Polythene can be used to modify reaction conditions by providing a controlled environment, such as enhancing the reaction's temperature stability or preventing moisture exposure. Its chemical inertness allows it to be employed in various reactions without participating or interfering. Additionally, polythene's insulating properties can be utilized to maintain specific temperatures, aiding in reactions that require thermal regulation.
What else can I help you with?
Why you do not use polythene?
We avoid using polythene because it is a synthetic material that is not biodegradable and can contribute to environmental pollution. As a more eco-friendly alternative, we opt for materials that are biodegradable, compostable, or recyclable to reduce our impact on the environment.
What is the benefit of using polythene to wrap food?
Polythene wrapping offers several benefits for food preservation, including protection against moisture, contamination, and spoilage. Its impermeable nature helps to extend the shelf life of perishable items by reducing exposure to air and bacteria. Additionally, polythene is lightweight and flexible, making it convenient for both packaging and storage. Its transparency allows for easy visibility of the contents, aiding in inventory management.
What is the only thing that can get changed in a balancing equation?
It is the mass defect during a fission reaction. Enrgy evolved during a radioactive fission can be calculated using the formula gived by Einstein e =mc
What is the name for the condition that is manipulated by scientists?
The condition that is manipulated by scientists in an experiment is called the independent variable. It is the variable that researchers intentionally change to observe its effect on the dependent variable.
What is the definition of catalysis?
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
What is changed in the original substance during a chemical reaction?
It all depends on what chemicals you are using. For example, if you were using sulfur & carbon, either one could be changed.
What can you do as a group to stop water pollution?
to stop using polythene's

How can you control the use of plastic?
we can control the use of plastics by using paper bags instead of polythene bags, by recycling some plastics and using renewable resources.
How is polyethlene made?
It is made by a process called polymerization, this is where they take lots of monomers (in this case ethene) and combine them together using an addition reaction. This is only possible in monomer where there is a double bond as to add them the double bond has to break for there to be enough room on the carbon for the new monomer. This process is done millions of times and is finally makes polythene which is used to make bin liners and poly bags. This is the proses: Crude Oil -> Crude Oil Vapour --> Diesel Oil --> Ethene --> Polythene

What are the disadvantages of polythene?
Disadvantage is that polythene once made cant be destroyed ever............polythene is big terror to our environment also Polythene is not biodegradable, and if dumped in the soil causes harm to the plant life, as the toxic substances of polythene get blocked among the soil particles. . Polythene threatens the life in the water bodies. The chemicals in polythene affects the survival of flora and fauna of the aquatic and marine eco systems. . Polythene is also likele to clog the drains causing problems in the water flow of the pipes. The pipe blockages would cause flooding and the free flow of water is disturbed. . Polythene is harmful for animals if swallowed. It solidifies inside the abdominal cavitywhich ultimately becomes lethal to the animal. . In most households poly bags are used to preserve food items. It has been found out, the colourful poly bags contains lead and cadmium which are toxic and causeadverse effects to human health. . If polythene is burnt in open air Hydrogen cyanide which is carcinogenic (cancer causing) is released. Hydrogen cyanide causes environmental pollution and health hazards
Why is your face is burning and peeling after you changed your face wash?
You're probably having a reaction to something in the new face wash that you are using. Rinse your face with clean, warm water and then stop using that certain face wash.

Can you put polythene in microwave?
No, you should not put polythene (plastic) in the microwave unless it is specifically labeled as microwave-safe. Non-microwave-safe plastics can melt, warp, or release harmful chemicals when heated. Always check the packaging for microwave safety guidelines before using any plastic in the microwave.
At which temperature would a reaction with H -92 kJmol S -0.199 kJ(molK) be spontaneous?
The condition for a reaction to be spontaneous is ΔG < 0, where ΔG = ΔH - TΔS. At the temperature where ΔG becomes negative, the reaction will be spontaneous. You can calculate this temperature using the given values of ΔH and ΔS.
What are the advantages and disadvantages of using polythene to control weeds?
Using polythene to control weeds offers several advantages, including effective suppression of weed growth by blocking sunlight and reducing competition for nutrients and moisture. It also helps retain soil moisture and can enhance soil temperature, promoting crop growth. However, disadvantages include potential environmental impacts from plastic waste, as polythene can take a long time to decompose. Additionally, it may hinder soil health by preventing natural processes, such as aeration and the movement of beneficial organisms.
