How do you distinguish between nitrogen oxide and oxygen using a chemical test?
Use a sample of pyrogallol (C6H6O6) in the sample followed by a combustion reaction. This compound absorbs oxygen present.
How is a sample oxygen different from a sample of a water?
Oxygen is just O and water is H2O
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
The mass of silicon is 4 659 g.
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!
When a sample of germanium and silicon having same impurity density are kept at room temperature then resistivity of both?
Resistivity of silicon higher than that of germanium
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
What is a sample of SiO2?
silicon dioxide
Why silicon dioxide cannot be the only compound in the sample of sand?
sand is a mixture, not a compound.. silicon dioxide is just a compound

How many grams of carbon dioxide are present in a sample containing 80.0 moles of CO2?
80,0 moles of CO2is equal to 3 520,8 g.
What is the concentration of carbon dioxide in this sample?
well when the heart pumps then its the sample
What state was argon found in?
Argon was found in the gaseous state. A sample of clean air was taken. Then oxygen, carbon dioxide, water, and nitrogen were removed. One unknown gas was still in the sample. This was later determined to be Argon.
How many grams of silicon would there be in a sample that contained 9.99 x 1025 atoms?
The mass of silicon is 4 659 g.
What is the mass of a 350 cm3 sample of pure silicon with a density of?
2g/cm3
What is mean chemical oxygen demand-?
The mean oxygen demand is the test done to indirectly determine the amount of organic compounds present in a water sample.
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!
