Grey Water Shampoo-Chemical Characteristics

The procedure for this experiment is found in Stephen Thompson’s PSU Chemtrek on p. 10-15 through 10-22 under the “Chemistry of Natural Waters” lab. For the testing, four tap water samples were obtained from Virginia and State College, Pennsylvania—McDonald’s, the Atherton Hotel, and McKee Hall. Each member of the group proceeded through the testing methods in order to determine the hardness for a particular water sample. In accordance with the procedure, the AA technique was used first. Because the water sample from McKee Hall had no suspended particles, no filtration was required prior to testing; however, the sample was diluted with a 1:1 ratio.

Many unknown micro-contaminants are present in water. Some of the micro-contaminations might pose a risk to drinking water and human health. In many countries, surface water is one of the main sources of drinking water. The quality of the drinking water is influenced by many factors, such as agricultural and industrial waste, and is monitored regularly. Stated by the Journal of Chromatography, there are many techniques such as gas and liquid chromatography in order to detect the pollutants.

For the first sample from the sink there was high turbidity so that means there are dissolved or suspended particles like clay or algae in the water. This sample also had high conductivity so there was a high number of ions in the water. This can be caused by too many electrolytes dissolving in the water source. The sink water also had a low chlorine level. This can be caused by the chlorine reacting with other metals, organic and inorganic materials, or other compounds in the water before it is disinfected.

A rebel is the act of an individual refusing to listen or follow authority. Rebels are characters who fight for their own ideals. They will do anything almost being malevolent to destroy the limits set up against them. There are three characters that established themselves as “rebels”, from the short story unit. Captain Torres from “Just Lather and Nothing Else” , The group of children from “Green Gulch”, and Nick from ‘Let It Ride” are characters that refused to follow vital human morals.

The organization is required by the Drinking Water Operations or DWO to point out contaminants and tell consumers if the water they are using is safe. (2). Along with AWWA and DWO’s assessment, Houston, Texas has completed numerous, extensive studies of research and found that in 2014 the average number of Chloramine levels was at 2.2%, and the maximum number of Chloramine levels was at 4%. As for inorganic contaminants like Selenium or Arsenic, both were at levels less than average. Studies show that the Arsenic was considered low in this water supply, surely a relief to those drinking the water.

Hairspray is a romantic comedy film that came out in 1988. It was directed by John Waters. The movie takes place in 1962 in Baltimore and is about a self proclaimed young women called Tracy Turnblad. The story depicts both the rise of the teenager on a local TV to become a celebrity as a dancer and through her unpopular desire for racial integration. The story takes place at a time when the entertainment industry was greatly used to highlight the racial tensions and intercultural conflicts between the White and African-American that was taking place in the 1960’s.

These facts introduce and support the message that Standage is delivering. Standage continues with many statistics: “Admittedly, both kinds of water suffer from occasional contamination problems but tap water is more stringently monitored and tightly regulated than bottled water. New york city tap water, for example, was tested 430,600 times during 2004 alone.” He stated. Even though he admits that both of each kind contains chemicals-which at the same time Standage claims that the tap water is more sanitized-but also he points out that it is not the taste that differs between the two

Human beings have to make decisions that define who they are. The short story “Lather and Nothing Else” by Hernando Telléz is a story based on the Colombian revolution of the 1950’s in which this noble barber has to make decisions that will define his faith. The barber’s enemy, Captain Torres, comes to the barber’s shop to get a shave and with his enemy so close and a blade in his hand he had to decide whether he was going to kill Captain Torres. Would he become a murderer or would he keep being the professional humble barber he was? You might ask, what could’ve come between them to become such bad enemies?

Question One - Not killing (Pros and Cons) He believes that murder is wrong because he identifies as a “revolutionary” and in his opinion, this is quite different from being a murderer. “I am a revolutionary, not a murder” The barber realizes that murdering Captain Torres will create more problems than it would solve.

On the water quality reports, these values were overall different for each water company, so it was easy to narrow down the unknown sample’s identity by comparing numbers across all of these categories. The least helpful method was total dissolved solids because, when trying to distinguish between the two American companies, the ranges were very close and were not helpful in determining which company the water came from. Conclusion After completing an EDTA titration, atomic absorption spectrometry, and taking conductivity measurements, the calcium and magnesium concentrations, total dissolved solids, and total hardness of the unknown water samples were compared with known values from water quality reports in order to identify from which brand the sample came from. It was determined that sample A4 was from Poland Spring, B4 was from Deer Park, and D4 was from Evian.

Hairspray is a musical which stars a good natured overweight teenage who helps integrate the races in a popular teen dance show, the Corny Collins Show, in segregated Baltimore. It focusses on racism and segregation in the 60’s, but has the underlying theme of equality for everyone in spite of their race, class, sexual orientation, gender or outward appearance. Tracy Turnblad, an overweight teenager, finally gets a spot on the “Corny Collins Show”, a teen dance show she has always dreamt of being on. She is disturbed when she finds out the “Negroes” are allowed to dance on the show occasionally. She fights for integration despite being bullied and mocked.

Soap’s Effect on The Surface Tension Of Water By: Lusinda Garcia Biology I - Pre-AP December 10, 2017 Introduction Surface tension is when the surface of a liquid that’s in contact with gas, acts like a thin elastic sheet. Water has a high level of surface tension, which means that when the molecules on the surface of water are not surrounded by similar molecules on all sides, they're being pulled by cohesion from other similar molecules deep inside. These molecules bind to each other strongly but stick to the other mediums weakly. It has been proven many times that soap decreases water’s surface tension; however, there is still a vast amount of people that believe soap increases the elasticity of water’s surface tension. Soap’s negative

This means that 25 to 40 percent of the bottled water is not any different from the tap water only that it has been exposed to or has a high concentration of the chemicals used to manufacture the packaging plastics. Due to the pathetically primitive regulation of the bottled water, the manufacturers are not keen to inform the consumers of the contaminants that are present in their water. According to Warburton (1993), consumers are likely to drink bottled water containing contaminants such as E.coli, asbestos, giardia, bromate and many other industrial chemicals and pathogens. Arnold & Larsen (2006) indicate that ten water brands in the US had thirty-eight

Hair Moisture content basics One of the issues that bothers many is dry hair. When the hair is dry, it is not soft to the touch, and it looks and feels like a straw. Also, compared to normal hair, dry hair will not look healthy, and it won’t have natural shine. Importance of moisture When it comes to hair, it may become dry in the same way the skin can. The most important thing is to provide moisture to your hair, because when it is dry, it means it has the lack of moisture.
