impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid. 3. What effects on the measured melting

These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint

educator Friedrich Froebel designed‚ the organic unity of a Japanese building Wright saw at the Columbian Exposition in Chicago in 1893‚ and a Jeffersonian belief in individualism and populism. Always a believer in architecture as "natural" and "organic‚" Wright saw it as serving free individuals who have the right to move within a "free" space‚ envisioned as a nonsymmetrical design interacting spatially with its natural surroundings. He sought to develop an organic unity of planning‚ structure‚ materials
