Can Salt Harm the Environment? For many years, traffic due to road construction has been viewed as different. Driving to work or travelling from place to another with daily traffic due to road construction is becoming a challenge to all American people. The main task for highway engineers in winter is keeping the roads clear and safe from snow. Engineers are obliged to choose construction materials that are environment friendly and ecofriendly. For decades, engineers used the road salt deicing…

In this lab, the percent composition of each component in the mixture was calculated. The mixture contained NaCO, CaCO3, and sand. NaCO or salt had a physical change when it completely dissolved in water. A chemical change occurred when hydrochloric acid was added to CaCO3 or chalk because the mixture changed to a yellow green color. In order to obtain the percent composition, a filtration system was used to separate the sand from the liquid, by straining the solid with the use of filter paper.…

Salt use on roads in winter salt is a common way to clear slippery roads. Salt lowers the temperature of the water which causes it to melt and it's one of the effective way of lower weather related collision. Using salt on road lower car accidents on highway up to 80%. However, salt used on roads causes rust on cars and environmental studies had showed that salt use for de-icing could affect water supplies, soil,and wildlife. Negative effect of using road salt The more salt that gets into…

Introduction Brine shrimp are creatures that are known to thrive in harsher conditions, so they make an ideal research subject because of their durability. They are a native species of the Great Salt Lake, proving that they can withstand a high water salinity of up to 20 %+ ( https://microbewiki.kenyon.edu/index.php/Salt_Lake). Brine shrimp range from around 8-10 mm, including the tail. They have nineteen body segments, 11 of them include twenty-two legs total. Brine shrimp have an exoskeleton…

attracted to the oxygen (negative) end of the water molecules, and the negative Cl- ions were attracted to the hydrogen (positive) end of the water molecules. As an end result, the ionic bond between the sodium and the chloride was broken. CuSO4(s) ⇔ Cu+2(aq) + SO4-2(aq) Like the sodium chloride, the copper sulphate was split into its individual ionic components. The positive Cu+2 ions were attracted to the oxygen (negative) end of the water molecules, and the negative SO4-2 ions were…

Purpose The purpose of this lab is to investigate animal behaviors by diving into the world of ethology. There are two ways pill bugs will respond to environmental stimuli: Kinesis (non-directional response) and taxis (directional response). Kinesis occurs when organisms (randomly) move around quickly when they’re unhappy and slowly when they’re happy, which is best demonstrated when one lifts up a rock or other material that the pill bugs are under. In contrast to the simpler response that does…

2.1 Polydimethylsiloxane (PDMS) Polydimethylsiloxane (PDMS) own to a group of polymeric organosilicon compounds that are commonly stated as silicones. PDMS is optically clear, and, in general, non-flammable, non-toxic, and inert. PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid such as honey. However, at short flow times (or low temperatures), it acts like an elastic solid such as rubber. In other words, PDMS will flow to cover the…

Smoked Sea Bass Fish Ingredients required: 1. Sea bass – 4-5 lbs, skin-on fillets 2. Water – 1 quarter 3. Salt – 1 cup 4. White granulated sugar – 1 cup 5. Paprika – as per taste Instructions to follow: 1. Dissolve salt and sugar in the brine over a low heat. 2. Let the mixture set to cool. 3. Take Sea Bass, remove fillets and rinse under running water properly. 4. After rinsing, let the fish rest in brine and kept in fridge for at least 6-10 hours. 5. Preheat the smoker and add the wood…

In this modern world, plastic be the most used material for packaging in almost every industry. The word ‘plastic’ comes from the Greek plastikos which means easily shaped (Robertson, 2013). Plastic is the combination of many molecules that linked together as one long chain which made from polymers: poly (Greek) means many and meros (Greek) means part (Robertson, 2013). Raw materials of plastic are called feedstock which come from natural and synthetic resources, such as crude oil, natural gas,…

FT-IR analysis. Figure 1 shows infrared spectra of CNC, CNC treated with HCl and CNC treated with NaOH. This Data suggests that there are no significant changes in the structure of CNC due to extreme acid and basic media exposition. All the major vibration modes remained unchanged, this included 3330 cm-1 broad band corresponding to OH stretching, 2890 cm-1 due to CH2 and CH asymmetric and symmetric stretching, 1638 cm-1 related to the bending mode of absorbed water, 1430 to 1330 regions…
