You would see if a substance is a mixture or a pure substance because a mixture is where 2 or more things are mixed together. A pure substance is where it could be made up of different atoms, or it could be made up of one substance. Just like honey. A pure substance can't have different ingredients, only different atoms.

is blood a mixture or pure substance , hetero or homogeneous?
Blood is a mixture because it is composed of different components such as red blood cells, white blood cells, platelets, and plasma. It is considered a heterogeneous mixture because you can see the individual components with the naked eye.
Is concrete pure substance or mixture?
Mixture
Is salt water a pure substance or a solution?
Pure NaCl, common salt, is a chemical compound and "one pure substance". (Table salt often has small amount of an iodide salt added for health reasons, and some anti-caking agent to make it flow better)
Is gold a heterogenous or homogenous mixture?
Gold is homogeneous, meaning composed of the same thing, / phase. like salt. Heterogeneous, composed of different. ie. ice + water
How is a pure substance different from a mechanical mixture or a solution?
A pure substance has only 1 type of particle and are rare, so they cost a lot of money.(eg. diamonds have only 1 type of particle) A solution is a mixture of 2 or more substances that is blended so well that it has one set one properties. Also, it is hard to separate the 2 substances from each other. (eg. water has 2 particles, but looks like 1) A mechanical mixture is a mixture of 2 or more substances and all the ingredients are visible to the naked eye. Also, it is easy to separate. (eg. chocolate chip cookies have many different types of particles, but you can see all the ingredients and are easy to separate the chocolate chips from the cookie.)
Is a pizza a mixture or a pure substance?
Its a mixture of predominantly carbon bases substances. It would be interesting to see that one on the periodic table.
What is the difference between pure substance and mechanical mixture and solutions?
1. A pure substance can not be separated farther since it is composed of one type of atom. 2. I can't define mechanical mixture... Check your text book 3. A solution is one or more substances. I can: As she said a pure substance has only one type of particle. A solution is MORE then one substance. But in a solution u can't see the different parts. In a mechanical mixture, there is more then one particle like in a solution, but u can see the different particles.
Is cheese a pure substance?

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
Suppose you have a pure substance. How can you tell whether it is a compound or a element?
It is really easy to identify a mixture when it's a formula and if it's to different colored substances. In a formula a MIxture will be joined by a plus sign. WHen you are actually working with two substances look for the difference between the two take sulfur and Iron for example, you can see the little yellow speects, so you know right away that it is a mixture. A pure substance you can't just look at it a know it's compound or an element you have to find out if it's homogenous( you can only see one substance) or is it's Heterogenous( you can see more than one) these two you can just look at it and see if it's one or the other. Milk would be and example of homogeneous because you can only see the white nothing else. Sulfur and iron would be and example of heterogeneous because you can see more then one substance(even though Sulfur and Iron together form a mixture) In a elements case you need to look at the Formula it's in like Ne would be an element because it's only one substance. Also if it was Ne2 it still would be one but it's proper name would be a diatomic element but still considered an element.A compound can always be addentified by it's formula it will have to element together without a plus sign in between(remember that is a mixture.
Is a pure gold coin a mixture or a pure substance?

Is raisin bread a heterogeneous mixture a solution a compound or an element?
I think that it is a mechanical mixture because the different parts (cerial, raisans, etc...) can be seperated and the cereal is mader up of different particles.
Is salt water a pure substance or a solution?
Pure NaCl, common salt, is a chemical compound and "one pure substance". (Table salt often has small amount of an iodide salt added for health reasons, and some anti-caking agent to make it flow better)
