What else can I help you with?
Is a glass tube physical or chemical?
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
If the elements of the periodic table were sequenced by density from smallest to largest what would they have in common Would they have similar chemical and physical properties?
Each chemical element has specific chemical and physical properties.
Can you tell the chemical properties of a can by looking at a picture whether it is a tin can aluminum can or a crushed can?
No, you cannot determine the chemical properties of a can just by looking at a picture. Different metals like tin and aluminum have distinct physical properties, but to identify the exact metal used in a can, you would need to perform a chemical analysis or consult the manufacturer's specifications.
What type of chemist would describe the chemical properties of oxygen?
Since oxygen is an inorganic substance, most likely an inorganic chemist would describe the chemical properties of oxygen.
What is changed when making up a complex polymer that would result in a compound with different chemical properties?
The number of monomers in the polymer is variable.
Is a glass tube physical or chemical?
A glass tube is physical. Its composition, structure, and properties can be changed without altering its chemical composition, unlike a chemical change which would involve a change in composition.
Dough changing into a donut would be physical?
yes, and no. Its physical properties do change, but its chemical properties alter as well, due to the fact that the frying alters the yeast molecules in such a way that taste, formation of molecules, and chemical properties as w whole are all changed. So to answer the question, not completely, but yes.

What is the physical changes in matter?
Physical changes in matter are when physical properties are changed. Some physical properties are size and color. When a physical change in matter occurs, the material may have changed size (gotten smaller) due to weathering and erosion. Chemical changes are when the chemical composition of a substnce is changed. For example a chemical change would be iron turning into rust due to the process of oxidation
Would it be correct to say that helium has no chemical properties?
no

Why it would be coreect to say that helium has chemical properties?
But of course. One of its properties is that it is very unreactive.
What is the smallest quantity that a chemical compound can be divided into and still maintain its chemical properties?
The general answer would be molecule however some molecules prefer to exists as paired molecules and subdividing them would alter some of its chemical properties: a good example of this would be the sugars.
What are the chemical and physical properties of dental amalgam?
coefficient of thermal expansion chemical would be Galvanism,
