What is mixture?Write the differences between homogenous and heterogenous mixture |
Answer» <p>AMIXTUREis a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other. Most natural substances are mixtures.The termsheterogeneousandhomogeneousrefer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their compositionAhomogeneous mixtureis a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout. There is only onephase of matterobserved in a homogeneous mixture. So, you wouldn't observe both a liquid and a gas or a liquid and a solid in a homogeneous mixture.Aheterogeneous mixtureis a mixture where the components of the mixture are not uniform or have localized regions with different properties. Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).</p> | |
