Sulfur is used to cross-link the rubber. This means that the sulfur forms 'bridges' between the long chained rubber molecules. This serves to tie the molecules together, making the material harder. Think of an eraser used to correct pencil writing. That is very soft rubber. Vulcanisation turns that into the much harder material we use for car tyres. If you know anything about motor racing you will be aware that they use tyres of different hardnesses, and this is achieved by different amounts of cross-linking. If you use a lot of sulfur you can even make a rigid material known as ebonite, which is what Musical Instruments such as clarinets are often made of.

What is the chemical name of H2Se aq?
hydrosulfic acid (this is not correct) It is hydrosulfuric acid (All acids containing sulfur or a sulfur-containing group, use the whole word "sulfur" rather than the stem "sulf").
how many grams are in 0.155 mole of sulfur?
To find the mass of sulfur in grams from moles, you can use the molar mass of sulfur, which is approximately 32.07 grams per mole. For 0.155 moles of sulfur, you multiply the number of moles by the molar mass: 0.155 moles × 32.07 g/mole = 4.97 grams. Therefore, there are approximately 4.97 grams of sulfur in 0.155 moles.
In green and purple bacteria electrons to reduce CO2 come from?
H2S Green and purple bacteria carry out anoxygenic photosynthesis, using reduced molecules other than water, as an electron source for the generation of NADH and NADPH - Purple sulfur bacteria use reduced sulfur compounds as electron sources and accumulate sulfur granules within their cell - Green sulfur bacteria use reduced sulfur compounds as electron sources and deposit sulfur granules outside their cell - Purple nonsulfur bacteria use organics molecules as their electron sourcec
How many kinds of atoms are in sulfur dioxide?
One if it is pure sulfur. Sulfur is an element so the on atom is sulfur!
If 5.58 g of iron react with sulfur to produce 8.79 g of iron sulfide what is the mass of reacting sulfur?
To find the mass of reacting sulfur, we can use the law of conservation of mass, which states that the mass of the reactants equals the mass of the products. Here, the mass of iron sulfide produced (8.79 g) is the sum of the mass of iron (5.58 g) and the mass of sulfur. Thus, the mass of sulfur can be calculated as: Mass of sulfur = Mass of iron sulfide - Mass of iron Mass of sulfur = 8.79 g - 5.58 g = 3.21 g. Therefore, the mass of reacting sulfur is 3.21 g.
What element is used in Vulcanisation?
Sulfur.
What is the formation of synthetic rubber by cross linking with sulfur?
Vulcanisation
What is the non metal used in vulcanisation of rubber?
Sulfur is the non metal used in the vulcanization of rubber. When heated with rubber, sulfur forms cross-links between the polymer chains, improving the rubber's strength, elasticity, and durability.
What did vulcanization do?
vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)

When was the vulcanisation of rubber made?
i have no idea at all that is why i typed it in
What process involves treating rubber to harden it?
Vulcanisation.
How is rubber made tougher?
Vulcanisation- addition of sulphur
The process of curring rubber named after the Roman god of fire?
Vulcanisation
What could you use to separate sulfur and iron?
You can use a magnet to separate iron from sulfur since iron is magnetic while sulfur is not. By using the magnet to attract the iron particles, you can separate them from the sulfur.
Explain how to separate sulfur and iron filings?
Use a magnet to extract the iron from the sulfur.
Why was vulcanization important?
rubber was not very useful until vulcanisation was discovered . this process can improve its elasticity and strength .
