Identification of a Hydrate Based on Percent Water Varun Wadhwa 11/19/12 Introduction The identity of an unknown hydrate was determined by massing the hydrate before and after heating and calculating the percentage of water. Procedure First‚ we cleaned‚ dried and heated an evaporating dish for five minutes on an iron ring with the Bunsen burner and massed it. Then‚ we added 2 grams of an unknown hydrate and calculated the mass of that. Next‚ we used gradually increasing heat for

Word formation From Wikipedia‚ the free encyclopedia In linguistics‚ word formation is the creation of a new word. Word formation is sometimes contrasted with semantic change‚ which is a change in a single word’s meaning. The boundary between word formation and semantic change can be difficult to define: a new use of an old word can be seen as a new word derived from an old one and identical to it in form (see conversion). Word formation can also be contrasted with the formation of idiomatic expressions

The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However‚ the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system’s gravity‚ so star formation only occurs in a few areas. The

The formation of ASEAN was mainly driven by the desire to improve on diplomatic relations between Southeast Asian nations so that they could focus more on nation building efforts. The 1960s was the decade of tumult‚ where Southeast Asian nations faced various external tensions and conflicts from one another. During then‚ it was of utmost importance for SEA nations to improve multilateral diplomatic relations so as to promote peace in the region. This peace would refer to ensuring political stability

of an Unknown Hydrate The purpose of the Formula of an Unknown Hydrate lab is to determine the weight percentage of H2O hydrated to an unknown salt and the empirical formula for the hydrated salt. To do this‚ a massed amount of the hydrate is heated over either a hot plate or Bunsen burner. This causes the water to be removed‚ leaving the anhydrous salt behind in the dish. The mass of the anhydrous salt‚ now with the absence of water‚ is less than the original mass of the hydrate. The difference

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil
