Can the chemical properties of a substance be observed without changing the substance?
physical properties
Is there a way to decide whether a chemical is a gas or liquid just by looking at its physical properties?
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
At room temperature potassium is classified as?
a solid just as one of the properties of metals states.
How do you identify if a substance is metal matalloid or non metal?
In simple terms just by looking at them, and doing an electrical conductivity test you can tell the following. the metals are shiny and conduct electricity. The non-metals which are gases or liquids are easy to distinguish. The solid non metals such as sulfur are not shiny and do not conduct electricity. (graphite conducts electricity but is soft and not that shiny). The metalloids look a bit like metals but are very poor conductors of electricity.
What are some physical and chemical properities of paper that can be observed?
The physical properties I know of are the shape which are either a square or rectangle, the color which is either white or different colors. The chemical properties I know of are just before you make the paper, that's pretty much it...

Name 5 physical properties of matter that can be observed?
There are many different physical properties of matter that can be observed. Consistency, color, and texture are just 3 properties.
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
How are medolloids different to medals and non medals?
metalloids are different from metals and non metals as they consist the properties of both metals and non metals. but they cannot put under any of the catergories. just a metalloid

Give one property that is typical of non metals?
Physical properties of nonmetals are generally just the opposite of metals so: - No luster (dull appearance) - Not ductile - Low density - Low melting point - Poor conductor - Not malleable The chemical properties of non metals just tend to gain electrons Hope that helps
Do metaloids contain metals and nonmetals?
Metalloids do not contain either metals or nonmetals. They are elements that have properties of both metals and metalloids, and are found between the metals and nonmetals on the periodic table.
Why aren't metalliods just considered metals or nonmetals?
They have properties of both so it would be inaccurate to specify metal or nonmetal
How do you differentiate metals from non metals?
Metals usually have a characteristic lustre, so you can often tell just by looking. The metals conduct electricity when solid, and non-metals, with the exception of graphite, do not. Metals react with oxygen to give basic oxides, whereas non-metals give acidic oxides.

What is a scientist looking at when he is using a microscope to view a crystalline structure?
One possible answer is he/she is looking at the crystal structure that forms in a metal lattice, or just metals. These crystals can vary in size by the processes of quenching, anealling and tempering, larger, moderate and smaller respectively. The crystal sizes can vary the properties of the metal, making it more ductile, harder, brittle, softer, etc.
