LDPE (low density polyethylene) is used for making plastic bags because it is appropriate and HDPE (High density.....) is not.
Atoms are bonded in ionic crystals.
The polymer "polythene".
Polythene or more correctly named polyethene is a compound of ethene that has undergone addition polymerisation. So yes, it is a compound. An acid is a compound that can donate protons (H+) A element is a 'pure' form that contains just the element it's self. They are all listed on the periodic table A compound is a substance made up of different elements that are all chemicaly bonded together. (By either ionic or covalent bonds) A mixture is a 'mix' of different compounds or elements that are not bonded together.
No, polythene does not dissolve in water as it is a non-polar polymer and water is a polar solvent. This lack of attraction between the polythene molecules and water molecules prevents it from dissolving.
The main difference between Ordinary Polythene & Biodegradable polythene is: * Ordinary polythene takes an around 100 + years to degrade... * Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms...

They are tightly bonded together therefore they can only vibrate.

Polythene.
The polymer "polythene".
Polyethene (polythene, polyethylene) is a chemical product.
Polythene - album - was created in 1996.
This is because on a molecular level, gases and liquids are unorganized. In solids, which do not flow, molecules are bonded together in organized, lattice structures.
When polythene is rubbed with a cloth, electrons are transferred from the cloth to the polythene, causing the polythene to become negatively charged. This transfer of electrons creates an imbalance of charges between the two materials, resulting in the polythene having a negative charge.
hazards of polythene bags
When polythene is rubbed with wool, electrons are transferred from the wool to the polythene due to differences in their electronegativities. The polythene gains extra electrons, making it negatively charged, while the wool becomes positively charged due to losing electrons.
Yes polythene can be used to make clothes
