Which has the most oxygen atoms?
Ernest Z. Truong-Son N. The biggest amount of oxygen is in 5,06×10-3 mol.
Which is the minimum number of atoms of oxygen?
Number of V2O5 molecules= (0.1×Avogadro’s number) molecules. =1.5×1023molecules. Considering option D. Hence, the minimum number of oxygen atoms are present in 10ml of H2O molecules.

What are the three common forms of carbon?
Different forms, or allotropes, of carbon are diamond, graphite, and fullerenes. In diamond, each carbon atom is bonded to four other carbon atoms, forming a rigid structure that makes diamond very hard.
Are Diamonds compressed coal?
Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. In fact, most diamonds that have been dated are much older than Earth’s first land plants – the source material of coal!
Is carbon bad for lungs?
The most likely effect of exposure to carbon black is lung disease. Inhaling carbon black particles can irritate the lungs and cause coughing. Carbon black can also irritate the eyes, nose and throat. When people are exposed to high levels of carbon black over many years, the particles may lodge deep in their lungs.
What is Carbon Black good as?
Carbon Black is the most widely used and cost-effective rubber reinforcing agent (typically called Rubber Carbon Black) in tire components (such as treads, sidewalls and inner liners), in mechanical rub- ber goods (“MRG”), including industrial rubber goods, membrane roofing, automotive rubber parts (such as sealing …
What is black carbon used for?
Carbon black is mainly used to strengthen rubber in tires, but can also act as a pigment, UV stabilizer, and conductive or insulating agent in a variety of rubber, plastic, ink and coating applications.
Why is carbon black in rubber?
Almost all rubber compounds use carbon black (CB) as a filler. Carbon black filler functions to strengthen, increase the volume, improve the physical properties of rubber, and strengthen vulcanization. The results of the rubber compound can be useful in making shoe soles, gloves, and motorized vehicle tires.
