What else can I help you with?
What physical property would be the most useful in the separation of fine saw dust and salt?
Magnetism would be the most useful physical property for separating fine saw dust and salt. However, since neither is magnetic, a process of dissolving the salt in water, filtering out the saw dust, and boiling away the water is necessary.
Which physical property would be the most useful in identifying a sample of galena?
The most useful physical property for identifying galena would be its metallic luster and its high density. Galena has a metallic luster and is one of the densest minerals, so these characteristics can be helpful in distinguishing it from other minerals.
What property of these metals would allow such a separation?
The different melting points of the metals would allow separation by heating the mixture to a temperature where one metal melts while the other remains solid, enabling them to be physically separated.
Is the lower density of ice a physical or chemical property?
That would be a physical property.
Would malleability be a chemical or a physical property of matter?
Malleability is a physical property.
Would colorless water be described as a physical or chemical property?
physical property
Is vinegar a physical property?
ummm, no. If you are asking what a physical property of vinegar is, the answer would be its transparency.
Is reactivity an example of a physical property?
no. that would be a chemical property
Is wood a physical property or a chemical property?
Physical. If you were to cut that piece of wood in half what would it be? Still wood. There would be no chemical change. Just a physical change.
What property can be observed without destroying the substance?
This type of property is a physical property.
Is freeze-drying a physical property or a chemical property?
i would think physical, unless there is a chemical change occurring..... :)
Why would a screen be useful for separating a mixture of gravel and diatomaceous -earth powder?
A screen would be useful because it allows for the physical separation of different particle sizes. The gravel, being larger in size, would remain on top of the screen while the finer diatomaceous earth powder would pass through, effectively separating the two components of the mixture.
