Only pure substance are homologous,true or false? Can you please explain too?
Do you know the definition of a homologous series? Do you know an example of a homologous series?
Homologous means a mixture of same substance.e g Iodide crystals
False.
Pure substances can be homogenous or heterogenous.
A pure substance is a substance that is made up of only one type of particle. It can either be an element or a compound.
Homogeneous pure substances are composed of particles that are uniformly distributed throughout the substance, meaning that they have the same composition and properties throughout. For example, pure water (H2O) is a homogenous pure substance because all the water molecules are the same and have the same properties.
Heterogeneous pure substances, on the other hand, have particles that are not uniformly distributed throughout the substance. The composition and properties of these substances can vary from one part to another. For example, a mixture of sand and iron filings is a heterogeneous pure substance because the particles of sand and iron filings are not evenly mixed and have different properties.
Therefore, it is incorrect to say that only pure substances are homologous, as pure substances can be either homogenous or heterogeneous.
