A scientist has analyzed the chemicals that make of sample of an unknown substance Which chemicals would be the best indicator that the unknown substance is a plant?
Cellulose and starch
The difference between a pure substance and a homogeneous misture?
Pure substance: matter w/properties/composition that don't vary from sample to sample. (salt, water,etc). Homogeneous mixture: composition can vary; an example is a solution (coffee w/sugar) and is uniform throughout.
What is a characteristics of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
What is an example for an intensive property?
Intensive properties are those properties that are independent of mass or size. Examples would be temperature, density, etc. Regardless of how much you have, the density is the same, and the temperature is the same.
Is it true that the density of a substance is the same for all samples of the substance?
No, as density also depends on the state of matter in the sample of the substance.
Sample of matter that has the same composition and properties throughout?
term for that is pure substance
What is a sample if matter that has the same composition and properties throughout what?
"A phase is a state of a...system that has...uniform chemical composition and physical properties.""Matter." Wikipedia. 19 Feb 2008, 04:16 UTC. Wikimedia Foundation, Inc. 19 Feb 2008 .
What is a sample of a matter either single element or a single compound that has a definite chemical and physical properties?
a pure substance. :)

How can you use Dalton's atomtic theory to explain why every sample of a pure substance has the same properties?
A pure substance is a kind of matter which is not mixed with any other solution or substance and can't be saperated futher.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
The difference between a pure substance and a homogeneous misture?
Pure substance: matter w/properties/composition that don't vary from sample to sample. (salt, water,etc). Homogeneous mixture: composition can vary; an example is a solution (coffee w/sugar) and is uniform throughout.
What two properties can be measured for any sample of matter?
Mass
Is every sample of matter substance?
Every sample of matter is not a substance because a matter may include multiple substances. A substance contains only one kind of matter.
How does properties can be observed only when the substances in a sample of matter are changing into different substances?
Chemical properties
