(VCL) Introduction / Generic Lab Introduction Virtual ChemLab is a collection of realistic simulations. There are two general chemistry laboratories‚ including quantum and inorganic. The purpose of the quantum laboratory is to allow students to explore and better understand the foundational experiments that led to the development of quantum mechanics. In general‚ the laboratory consists of an optics table where a source‚ sample‚ modifier‚ and detector combination can be placed to perform

Organic food is defined as produce (animal and plant) that is grown without the aid of any chemicals or pesticides‚ this means the animals are fed organic feed and the plants are grown in a very different way to most foods we see at the supermarket. Many people purchase organic food because they think that the nutritional benefits will make up for the extra money that you spend. Lots of people say that the manufacturers of organic food lie to us when selling these products‚ they say that there aren’t

Naming Chemical Formulas Chemical Nomenclature There are over 19 million known chemical substances. Without some type of system‚ naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature. There are two major divisions to the International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen

Moreover‚ the continued dependence on synthetic commercial chemicals has led to the loss of fertility and productivity of the soil. Over the years‚ however‚ there has been an increase in the swing from conventional to organic agriculture. Organic agriculture‚ seen as a niche agriculture sector‚ is promoted as an effective and sustainable approach to food security‚ farmer’s profit instigation‚ and resource management. Aside from organic farming‚ the Department of Agriculture welcomed agricultural

eating organic foods and the main reasoning for this is because of the way these foods are grown. They are all grown on smaller farms and are cared more for. The farmers use natural soils‚ get rid of the weeds naturally without using sprays‚ and they use beneficially insects and birds to get rid of pests and diseases. Using natural resources to grow foods prevents us from eating chemical and in some cases added hormones. Organic foods have more zinc‚ iron and other vitamins than non-organic foods
