"Charcoal" is an ancient Chinese character. It was first seen in the Han Dynasty's "Shuo Wen Jie Zi". The character "carbon" appeared in China in the 1930s with the development of modern natural sciences, especially the discovery and advancement of chemical elements. It is named after the...
No exact definition of an "organic" substance has been agreed upon by the chemical community and textbook definitions vary substantially. The question of what exactly constitutes an "organic" substance is explored in this paper. Various carbon-containing substances that have been by some considered ...
They are identical chemically – both are composed of carbon (C), but physically, they are very different. ... Graphite is very soft and has a hardness of 1 to 2 on this scale. Diamonds are the hardest known natural substance and have a hardness of 10. What is versatility example?
In alcoholic fermentation, two sequential reactions produce carbon dioxide and ethanol as end products. In lactic acid fermentation, pyruvate is reduced to lactate in a single reaction that also oxidizes NADH to NAD+.Answer and Explanation:
Seaweed is a sustainable packaging solution made from agar – a gelatinous substance found in many seaweeds and algae. The agar is extracted and dehydrated to produce a material appropriate for packaging. Being made from a plentiful, sustainable raw material, seaweed packagi...
Allotrope of carbon with a layered structure. Elemental chemical substance (symbol C, atomic number 6). 13 Hardness Soft, used in pencils. Varies; can be very hard as diamond. 13 Electrical Conductivity Good conductor due to delocalized electrons. Conductivity varies by allotrope; diamond is an ...
Diamond is an allotrope of carbon, same substance with different atom configuration. Atoms in diamond form a strong bond in the shape of tetrahedron, resulting in a very strong substance. Graphite is another allotrope of carbon, but atoms are bonded in a different way, it is more of a plana...
Carbonization isthe conversion of organic matters like plants and dead animal remains into carbon through destructive distillation. What is Calorific Value Class 8? “Calorific value refers tothe quantity of heat produced by complete combustion of a unit volume of a substance.” The amount of heat...
It goes out. Carbon dioxide is already in the energetically most stable state; it will not support combustion of the splint. Carbon dioxide is a good..
What is Carbon Monoxide Unlike CO2, carbon monoxide only has one oxygen atom and one carbon atom. CO does not occur naturally in the environment and is a man-made substance. Carbon monoxide is pumped into most modern homes and used for all sorts of items, such as dryers, heaters, fireplac...
