Is carbon steel an element'?
No, steel is a combination of Carbon and Iron. When referring to steel as "carbon steel" usually means the particular sample contains more carbon. This makes the steel harder but less flexible making it more liable to fracture.
At a certain temperature and pressure 0.02 mol of carbon dioxide has a volume of 3.1 L A 3.1 L sample of hydrogen at the same temperature and pressure?
contains the same number of molecules
How many carbon atoms are there in a 12.5 kg sample of carbon?
The answer is 6,2729.10e+26 carbon atoms.
Would a sample of the compound carbon dioxide in your school and another sample of carbon dioxide in Australia have the same composition and properties?
Yes they wouldn't have the same composition but not properties!
If a sample of copper contains 1.76E 4 atoms of copper-63 and 7.88E 3 atoms of copper-65 what is the percentage of copper-63 atoms in the sample?
add 1.78 x 104 and 7.88 x 103 together and divide by 1.76 x 104 69.315%
Which air sample contains the most carbon dioxide?

What A 70.00-g sample of an unknown compound contains 16.20 g of sulfur what is the percentage by mass of sulfur in the compound?
The percentage is 23,14 %.
A sample of table salt contains 1.967g of sodium and 3.033g of chlorine. what percentage of the sample is sodium?
3,033g + 1,967g = 5. (100/5) x 1,967 = 19,34%
Does silicon dioxide contain carbon?
Silicon dioxide contains only silicon and oxygen - no carbon., The only carbon in a sample labelled " silicon dioxide", would be an impurity or contaminant probably on the surface
Is carbon steel an element'?
No, steel is a combination of Carbon and Iron. When referring to steel as "carbon steel" usually means the particular sample contains more carbon. This makes the steel harder but less flexible making it more liable to fracture.
Does a small sample of Carbon-14 have the same activity as a large sample of Carbon-14?
No and yes. It depends on the way you define activity. Carbon-14 undergoes radioactive beta decay. The activity of Carbon-14 is given in terms of disintegrations per minute per gram of carbon. So, if you have a 100 gram sample and a 1 gram sample, there will be 100 times more disintegrations per minute with the larger sample. But typically, we are more interested in the time it takes a certain percentage to decay. Time values like half life will be the same for large and small samples.
A 76.00 g sample of unknown compound contains 12.90g of sulfur. what is the percentage by mass of sulfur in the compound?
