What do you think would happen to the rubber if too many cross links were formed between the molecules?
If too many cross-links are formed between the rubber molecules, the material would become overly rigid and lose its elasticity. This excessive cross-linking can lead to a decrease in the rubber's ability to stretch and rebound, making it more brittle and less flexible. Ultimately, the rubber may become prone to cracking or breaking under stress, compromising its performance in various applications.

What do you think would happen to rubber if too many cross-links were formed between the molecules?
If too many cross-links are formed between rubber molecules, the material would become extremely rigid and lose its elasticity. This would result in a reduced ability to stretch and deform, making the rubber more brittle and prone to breaking under stress.
Is smoke formed from burning rubber a physical change?
Yes. Burning tires break down the rubber molecules into CO2 and other noxious gasses and other compounds are formed when the rubber lattice breaks into pieces as it oxidizes and burns.
Rubber is heated what happens to it's density?
When rubber is heated, it typically expands and its density decreases. This is because the increased thermal energy causes the rubber molecules to vibrate more, creating more space between them and leading to a decrease in density.
Why rubber is vulcanized?
Rubber is vulcanised to make it more stable and durable by adding sulphur at a high temperature. Vulcanization generates many sulfur-bond cross links between the rubber molecules, hardening the rubber and making it more elastic. Without these bonds rubber is a sticky gooey jelly like material.
How does heat affect the movement of molecules in a rubber?
Heat does not affect it. It expands with coolness. It contracts with heat.

Is a rubber hose a conductor or insulator?
A rubber hose is a insulator because of the space between the molecules.
What did rubber vulcanization do?
vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)
Why does rubber shrink when heated?
Rubber shrinks when heated because heat causes the rubber molecules to vibrate more rapidly, reducing the space between them. This increased vibration disrupts the material's internal structure, leading to contraction as the molecules move closer together.

Is rubber a polysaccharide?
No, rubber is not a polysaccharide..
Is smoke formed from burning rubber a physical change?
Yes. Burning tires break down the rubber molecules into CO2 and other noxious gasses and other compounds are formed when the rubber lattice breaks into pieces as it oxidizes and burns.
What happens to the molecules in a rubber band when tension is applied?
When tension is applied to a rubber band, the molecules in the rubber band are stretched apart, resulting in an increase in the overall length of the rubber band. This stretching occurs because the tension causes the molecules to pull away from each other, storing potential energy in the rubber band.
Why can a rubber band be compressed?
A rubber band can be compressed because its structure allows the rubber molecules to be pushed closer together when a force is applied. As the rubber band is stretched or compressed, the molecules rearrange themselves to accommodate the change in shape.
Is stretching a rubber a physical change or chemical change?
Stretching a rubber is a physical change because the rubber's molecules are simply being rearranged without any new substances being formed. Chemical changes involve the creation of new substances with different chemical properties.
Dose the temperature of a RUBBER bouncy ball effect the height of the bounce?
Yes it does. If the rubber is to cold the molecules in the rubber will not deflect "spring" allowing. If the rubber is to hot then those same molecules are to far apart to interact with each other in an optimal way.
What chemical and physical properties help rubber bands to be useful?
The molecules of polyisoprene present in rubber form in coils with a few links between coil levels. This allows the molecules to rotate freely around each other and return to their original shape. Think of it like a spring coil.
