The pure substance picture represents a material consisting of only one type of particle, which can be either an element or a compound. In this model, all particles are uniform in composition and properties, leading to consistent physical and chemical behaviors. For example, pure water (H₂O) will have identical molecules throughout, exhibiting uniform boiling and melting points. This concept is crucial for understanding phase changes, reactions, and the behavior of substances in various conditions.
Ice is solid H2O so it is a pure substance, at least ideally.
it is a pure substance.... not
Methane is a pure substance.
No, sweat is not a pure substance. It is a mixture of water, salts, and other substances like urea and ammonia.
Yes, purified water is a pure substance because it consists of only water molecules with impurities removed through processes like distillation or filtration. This makes it a homogeneous mixture with a consistent composition.
It is a gas and it doesn't really have a pure substance that you can see.
No, anything with atoms of a single element is a pure substance. For example (DO NOT TRY IT), but JUST picture a glass filled with mercury (Hg). if there are only Hg molecules, then it is a pure substance.
The terms element and compound are used to identify pure substances.
pure substance, propanone
Pure Tin is a metallic element with the symbol Sn.Tin is always pure. Tin is not a mixture, but it may be a part of a mixture, like in bronze
Ice is solid H2O so it is a pure substance, at least ideally.
Matter is just like a pure substance because you have your own space and own kind of compound
Pure substance
it is a pure substance.... not
Methane is a pure substance.
In Geology that is a mineral, generally that is an element, look to PERIODIC TABLE.
No, sweat is not a pure substance. It is a mixture of water, salts, and other substances like urea and ammonia.
