be categorized into the bright line spectrum. Different elements give off different colors when heated because they all have different chemical properties‚ therefore‚ they will react differently under high temperatures. For example‚ [1] strontium‚ lithium carbonate‚ and strontium carbonate are often used in fireworks to create a red color. Calcium may be used to create orange‚ sodium for yellow‚ aluminum for white‚ barium chloride for green‚ copper for blue‚ strontium and copper for purple‚ and titanium

Why is a drug’s plasma half-life important to health care providers? Half life is important in determining the frequency of a drug administered in order to maintain a continuous drug effect. Identify 2 diseases/conditions that can increase the plasma half-life of a drug. It can be prolonged when liver or kidney disease is present. What could happen if a medication with a long half-life continues to be given to a patient with one of the diseases/conditions identified in above? Patients with hepatic

can implement a variety of refrigerants. Adsorption chillers use municipal water as the refrigerant and benign silica gel as the desiccant. Absorption chillers utilize water as the refrigerant and rely on the strong affinity between the water and a lithium bromide solution to achieve a refrigeration effect. Most often‚ pure water is chilled‚ but this water may also contain a percentage of glycol and/or corrosion inhibitors; other fluids such as thin oils can be chilled as well. Contents [hide] 1

Sanyo unsuccessfully sued BYD for patent infringement. BYD improved the quality of rechargeable lithium batteries. Unlike its major competitors‚ BYD’s battery products have never been recalled for safety problems. Although Sony currently controls the largest share of the consumer battery market‚ BYD is a major provider of batteries for many Motorola and Apple phones and electronics. Rechargeable lithium ion batteries contain more power than other batteries of comparable size. They are used in most
