Selective Precipitation of the Barium Magnesium Group ABSTRACT The purpose of this lab was to identify the cations from the barium magnesium group present in an assigned unknown solution through selective precipitation. This was a qualitative lab where the theory of the common ion effect was used in several steps. Once the experiment was completed‚ it was determined that unknown solution #4 contained Ba2+‚ Sr2+‚ and Mg2+ ions. INTRODUCTION Selective precipitation is a part of chemistry

Selective breeding (also called artificial selection) is the process by which humans breed other animals and plants for particular traits. Typically‚ strains that are selectively bred are domesticated‚ and the breeding is normally done by a professional breeder. Bred animals are known as breeds‚ while bred plants are known as varieties‚ cultigens‚ or cultivars. The cross of animals results in what is called a crossbreed‚ and crossbred plants are called hybrids. In animal breeding techniques such

Study Questions: 1.) Why is sub-soiling needed in soils with hard pans? Sub-soiling is essential especially to hard pan layer because it will help the roots penetrate deep and be able to explore and obtain water and nutrients from larger volume of soil. Hard span obstructs root’s downward proliferation and restricts root growth of crops (of crops that have vertical root growth). With sub-soiling‚ the needed soil depth‚ at least 80cm will be met . With sub-soiling‚ we can break hard pan without

Selective mutism (SM) is an anxiety disorder that prevents children speaking in certain social situations‚ such as school lessons or in public. However‚ they’re able to speak freely to close family and friends when nobody else is listening – for example‚ when they’re at home. It’s important to understand that when the mutism happens‚ the child is not voluntarily refusing to speak but is literally unable to speak‚ feeling frozen. In time‚ they learn to anticipate the situations that provoke mutism

Selective perception - it is a distance given to drive by car. Every person‚ who would do that‚ would notice different buildings‚ signs‚ posters and etc. We cannot notice everything‚ because our brain cannot receive that much information. So we concentrate on safe driving‚ and notice only those things‚ that we like: the dreamer will be looking at clouds perhaps‚ the advertising manager will be analysing new posters that competitors made‚ the old man will be looking at every road sign in order to

An intensive property is a bulk property‚ meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system. Examples of intensive properties are the temperature and the hardness of an object. No matter how small a diamond is cut‚ it maintains its intrinsic hardness. By contrast‚ an extensive property is one that is additive for independent‚ noninteracting subsystems.[1] The property is proportional to the amount of material in the
