Vulcanization was first discovered by Charles Goodyear. ... The rubbers that are not undergone the process of vulcanization are called unvulcanized rubbers. The main difference between vulcanized and unvulcanized rubber is thatvulcanized rubber retracts to its original shape even after applying a large...
Oils with high demulsibility are generally preferred as water can compromise the lubricating properties of a product. This can lead to issues such as increased energy consumption due to resistance, surface corrosion and contamination caused by the release of abrasive wear particles....
the element 'oxygen' is part of the mixture 'air' and some of the properties of air are due to the oxygen part - but those properties are generally less strong / intense than those of pure oxygen because of the presence of the other constituents of the mixture called 'air', e.g. ...
What is the formula of nitrogen gas? What are the different forms of sulfur? What is the iron III sulfide formula? What are the chemical properties of sulfur? What is the formula for carbon monoxide? Given that the sulfur molecule has a mass of 32 amu, how many sulfur molecules are in...
Sulphur exists in two forms. What are they and what is one application of sulphur? Allotropic Forms: After carbon, sulphur is the element which possess highest number of allotropic forms. Sulphur is also able to show the phenomenon of polymorphism. ...
Rubber is a naturally occurring polymer, which is a linear polymer of isoprene. It can be easily deformed but regains its original shape after the stress is relieved. The properties of natural rubber can be modified and improved by process of vulcanization. It is mixed with 3 to5%sulphur and...
he Baobab - also known as “the tree of life” - produces fruits with incredible antioxidant properties. This helps stimulate the body to repair cell damage and neutralise the processes that lead to ageing. In addition, the fruits are rich in vitamin C, B-group vitamins, iron and fibre, ...
Step 2: Identify the Allotropic Forms of SulphurSulphur exhibits several allotropes, each with unique structures and properties. The main allotropic forms of sulphur are: 1. Rhombic Sulphur (α-sulphur): This is the most stable form of sulphur at room temperature. It crystallizes in a rhombic ...
Group IV base oils are polyalphaolefins. These are not extracted but made from small uniform molecules. This is also the biggest advantage of PAOs because they can be completely tailored to have a structure with predictable properties. They are very suitable for use in extreme cold or extreme...
Shallots arethe oldest home remedy for hair growth. They are rich in sulphur, which helps in the production of collagen tissues. This is useful for the regrowth of hair. ... Overall, shallots have a better nutritional profile than onions. ...
