If you have a mixture made of two substances one with a higher density than the other how could you separate the substances in a mixture?
Winnowing. Run the powder through a sifting grid, and allow it to fall into a box below. Set up a fan to blow sideways. The dense particles are more likely to fall into the box, while the less-dense particles are more likely to be blown off to the side.
You will probably need several iterations of this.

What property does separation by density rely on to separate out parts of a solution?
Separation by density relies on the property that different substances have different densities, causing them to settle at different levels in a solution. With this property, substances of higher density will sink to the bottom while substances of lower density will float to the top, allowing for separation based on these differences.
Is true about density and states of matter for most substances?
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
What is true about density and states of matter for most substances?
The density of solid state of matter is higher than the density of liquids and the density of liquids is higher than the density of gases.
What is a substance that has a mass of 45 kg and a volume of 43 m3?
There is no element or common compound with a density of 45kg/m3 = 1.047 kg/m3. But it could be a mixture of two or more substances: at least one of which has a higher density and at least one has a lower density.
How do properties help us identify substances?
If you wish to separate the constituents of a mixture, knowledge of the properties the constituent substances will help you figure out how to go about separating them. If you have any property (solubility in water, for example) that applies to at least one of you substances, and doesn't to another, you can use the property to separate them. If you wish to separate a solution, knowing the solubility curves of each solute will allow you to separate by changing the temperature. For example, Potassium nitrate has a much higher solubility in water than sodium chloride at high temperatures, but at or near zero degrees Celsius, it has much less. So, if you had a solution of sodium chloride and potassium nitrate, you could lower the temperature drastically and most of the potassium nitrate will precipitate. This is but one example. If you have a solid mixture, and a certain number of the substances in it will dissolve in water (or any other solvent), washing the mixture with the solvent will dissolve those, leaving everything else behind (you could filter the solvent out to separate the substances which don't dissolve) If your substances are physically different in size, you could pass the mixture through a sieve (for example, to separate sand and gravel). If one of your substances is magnetic, but others aren't, you could use a magnet to separate them.

If you have two substances that are the same size and have similar densities how ever they have different boiling points how would you separate them?
You can separate them by a process called fractional distillation. This involves heating the mixture to a temperature in between the boiling points of the two substances. As the mixture heats up, the substance with the lower boiling point will vaporize and rise, while the substance with the higher boiling point remains liquid. The vapor is then collected, cooled, and condensed back into liquid form, resulting in the separation of the two substances.
What causes certain liquids to float above others?
the density of each of the fats. the higher density, the lower it will be in a mixture
What is the relationship between density and buoyancy for objects and substances?
Density and buoyancy are inversely related. Objects or substances with higher density than the fluid they are placed in will sink, while objects with lower density will float. This is due to the buoyant force exerted on an object being equal to the weight of the fluid displaced, which is dependent on the density of both the object and the fluid.
