How would you define a substance based on what you have observed?
How would you define a subtancebased on what you have obsrved
What is a special type of mixture where a substance is dissolved into a liquid?
A mixture of solids would be something like for example; compost. It is made up of all solid parts, yet the parts are different. It would not be considered a liquid or a gas, as all parts are solid and have not changed.
What distinguishes a mixture form an impure substance?
If a substance in a mixture is preponderant--, if the amount far exceeds the amounts of the other substances in the mixture it is usually called an impure substance. Resource: Separation of the Components of a Mixture Lab -Chemistry
Process would be most appropriate to separate a mixture?
The process that would be most appropriate to separate a mixture is filtration. This only applies if the mixture is composed of a solid and a liquid.
How would you get solid salt back from salt and water mixture?
by heating

Is a saturated solution a heterogeneous or homogeneous mixture?
No. If a substance is soluble, it will dissolve in a solvent, which means you will not be able to visually distinguish it. This would be a solution, which is a homogenous mixture.
Is vegetable oil and water a pure substance or mixture?
It would be an mixture
What is a substance that can be be separated by physical means?
It wouldn't be a single substance, it would be a mixture.
Is brownie batter a mixture?
If dry, then solid. If moist, then liquid.
Is oil and water is substance or element?
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
How you differentiate substance from mixtures?
Substance would be what goes together with other substance to make a mixture.
Is a 14-k gold a homogeneous or a heterogeneous mixture?
Homogeneous mixture. If it was heterogeneous, the substance (s) would not be spread out evenly.
Is CuSO4 heterogeneous or homogeneous?
H2SO4 is sulfuric acid, which is a pure substance called a compound, which by definition is homogeneous matter, but is not a mixture, unless you dilute it with water, in which case it would be an aqueous solution of sulfuric acid, and would be a homogeneous mixture in that case.
A liquid changes back into a solid by freezing at what point?
The FREEZING POINT ----- which for a pure substance (as opposed to a mixture)is the same thing as the melting point since they are both the point at which the liquid phase of a substance would be in equilibrium with the solid. For a mixture, the two would be different and you would get a freezing point range that started at the freezing point and ended at the melting point
Is gas homogeneous heterogeneous or a pure substance?
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
Is table sugar added to a cup of coffee and stirred a pure substance or a mixture?
