a pure substance
Yes, a pure substance is a substance that is made up of only one type of particle. This means that all particles in a pure substance are identical in terms of their chemical composition.
a pure substance
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.
In the particle theory of matter, a pure substance is made up of only one type of particle, either an element or a compound. A mixture, on the other hand, is made up of two or more different substances physically combined together, with each substance retaining its distinct properties.
I thought it was pure substance. But i recently took a Science Test of these subject(i'm also in 8th grade) and it was the same question...EXACTLY! I put down Pure substance as well but appearantly the answer was "All of the Above" which included A.Pure Substance B.Compound C.Element ... so as long as you can prove it was only pure substance( This was for extra credit to get points back on the test for my teacher) You got the points. In my opinion a Pure Substance is the substance in which there is only one type of particle. I hoped this helped :)
The answer is likely supposed to be "an element", but ANY chemical substance contains only one type of particle, whether it is an element (atoms) or a compound (molecules). It is only combinations of elements or compounds (alloys, solutions, mixtures) that contains multiple types of particles.
Hydrogen is a pure substance because it is a single element made up of only 1 type of particle.
Matter that contains only one type of particle is known as a pure substance. For example, an element like hydrogen consists solely of hydrogen atoms, while a compound like water is made up only of water molecules. In contrast, mixtures contain two or more different types of particles. Thus, pure substances are the only kind of matter that can contain only one type of particle.
A pure substance is a material made of only one type of particle, element, or compound. It has uniform and constant physical and chemical properties, meaning it does not vary in composition or characteristics throughout the sample.
Yes, it is the compound Sulfur trioxide. Hint: If it has a chemical formula (with no + or - at the end) it is a pure substance.
A pure substance is constant in composition throughout, meaning it is made up of only one type of particle or element. This distinguishes it from a mixture, which contains two or more different substances that are physically combined.
