Conversely‚ achievements in chemistry have been converging into the nanometre range from below – from atoms and molecules to supramolecular chemistry. Nanochemisty focuses on the unique properties of materials in the 1–100 nm scale. The physical‚ chemical‚ electrical‚ optical and magnetic properties of these materialsare all significantly

Chemistry is the science of dealing with the compounds‚ elements‚ and molecular structure of matter. Essentially‚ chemistry is the science of examining substances and objects to find out what they’re made of and how the react to different conditions.

The Inorganic Chemistry of Carbon Inorganic Carbon For more than 200 years‚ chemists have divided compounds into two categories. Those that were isolated from plants or animals were called organic‚ while those extracted from ores and minerals were inorganic. Organic chemistry is often defined as the chemistry of carbon. But this definition would include calcium carbonate (CaCO3) and graphite‚ which more closely resemble inorganic compounds. We will therefore define organic chemistry as the study

Plastic bags are not biodegradable‚ so they get littered onto a wasteland which causes soil erosion causing damage and harm to the trees. If plastic bags are burnt‚ they emit hazardous gases causing air pollution which causes damage on the ozone layer. The Plastic can be reduced by u not using lots of plastic and use things in yr homes then going to buy a plastic bottle from the shop. Plastic bags are made out of non-biodegradable substance.(not organic)Because they are durable they do not

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

Air pollution – contaminants or substances in the air that interfere with human health or produce other harmful environmental effects. Read our “What is Air Pollution?” article for further information. Alternative energy – usually environmentally friendly‚ this is energy from uncommon sources such as wind power or solar energy‚ not fossil fuels. Alternative fuels – similar to above. Not petrol or diesel but different transportation fuels like natural gas‚ methanol‚ bio fuels and electricity. B

Plastics Bags- A Devil To Be Banned Plastic bags are normally given to customers by vendors when buying. It is a very convenient method for transporting goods. Moreover‚ it is highly popular to the customers and retailers because of its light weight. But‚ ultimately this much usage of the plastic bags leads to the many serious problems. Plastic bags should be banned in Canada because it have a critical environment problems‚ health problems and also because of its cost of production and recycling

disputed is the idea of banning plastic bags. As people become more aware of the environment and are attempting help‚ the environment they come up with more ways to. The most known way to help the environment is to reuse and recycle; however‚ many want to go even further than that and ban certain items. There is a recent argument on both a local and global level on the issue of banning plastic bags. There are grocery stores that have already banned plastic bags and there are stores that are debating
