Lead exposure takes place as soon as lead dust or fumes are breathe in, or once lead is ingested. Lead entering the respiratory and digestive systems is released to the blood and dispersed throughout the body. Additionally, more than 90% of the entire body encumbrance of lead is accumulated in the bones, where it is stored. Lead in bones may be released into the blood, re-exposing organ systems long after the original exposure. The toxic nature of lead is well documented. Lead affects all organs

Copper Transformations Prelab Questions Three metals ions are Magnesium, Iron, and Nickel. Iron is used in the sea with iron rich minerals, for substances. Iron was also used in the formation of earth. Magnesium is used in cells of every organism. It helps balance out the functions within the cells. Nickel is used for light absorption in natural environments. Nickel is also used in rings for a cheap substance rather than silver or gold. The material needed for this experiment include a 100mL

magnesium. The solutions are copper nitrate, silver nitrate, zinc nitrate, and magnesium nitrate. If the element is in the alkali earth metals such magnesium than it should be more reactive with the solutions than most groups and the metals in the transition metals should have some reaction to some solutions. Alkali earth metals are pretty reactive while transition metals are less reactive. Analysis:

AIM Design an experiment to study a thermodynamic property of a chemical substance, a chemical reaction, a physical change or chemical phenomenon. BACKGROUND INFORMATION Standard enthalpy change of solution, ∆Hsolnø, is the enthalpy change when one mole of a substance dissolves in water to form a solution of infinite dilution under standard conditions.1 The standard enthalpy change can either be exothermic or endothermic. An exothermic reaction is a reaction where energy is released as a form of

Heavy metal – a Dutch oven materials review A typical Dutch oven is made of cast iron and comes with a lid. You can wear and tear them because they have a reputation for being durable and reliable. Dutch ovens made of cast iron were used for centuries, but recently there has been a development in technology which resulted in Dutch ovens made of various materials: aluminum, glass, porcelain, steel, you name it. In this review we will give you a rough sketch of what to expect from each material. Various

Titanium Dioxide (TiO2) is known as the ultimate white pigment because of its high refractive index and also its brightness. This dust is naturally occurring from the oxides of titanium. This compound has many application uses. These include Paint manufacturing, food coloring, sunscreen products and the Pharmaceutical industry to name a few. According to the IARC (International Agency for Research on Cancer), it is classified as a Group 2B Carcinogen, basically it states that it is potentially cancerous

In the equation, Al metal was oxidized to aluminum with an oxidation number of +3 and the hydrogen in KOH or in water was reduced from an oxidation number of +1 to zero in hydrogen gas. Reaction #2 was an acid-base reaction. The H^+ ions from the sulfuric acid neutralized the

The chemical elements are divided into two broad groups, the metals and the non-metals. In this experiment, you will examine some members of the metal group and identify similarities and differences in their physical and chemical properties. Metals are the elements that are found in the left of the periodic table with high electrical and thermal conductivity. Metals lose electrons to create positive ion charges. Metals have a unique shine, are prone to forming, have a high tendency to form cations

4.1.1. Definition Asbestos is a naturally occurring minerals that are resistant to heat and corrosion. Asbestos has been used in products, such as insulation for pipes, floor tiles, building materials, and in vehicle brakes and clutches. 4.1.2. Physical and Chemical Characteristics There are six types of asbestos minerals, according to the Environmental Protection Agency (EPA): chrysotile, amosite, crocidolite, tremolite, anthophyllite and actinolite. Asbestos is inert, insoluble in water and

Plato’s Protagoras is a dialogue of much debate that allows for the readers to look further and to bring into question the argument on virtue for themselves. It is not something to be taken whole-heartedly since Plato is throwing different theories about virtue around in this dialogue. Socrates, one of the main characters was always fixated on virtue, especially the concept of defining and teaching virtue, and whether or not it can actually be taught. However, one must keep in mind that Socrates

Calcium chloride is commonly used as the main ingredient in road dust control products because it has the ability to hold on to moisture for a longer period of time. Therefore, this keeps the dust from becoming airborne. Since the dust remains settled on the ground this creates a smooth surface that is easy to drive on. One of the reasons why calcium chloride is so effective is due to how it is handled prior to use. If the chemical substance is stored incorrectly this can ruin your roads and create

Referencing our data, it can be determined that out of the three metals, Pb, Cu and Zn, it is shown that Lead (Pb) is more active than Copper (Cu) due to single-replacement reaction that took place. Lead had replaced Copper in the solution. Zinc (Zn), however, had replaced Lead thus leaving Copper to be the least active leaving Zinc to be the most active out of the three. In order of activity from least active, to most active, the metals would be lined up as following: Ag, Cu, Pb, Zn, Mg. From this

Rhenium is element 75 on the periodic table as a metal. It is located under manganese, but it was not always there. Rhenium was discovered by Walter Noddack, Ida Tacke and Otto Berg in 1925. Rhenium is one of the rarest metals on earth with the melting point of 3185-degrees Celsius, 5,765 degrees Fahrenheit. The only element with a higher melting point is Tungsten. Rhenium can

Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called

The element cesium is an element like no other. It has many characteristics that separate it from many of the other elements that most people know. Cesium also has important uses for our society and we can benefit from it a lot. Cesiums story starts way back in 1860 Heidelberg Germany, with two German chemists by the names of Robert Bunsun and Gustav Robert Kirchoff. A year before they discovered the element cesium, they developed a spectroscope. This tool allowed them to see the atomic spectra

In performing these sets of experiments, in which we would drop a water/water solution onto the surface of a penny, we were trying to test and experiment the bonding qualities of water when made into a solution compared to when the water is pure. When we dropped pure tap water on to a penny, the water, instead of flowing and spreading out, stayed together in a single drop on the penny. We wanted to see how different substances affected this phenomenon. When we formulated our guiding question we

Blood Diamonds Diamonds are carbon products that are used for two main purposes. They are an ornamental jewel which is globally accepted as a precious stone, used as gifts or as a symbol of love. Industrial jewels are used in industries to make drills and other industrial equipment. Diamonds are also used as investments where, stockbrokers would substitute their money for the diamond with the idea that the prices of diamonds do not fall (Documentary Tube, 2015). Blood diamonds refer to diamonds

Many ores contain valuable metals that can be extracted and used for construction, infrastructure, and more. Extraction is a technique that allows large pieces of ore to be broken down into pieces small enough for the valuable metal to be removed. Metal extraction is extremely important technique because the metals inside ores have special properties such as strength, durability, malleability, and ductility. 1 Iron, copper, aluminum are a few examples of widely used metals that are commonly extracted

Project 1: Calorimetry CHM2046L-029 24920 Introduction Background Calorimetry is a method of measuring the enthalpy (heat energy gained or released) of various state changes, such as chemical reactions. Calorimetry can also be used in a number of other ways, however, including in microbiology (where the presence of various microorganisms can be determined as their multiplication increases thermal power) and in environmental science (where a calorimeter can be used to determine insect
