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…

and 2-nitrophenol the difference in slope or degradation rates for chloride and sulfate are 0.71 and 0.55, and only 0.16 for 2-chlorophenol. The presence of chloride inhibits in greater proportion the formation of hydroxyl radicals than the sulfate , this can be due to some free radicals that are scavenged and the formation of some chlorinated inorganic radicals like Cl•, HClOH•/ClOH•-, Cl2 ・-) The difference between the chloride and sulfate are for few reasons. First, the sulfates radicals are…

trials were low due to the errors that occurred throughout the lab. Another topic that relate to this lab was single replacement. In this experiment, solid magnesium and hydrochloric acid solution underwent a single replacement that yielded magnesium chloride and hydrogen gas. Additionally, the ideal gas law was used in this experiment to find the moles of hydrogen gas. Another topic that relate to this lab was the limiting reagent. The limiting reagent in this experiment was the magnesium.…

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…

Conductivity of Salt Water/ Salt Water Circuit Introduction to Physics UBT 1- Task #2 19/11/2015 Western Governors University Thiago Predebon Introduction: Saltwater Circuit; Did you know that you can use salt water to make a light bulb shine? It sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an…

Chemistry Internal Assessment Introduction: The experiment is to conclude which aqueous solution of the chlorides has the highest boiling point out of the five that has been tested.there will be five different chloride compounds mixed into water and be heated till it is boiling. The interest for this topic comes from how intermolecular forces affect the molecules by either repulsing and attracting molecules due to polarity. This idea interests me because when cooking and boiling salt water,…

between the Calcium Chloride and phenol red are responsible for the high temperature change in the overall reaction. After doing a control experiment with Sodium Bicarbonate and phenol red and noticing that the temperature got colder, only one other chemical mixed with phenol red could be responsible for the warm temperature change that chemical being Calcium Chloride. There was a temperature change that was observed during the individual control labs as seen when calcium chloride was mixed with…

1.1 Overview: In a research lab, Mr. Z trying to formulate a colloidal dispersion system with sodium lauryl sulphate. What type of colloidal system is suitable for sodium laurly sulphate and also we have to discuss the different stability factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it…

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…
