How does the density of a 100-kg iron block compare with the density of an iron filing?
The density of iron is 7,874 kg/m3 or 7.874 g/cm3. The density of iron filing is somewhat lower depending upon how fine the filings are, but I guess more than 4000 kg/m3 or 4.0 g/cm3. The SI standard of density is measured in kg/m3. The density of a material is defined as its mass per unit volume. The density of iron does not change with the size of the sample. A bucket full of iron filings will have a lower density than the block because there will be air between the individual filings. The density of a deep pile of filings will be greater than a thin pile because the weight of the filings above compacts the filings below by pushing out some of the air. However, the density of each individual piece will still be the same as for the whole block.
What does it mean when there is physical change?
A physical change is one where no new substance is produced. Melting is an example of a physical change. When you melt iron, you get liquid iron, it's still the same chemical substance. If you melt copper, you get liquid copper, not liquid iron.
What element has the same properties as neon?
No other element has exactly the same properties as neon (atomic mass, for instance), but the closest to most of the same chemical and physical properties is probably argon, neon's next neighbor down in its periodic group 18.
What are the products of physical change?
The products of a physical change are the same as what you started out with because their have been no changes to its chemical properties. Ex: If you rip a piece of paper, it's still paper.
What is Radiant light energy?
This is part of the Electromagnetic radiation spectrum, visible light occupies a small part of this spectrum, but all wavelengths have the same physical properties
Does the iron in the mixture have the same or different properties to the element iron?
Iron keeps its unchanged chemical properties, but in a mixture it might add new, mostly physical properties to the alloy, this is also true for the other elements in the mixture, eg. C or Ni, or Cr in steel alloys.
Do compounds of the same functional group have same physical properties?
Elements with same functional group have same chemical properties. They possess different physical properties.
Why do iron filings do not sink when placed slowly on the surface of the water?
Surface tension supports the filings in the same way as a pond skater. Add a drop of detergent and the meniscus is broken down and the filings fall to the bottom
Does chemical and physical properties are probably the same?
No. Chemical and physical properties are different.
Is iron filings and sand a compound or an element?
compoundIf the iron fillings are pure, they contain only one type of atom (all the atoms have the same number of protons). Thus, the filings would be a sample of the element iron. If the filings are rusty, then they would contain compounds (iron oxides).
What is same in H2O and D2O?
The chemical properties are the same. The physical properties are not.
What do you need to know if you have two compounds of iron and chlorine to know they are the same compound?
Iron (II) chloride and iron (III) chloride have different physical properties: color, melting point, density, etc.
Can sieving method be used to separate iodine crystals and iron filling?
Highly doubtful - since you might get some crystals the same size as the iron filings. Your best method would be to use a magnet to remove the filings from the crystals.
What is a example of two items of different size having the same physical properties com?
For example two different (as size) nails made from the same iron alloy.
Is isotopes of same element have same properties?
The differences in chemical properties are not significant (excepting protium and deuterium); the physical properties are different.
What should be similarities among homologies?
Homologise have the different molecular masses so can not have the same physical properties, due to same functional group they show same chemical properties but with different rates of reaction.
Why can samples of gold and copper have the same set of physical properties but not the same set of chemical properties?
They do not have the same set of physical properties. At the very least they have different melting and boiling points, and different densities, and their colors are not identical.
