Sacramento tap water reveals ion concentrations of various different dissolved minerals such as calcium (Ca2+) and magnesium (Mg2+). These concentrations are a result of mineral deposits in local lakes and rivers. Perma Pure‚ a gas conditioning products manufacturing company‚ simplifies the mechanism of ion exchange by explaining that water is a solvent that dissolves most ionic bonds when exposed to compounds ("The Mechanism of Ion Exchange"). Therefore‚ as tap water passes through rocks it will

Arkansas is a unique state that has been divided into six regions: the Ozarks‚ the Ouachita Mountains‚ Crowley’s Ridge‚ the Arkansas River Valley‚ the West Gulf Coastal Plain‚ and the Mississippi Alluvial Plain. The six regions of Arkansas are all different in their own way‚ but they are what make our state beautiful. Each region has gone through good times and bad times which gives them a history. The six regions of Arkansas have a different economy‚ population‚ and topography. Today‚ I want to

Introduction Fresh water is an indispensable resource for human livelihood‚ agricultural irrigation and economic development (Brooks‚ 2007). However‚ due to the rapid population growth and the limited reserves‚ increasing regions have faced serious scarcity of fresh water (Williamson‚ 2010). Saudi Arabia is one of the driest countries in the world (CIA‚ 2011). According to World Bank (2011)‚ the world average fresh water consumption is nearly 7000m³/year/person‚ while the water resource per capita

Purpose: During our lab‚ Galileo’s Water Clock‚ we created our lab to describe the motion of a ball on a plane using the water clock as an alternative method for measuring time. Our main purpose in this lab was to determine if the displacement of the ball is determined by the time or the time squared. Procedure: Once the water clock was set up‚ a ball was let go from the ramp at various distances for three trials each. Once the ball was let go‚ the water clamp was opened and then immediately

Super Regions of the Philippines The "super" regions of the Philippines are an informal grouping of parts of regions and provinces of the Philippines based on their economic strengths. The creation of "super" regions was first proposed by the President Gloria Macapagal-Arroyo in her sixth State of the Nation Address to group the selected regions/provinces by their economic strengths.
