A pure substance is made up of only one type of particle, while a mixture is composed of two or more different substances physically combined. Pure substances have a fixed chemical composition and properties, while mixtures can have varying compositions and properties depending on the amounts of each substance present.
A pure substance is an element or a compound. An element is composed of the same kinds of atoms, and compounds are composed of atoms of different elements chemically bonded, having a definite composition. A mixture is composed of substances that are not chemically bonded and does not have a definite composition.

What change will show in a graph in temp of an substance a s it is heated will show what?
As a substance is heated, its temperature will increase in a linear manner until it reaches its melting or boiling point, at which point the temperature will remain constant as the substance changes phase. This will appear as a straight line with a plateau on a temperature vs. time graph.
Are there any items from Poole Silver Co that are pure silver vs plated silver?
The majority of items from Poole Silver Co are silver-plated rather than pure silver. Pure silver items are rare from this manufacturer. It is crucial to check the specific product descriptions or markings to confirm whether an item is pure silver or silver-plated.
How can you determine the melting point of a substance based in its heating curve?
The melting point of a substance can be determined based on its heating curve by identifying the temperature at which the substance transitions from a solid to a liquid, which corresponds to a plateau in the heating curve where the temperature remains constant while the substance is melting. This plateau is known as the melting point.
Homogeneous vs heterogeneous?
Homogeneous refers to a substance that is uniform in composition, where the components are evenly distributed (e.g. saltwater). Heterogeneous refers to a mixture that is not uniform throughout, with different components visibly distinct (e.g. a salad).
How do you graph mass vs volume?
To graph mass vs volume, plot mass on the y-axis and volume on the x-axis. Each data point will represent a specific object or substance, showing how mass changes with different volumes. The relationship between mass and volume can help determine density, which is a key property of the material being examined.
Do the sugar and water form a pure substance or do they form a mixture?
Well a mixture is like a salad, you can pick out the tomatoes, the lettuce, the olives and what not. If you have sugar plus pure water you definitely can't take out the sugar out of the water, unless you have some super scientifical machine (: . I'm not quite sure what a pure substance is but I would say that it is a pure substance because it can't be a mixture.----------------------------------Sugar water is an example of a solution, which is classified as a homogeneous mixture (vs. mechanical mixture like salad). Water and sugar are both pure substances and when they are combined through physical means (dissolution is a physical process) they make a mixture. Sugar and water can be easily separated through evaporation.Water plus sugar=carbon dioxide
Is Pure water a homogeneous or heterogeneous?
Heterogeneous vs. homogeneous refers to solutions. Pure water is a compound which is bound together chemically. Solutions are combined physically. So technically it is neither.
What is a suspension vs liquid?
A suspension can be separated and does not mix together, but emulsion does mix together. A suspension can be separated but an emulsion cannot be separated.Emulsion: The mixture of substance is in one phase , so they can not be separated mechanically. Eg: ShampooSuspension: The mixture of suspension is not in one phase , so they can be separated mechanically.eg: Mixture of oil& water.
What makes an element vs a compound homo or hetero?
A pure element or a pure compound are homogeneous.
What is a substance that enters earth's cycles and does harm to living things is?
zakaria vs flaw
What are the release dates for Rock Star INXS - 2005 Style vs- Substance 1-5?
Rock Star INXS - 2005 Style vs- Substance 1-5 was released on: USA: 19 July 2005 USA: 2005 USA: July 2005
Solute and solvent?
The solvent is the substance that is dissolving something else. The solute is what is being dissolved. For example, if you were dissolving salt in water. The water would be the solvent and the salt would be the solute.
Is ammonia a consumer or a producer?
Consumer vs producer is not an applicable categorization for Ammonia. Ammonia is a substance, a chemical compound.
How easily a substance will dissolve?
The quality of a substance describing its ability to solvate is solubility. Solubility varies by polar vs nonpolar substances, concentrations, and other factors that include the temperature of the solvent.
How many elements can occur in nature?
Clarification needed: How many are found un-bound (pure) in nature? For example: pure gold nuggets, atmospheric nitrogen, etc. Or how many are naturally occurring on Earth (even if they're in compounds and not pure) vs. how many are created only by humans in a lab?
What do phase diagrams describe for a particular substance?
Phase diagrams describe the relationship between temperature, pressure, and the phase of a substance (solid, liquid, gas). They show the conditions under which a substance exists in different phases or transitions between phases.
What is mean by weight by weight?
"weight by weight" is term, we use in chemistry. it is similar to terms like molarity, molality, normality etc. "weight by weight" defines the ratio of solute vs solvent in solution or mixture specially when we deals with solid in solid mixture or solution
