Neon signs, you can find them just about anywhere such as bars, bowling alleys, and restaurants. You mainly see them in store windows saying “open.” But “open” signs are just the beginning. You can find them in a variety of vibrant colors and complex shapes. The atoms of the 18 noble gases including neon and argon, etc, will almost never form stable molecules by chemically bonding with other atoms. It’s simple to build a gas discharge tube such as a neon light which reveals that inertness is a

During this experiment, we will be able to see the effects of natural pollutants on Ankistrodesmus allege. so that there is an incredible amount of pollutions in the world, the almost infinite amounts of experiments that can be used to test these theory’s and hypothesis. The one that our group used was the allege and sodium chloride method to test the effects of pollutiants. We gave this experiment 21 days and recorded they data every day we attend the class for non-consecutive three weeks. In this

The quality of lakes around the world are slowly being decreased, due to factors such as pollution, littering, not enough exposure to sunlight, and generally a clack of biotic factors. This is why it is important to assess the health of lakes around the area and analyse if the lake is habitable and healthy. The lake that will be assessed is Lakewood Lake, located in the Brisbane area near Lakewood. The health of Lakewood Lake is in question as biotic and abiotic factors will be tested to assess the

The purpose of doing a lab based on endothermic and exothermic reaction is to tell which is an endothermic reaction or which is an exothermic reaction like baking soda and calcium chloride. The lab setup for this lab are, five grams of baking soda, five grams of calcium chloride, one plastic bag, 30 ml of water, a 50 ml beaker, a rubber band, and two thermometers. During the experiment we found out about all the responding variables we had. For example, calcium chloride and water responded together

Different authors have different styles just as humans express the way we feel by the clothes we dress in or the items we put on our bodies. Styles of types of writing are diction, syntax, and imagery. One author that can easily express his style with these ways is the author Robert Fulghum. In his short story “Dinner Dandruff” his style is expressed greatly by stating his point of views on a serious tone but adding just enough humour. Robert shows his style through diction by instead of stating

amphiphiles such as fatty acids, fatty alcohol, and monoglycerides also have the inherent ability to coalesce because of their bipolar nature and were confirmed to be existent by the Murchison meteorite. Monocarboxylic acids were found in excess on the meteorite and the physical properties of the vesicles they form were studied. The length and degree of unsaturation of the hydrocarbon chain affects vesicle permeability and stability properties.

This source focuses on the condition that the flower should be in when it is inserted into the vase. This source also opposes other sources in that it states that flower stems should cut 5 cm above the bottom at an angle in lukewarm water instead of cold water. The source also states that flowers should be kept out of direct sunlight and away from fruits as they omit a gas that causes the flowers to wilt faster. The method proposed by this source is the following: Add 60 ml of Listerine mouthwash

1.4.1 Discovery and abundance of homoacetogens Homoacetogens are strict anaerobic bacteria that produce acetate from CO2 as a diagnostic end-product of metabolism (Drake 1994, Muller 2003). They can grow on different substrates such as hydrogen, hexoses, formate, carbon monoxide, methoxylated compounds, and alcohols. Depending on what energy sources they are growing with, products in addition to acetate can be formed, and some can produce butyrate from CO2 using the same basic pathway as used for

With both mines worked for Pb and Zn, naturally, these two elements are found amongst the key metals of contamination and toxicity to organics found on the site. Lead is released into the wider environment in the form of elemental Pb, oxides and hydroxides along with oxyanion complexes. Normally, it occurs with an oxidation state of 0 or +II. Pb(II) is more common than its uncharged counterpart and more reactive. It forms mononuclear and polynuclear oxides and hydroxides (Smith et al., 1995). Low

In this experiment redox-based titrimetric analysis was used to determine the amount of ascorbic acid (Vitamin C) contained in a serving of lemonade. This was done to confirm the 100 percent recommended daily allowance claimed on the package for a serving of Country Time Lemonade. The titration method used was adding a thyodene indicator to the analyte (lemonade solution) there is a visible colour change when the endpoint of the reaction between the titrant (KIO3) and the analyte occurs. The following
