a pure substance. :)
Each chemical compound has specific chemical and physical properties.
Salt is a chemical compound. It has chemical and physical properties.
Enantiomers..
The chemical and physical properties of a compound are different than those of the elements from which it is formed.
Sodium chloride is a chemical compound (NaCl), not a property.
What is the question exactly? If it is about Uranium having physical and/or chemical properties, the answer is that it has both. Every single element and compound in this universe has both physical and chemical properties.
Acetone is a chemical. It has both chemical and physical properties.
No, it is a pure substance. A "pure substance" does not mean an element. Rather, it means that the given substance has definite physical and chemical properties. "Pure substances" can be either "Elements" or "Compounds" because all substances belonging to these categories have definite physical and chemical properties.A mixture does not have definite physical and chemical properties, and combine in varying proportions.
a molecule
The elements of a compound combine to form new substances with properties that are different from the individual elements. This is due to the chemical bonds that form between the elements, resulting in unique physical and chemical characteristics for the compound. The properties of a compound are determined by the type of elements present, as well as the arrangement and strength of the chemical bonds within the compound.
A compound that has the same properties as the elements that formed it is called a pure substance. Each element retains its chemical properties within the compound, but the compound itself may have different physical and chemical properties compared to its individual elements.
Because reactants and products have different chemical compositions and consequently different chemical and physical properties.
