that measures the quality of water for its household and industrial users. Water’s hardness arises from the presence of metal ions – specifically metal ions with a charge of +2 or higher. The ‘scum’ left over in a cleaned shower stall or coffee pot is equivalent to water hardness. Water dissolves salts which contains ions of sodium‚ magnesium‚ calcium‚ iron‚ and many other metal; however‚ the most prevalent ion found is calcium. Since calcium ions typically make the most predominant contribution to

Sacrifices Summary and Characterization The story Sacrifices by R.J Ellory is about Kathleen Reynolds who works as a cop at the Fairfax County Homocide Division. Kathleen Reynolds has given up both husband‚ kids‚ her family and holidays‚ for her career. Later on in the text we are introduced to a woman named Bitsy whose mother is diagnosed with terminal cancer. Bitsy can’t bear seeing her mother in agony‚ and therefore she overdoses the morphine that is used to relieve her mother’s pain‚ with the

smooth pipe shows that there are existence of laminar and transitional flows as stated in Graph 2.0 and Graph 2.1. It is proven that the higher velocity along the smooth bore pipe‚ the higher is the head loss of water. As shown in Table 3.0‚ when the Reynolds’ number increases‚ the value of pipe coefficient friction‚ f decreases along the decreasing stead laminar line. On top of that‚ there are energy loss from the water to the surface of the pipe and therefore‚ the temperature increases when velocity

quantities in ore minerals such as monazite and bastnasite. Neodymium is located in the sixth period and is a part of the Lanthanide family. Neodymium is a chemical element with the symbol Nd‚ the atomic number 60‚ and a soft‚ bright‚ silvery white metal. It was first identified in 1885‚ in Vienna‚ by Austrian scientist Carl Auer von Welsbach. Neodymium was discovered in ‘didymium’ a substance incorrectly identified by Carl Mosander in 1841. In 1869‚ ‘didymium’ had the symbol Di in Mendeleev’s first

Repeat step 1 for each of the unknown metals and predict the identity of the unknown metals. Repeat any of the known metals to help with this prediction.

Silver is a beautiful‚ soft‚ white‚ lustrous metal thats strong‚ malleable and ductile. It is because of this materials softness that it must be alloyed with base metals like copper‚ as in the case of sterling silver (92.5% silver‚ 7.5% copper).
