With the fiercely growing of the population and rapid expansion of city center, people had increasingly demand of water resource. In…

Key concepts Chemistry Chemical reaction Acids Bases Water Introduction Have you ever had a refreshing bath with bubbles or bath salts? What if you could use chemistry to create a bath-time treat that incorporated both fizzing bubbles and soothing salts? Such a combination does exist, and it's called a bath bomb. If you have never experienced one, these "bombs" become fizzy when they touch the water. Why? It is due to a chemical reaction taking place between different ingredients within the…

DNAPLs are chemicals denser than water, which do not typically dissolve into water. These toxic chemicals seep through the soil and find ways into groundwater depending on the physical chemistry of the substance(s). When the dense non-aqueous phase liquids (DNAPLs) have entered the groundwater they will continue to flow with it as a result of the hydrological cycle. There is no absolute way of knowing where the source of the DNAPLs is located, or if any bodies of water are contaminated even…

Glacial Melting – Cause, Effect, and Solution People and animals around the world need clean water year-round to drink and to use for growing crops and vegetation. Increased glacial melting is one casualty of global warming, which is caused by increased greenhouse gases like carbon dioxide, water vapor, methane, nitrous oxide, fluorinated gases, and ozone (EPA.gov, 2013;NASA, 2015), which tend to absorb infrared radiation (i.e. heat) that was emitted by the earth’s surface, which would have…

that water always seeks its own level. Plumbing systems are comprised of pipes, values, drains, fittings and fixtures. Most plumbing pipes are made of plastic PVC piping and sometimes galvanized steel. Plumbing systems are actually comprised of two separate, yet equally important subsystems. The first subsystem brings new water in and the second takes old water out. These systems supply water to fixtures, which are things like tubs, sinks, toilets and washing machines that draw in new water and…

How Many Drops of Water can a Penny Hold? Statement of the problem/purpose: The purpose of this experiment is to see how many drops of water a penny can hold. The point of this experiment is to teach the class about cohesion. Cohesion is the molecular force between particles within a body or substance that acts to unite them. Cohesion is in easier terms the bubble on top of the water you are pouring or the skin. It is like overflow without spilling over the side. Hypothesis: My hypothesis is…

these essential points and explain why they're so important. Swimming Pool Maintenance Success Tip #1: Water Circulation. Think of your pool as a big bucket of water. Without adequate circulation and water movement it quickly becomes a safe haven for bacteria and algae. Without proper circulation any chemicals added to the water essentially because meaningless. Anything you add to the water isn't circulated, which in turn, causes your free chlorine levels to quickly become depleted, your pH…

The United States of America should ban the practice of fracking. Although fracking has decreased the cost of natural gas in the country and would even provide over 600,000 new jobs which would decrease the unemployment rate, it is still not save for the American people. Yes, there are so many arguments that could be made in order to allow Oil and gas industries to engage in fracking, but what benefits would this be to people when most people end up dead? According to the scientific journal,…

In the past, the citizens of a teeming metropolis lived in their own filth, drank the cleanest water they could find, and subsided on whatever food was in surplus. This was just the way it was. Their poor living conditions were not due to any malicious force acting to subjugate them. Rather, their poor living conditions were due to a lack of understanding…

cornerstones of human cleanliness. Soap is, “a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added”( Soap 2018 ). Detergent is, “ a water-soluble cleansing agent that combines with impurities and dirt to make them more soluble and differs from soap in not forming a scum with the salts in hard water” ( Detergent 2018 ). Both soap and detergent are both…
