The Hard Way

Discussion: In this section the results of the degree of water hardness of the water samples of this group using the two primary methods EDTA and AA will be discussed and analyzed in terms of which sample is exhibiting a high degree of hardness and which sample is considered to have a small water hardness value compared to other samples, and test the hypothesis and prediction of the water samples being tested. According to the results obtained and calculated the water sample that has a high…

presence of divalent cations dissolved in a water sample. The divalent cations usually present are Ca2+ & Mg2+ and these cations bestow chemical properties to water. Thus, hard water will have increased concentration of divalent cations when compared to soft water. Ca2+ & Mg2+ are the most commonly found divalent cations in hard water and are denoted by a +2 charge. But, polyvalent cations…

Composers are no longer only middle aged, white men who play violin, piano and write music by hand. In today’s time, composers are producers who create music through their computer such as Pharrell Williams and Erick Arc Elliot of the Flatbush Zombies. Both of these producers repeatedly create some of the best music ever produced, and will only get better with time. The work of Pharrell is more popular than that of Erick Arc Elliot due to Pharrell’s time spent in the music industry and his…

In the locker room are Dan and Jason. I say hello and continue on to my locker. More people come in and everyone starts talking about how bad their day was. It's almost a daily contest to see who can have bragging rights for having the worst day, perhaps they want sympathy or maybe they just like to complain a lot. I find it humorous that a bunch of guys who come in every day to train and beat on each other can complain so much, so I laugh at them and leave the locker room. I start…

Introduction The definition of water hardness, in its simplest form, can be explained as, “the amount of dissolved calcium and magnesium in water.” Water hardness can be attributed to groundwater systems naturally flowing through soil and rock. While doing so, divalent amounts of cations from mineral sources dissolve into the water supply (USGS). Water hardness is not harmful to people’s health. In fact, these minerals can be beneficial, as humans need minerals to survive. However, water…

It was that time on a particular Wednesday, more specifically 2:30 pm to 4:20 pm; I sat in the lecture room at HKU preparing myself to pay full attention to Dr. Giorgio’s lecture. He stood in front of 200+ students and lectured us about “Seeing music”. As the lecture progressed to the topic about sexuality and music, he projected a YouTube video featuring the famous guitarist of the 1970s, Jimi Hendrix. The video was recorded at Miami in 1968, where Hendrix is performed one of his best-known…

The Red Hot Chili Peppers are one of my favorite bands of all time. Have you ever heard a song on the radio before and wanted to hear it again? That’s what happened to me and it turned into a lifetime of listening. When I was young around the age of 8 or 9 I heard some songs on the radio called Dani California and Snow (Hey Oh). When I was young I didn’t know how to find songs unless the person on the radio said the songs name. Both times I had missed the names so I was shit out of luck but…

Zinc is an important dietary component in human beings and animals. Although not considered hazardous, overdose of Zinc may cause nausea, vomiting, dizziness, colics, fevers and diarrhea and if it exceeds a certain limit it may also prove to be toxic. Zinc, present in natural water in small concentration, most commonly enters the domestic water supply from deterioration of galvanized iron and dezincification of brass[1,2]. Industrial and household waste, discharges directly or indirectly through…

together, and the two discuss that each of them want to change their social status: Jean wants to build his status while Julie wishes to fall lower on the status pole. Julie explains, “I find myself seated at the top of a high pillar and I see no possible way to get down. I grow dizzy when I look down, but down I must. But I'm not brave enough to throw myself… And yet I can find no rest or peace until I shall come down to earth; and if I came down to earth I would wish myself down in the ground”…

lineup; guitarist and backup vocalist Keith Wallen, bassist and backup vocalist Aaron Bruch, guitarist Jasen Rauch, and drummer Shaun Foist. The band then released a new album, “Dark Before Dawn”, in 2015. Breaking Benjamin’s musical style is primarily hard rock, with some post grunge and alternative metal influences. The…
