Zinc Chloride Is Surrounding Us

Why i chose zinc is because it seemed interesting to me in the things it was used for.

Zinc, a common mineral located on the periodic table, plays a significant role in how our bodies function. Found in different foods like meats, nuts, dairy products and certain vegetables; Zinc is an essential nutrient that the body needs on a regular basis. The RDA (Recommended Daily Allowance) of Zinc for adult males is 11mg per day and 8mg per day for females. A daily intake of zinc is recommended because the body does not have a specific way to store it. Besides not having a way to store Zinc, it can be found in the majority of all tissues in the body. Zinc functions as a cofactor to more than 300 different enzymes specifically regarding the human metabolism and its functions. Some of the specific functions that zinc is apart of in the

Zinc, number 30 on the periodic table and a bluish-white metallic element, exists naturally in air, water and soil. It is present everywhere in the environment. All life on earth has evolved in the presence of zinc. Natural processes such as erosion, forest fires, aerosol formation above the seas and volcanic eruptions continuously transport Zinc. Zinc melts at about 420° C and boils at about 907° C. Zinc is efficient for plants. Zinc-deficient soils present in many parts of the world are a cause of low crop yields. Not only does it help plants but also the human body. It is responsible for the proper functioning of more than 300 enzymes in the human body, and is vital for the immune system. It will also fight against cold

When all quantitative data has been collected and recorded, use the equation below to calculate the average electrical potential difference, or Average E_Cell of each variation of Copper Chloride.

Zinc chloride is an ionic compound. An ionic compound is made up of two elements, a metal and non-metal. They also consist of positive and negative ions. When an ionic compound is formed the ions bond to make a zero charge. The second element (the non-metal) is named by adding –ide to the end of it, providing it is a monatomic ion. The mixture of zinc chloride contains a metal (zinc) and a non-metal (chloride). Zinc has a charge of +2 and Chlorine has a charge of -1, so it consists of a positive and negative ion. Thus when zinc and chlorine combine, it actually takes 2 chlorine ions to bond with 1 zinc ion. This would give the formula a zero charge, and also make it an ionic compound. Finally, the name of the non-metal ion is chlorine, in this experiment it becomes chloride, adding –ide to the end also is proof it is an ionic compound since this is a bond between a metal and non-metal, and since there is no prefix in the name.

Toxicology-Toxic - may be fatal if swallowed or inhaled. Corrosive, causes burns. Harmful by inhalation and through skin absorption.

Seeing as though you I don’t know think that you know much about zinc I’ll tell you about it. Zinc is considered an ore, as an ore is a naturally occurring material that contains a high enough concentration of metal in it to make it worth extracting the metal from it.

Zinc is a nutrient that people need to stay healthy. Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses.

Zinc is an essential mineral, it is either added or naturally present in foods. You can find since added in many cold lozenges and a few over the counter cold remedies. There are numerous aspects of cellular activity that zinc is apart of. A few examples would be protein synthesis, wound healing, DNA synthesis, and cell division. While Zinc can also support a normal growth and development for women during pregnancy, as well as a child and adolescence. A daily intake of zinc is needed in order to maintain since the body has no specialized zinc storage system. To determine the proper intake recommendations of Zinc, using the Dietary Reference Intakes can help determine the right amount.

The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures.

Based solely upon heat transfer properties the 3 materials that were considered were copper, aluminium and zinc alloys. Zinc was immediately discounted due to how easily it undergoes corrosion, which could potentially lead to leaks and system failures. While both metals are quite similar in terms of thermal conductivity, copper is priced at $3.14 AUD per kg while aluminium is priced at $0.94 AUD per kg (Appendix A). However, due to the flimsy nature of aluminium, it is extremely difficult to design a system utilizing aluminium coils to last. It should also be noted that there is a precedence where aluminium coils were used for a time but were extremely difficult to repair and maintain as well as the need for a bulkier housing unit for the system

Zoé Zincum was with her friends from college on spring break in Peru. She was in a spelunking accident. Her and all four of her other friends fell into a pool of mysterious liquids containing various metals and they didn’t know. There was Iron, Cobalt, Copper, Nickel and Zinc. Zoé acquired all of the powers of Zinc. Her friends acquired all the other metals powers. On their way home Zoé’s plane flew into a harmful part if the atmosphere and she got very scared because it started to get hot and they were burning alive. Zoé started protecting the whole plane soon. Once she realized she had these amazing powers, she started healing everyone who got hurt and then she used her amazing vision to see through the clouds. There was a perfect spot to get close enough that they could jump. Everyone jumped and held onto her hair so that she could dig her nails into the mountain to slow the down. Zoé helped all of these people get home safe.

4. Acetic acid was used in the synthesis of zinc iodide because an addition of a weak acid prevents the formation of Zn(OH)2 that occurs when zinc and iodine react with deionized water. The formation of the precipitate inhibits the production of the product ZnI2 and may make it seem as if the basic law of conservation of mass was not obeyed. Since acetic acid and water are both volatile, they can both be easily removed from the solution by heating which would possibly leave behind more ZnI2 . When the acid is not added, it is interesting to observe the Zn(OH)2 precipitate that is formed.

For external use only, if bag busts dispose of it immediately. Prolonged skin exposure to the chemicals can cause dry and red skin. If the chemicals do get onto skin wash the area with soap and water, then contact a physician. Do not inhale the chemicals, calcium chloride can create lesions in the mucous membranes that line the nose, throat, and lungs if inhaled regularly. If you begin coughing or have a sore throat, the IPCS recommends moving into a well-ventilated area and resting until your symptoms subside. If symptoms persist, see your doctor.

In this experiment, there are no significant ethical considerations as we had not used any living organisms. There were no extreme safety concerns, however there are still precautions that needed to be taken. Cobalt chloride is very toxic and is irritating to the skin so when handling the cobalt chloride solution, wear lab coats and safety goggles and have all hair tied up. Handle the solution with care to try and prevent the solution from coming into contact with skin. If it does spill onto skin, wash it off with water and soap. Do not touch your eyes when handling this substance to prevent it from entering your eyes.
