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.

What is the difference between a characteristic property and non-characteristic property?
PHYSICAL (smell, color, texture, size, etc)--NON CHARACTERISTIC GENERAL (general stuff about the substance all together)-CHARACTERISTIC Characteristic properties help us identify pure substances or the group it belongs to. Non-characteristic properties cannot help us identify pure substances or the group it belongs to.
Properties help us identify matter?

Why is it helpful to know the the physical and chemical properties of a substance?
In is impossible to work with materials, substances etc. without a deep knowledge of all chemical and physical properties. And all around us: foods, building materials, electronics, cars, drugs are composed from materials with specific properties.
Is possible to create more than one dichotomous key for classifying and identiying of object?
yes because it help us to identify them easily.
What are the Physical and chemical properties of timber?
the chemical properties of timber tell us about the chemical composition of tree material and physical properties tell us about the apperence and color of the timber

What properties of substances can you observe and how do these properties determine the usefulness or hazards of a substance?
You can observe physical, chemical, and characteristic properties of a substance and can be used to determine the usefulness of a substance by, giving us information about the substance usually using our 5 senses which are physical properties. Or being able to describe the substances ability to undergo changes to its composition to produce one or more new substances, chemical property. Or even just being able to identify whether or not the substance is pure or not can help us determine if the substance is hazardous or not. two other properties I did not mention were the qualitative and the quantitative properties.
How are physical and chemical properties of matter useful?
Physical and chemical properties of matter are useful because they can help you identify that substance. For example paper burns very easily and aluminum doesn't, this is how they can be described individually.
What physical properties allow us to identify salt?
The taste
I found a moth last night can anyone help me identify it?
We cannot see what your moth is, so it will be impossible for any of us to help you identify it.
