)
Chemistry is the study of chemical composition of materials, of chemical reactions, of the structure of molecules, of molecules synthesis, etc. Chemistry is close to physics, mineralogy, biology.
Yes, formaldehyde is considered a homogeneous compound because it consists of identical molecules throughout its structure. Its chemical composition is consistent and uniform, making it a homogeneous substance.
Molecules in a chemical compound can be identified by analyzing the elements present in the compound and their arrangement. Techniques such as spectroscopy, mass spectrometry, and nuclear magnetic resonance (NMR) can be used to determine the structure and composition of molecules in a compound.
Freezing leftovers is a physical change, not a chemical change. When leftovers are frozen, the molecules rearrange to form a solid structure, but the chemical composition of the food remains unchanged.
A chemical formula is representative for the molecule composition.
A ruby is a naturally occurring crystal of the mineral corundum. Rubies can also be created in laboratory settings as well. The chemical composition and crystalline structure is identical.
Breaking a vase is a physical change because the chemical composition of the vase remains the same. The bonds between the molecules are simply physically broken, but the chemical structure of the vase does not change.
Chemical analysis determine that the chemical composition is identical.
