Water Shortage or Water Misuse The United States of America is known for her extreme overuse of everything. Americans see something they want and they simply take it. It was true when the young country pushed westward. The Native Americans were already there‚ but that mattered not; it was wanted‚ so it was taken. It is still true today. Americans as a people see what they want and they take it with very little regard to who had it first or where more might come from. Water is one of those

Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete. When the water freezes in the concrete‚ the pressure of frozen water increases

more harm than good. Here are three common myths about car batteries. Not Driving Your Car Much Means the Battery Is in Mint Condition While this may be true for some of your car parts‚ it isn’t for your car battery. If you only drive your car a few blocks down the road to the grocery store once a week‚ the battery will likely require more frequent replacements than your neighbor’s who drives hour-long daily work commutes.

AIM The aim of this investigation is to explore the effect of different concentrations of bile salts on the time taken for the lipase enzyme to break down fat. BILE Bile is a brownish bitter alkaline fluid produced by the liver and made by the hepatocytes from water‚ bile salts‚ bile pigments cholesterol and phospholipids and stored in the gall bladder. Bile is directly connected with digestion. It is released sporadically into the small intestine (duodenum) which is part of the gut in order

What is desalination? Desalination is the separation process of removing or reducing excess salts and other mineral from substances. 1 The process of desalination may be used on different substances however this paper will focus on the desalination of water. The desalination of water is very important to human and animal life. For centuries humans have used the process of desalination to obtain water safe for consumption.Various methods of desalination have been produced however only some of those
