Calamine Investigation Introduction. Calamine is a mineral containing Zinc Carbonate (Zn CO ). On heating it decomposes as follows: ZnCO -------ZnO+ CO (C= 12, O= 16, Zn= 65) The equation allows you to calculate a theoretical conversion of calamine into zinc oxide. In the chemical industry they need to be able to calculate % yields in order to make sure that their processes are economical. Aim. I am going to compare the results from the experiment with the theoretical
Obtaining Zinc Oxide from Calamine Introduction Calamine is a mineral containing zinc carbonate (ZnCO₃) On heating it decomposes as: [IMAGE]ZnCO₃ ZnO + CO₂ (C = 12, 0 = 16, Zn = 65) This equation allows you to calculate a theoretical conversion of calamine into zinc oxide. As when using the theoretical conversion; [IMAGE]ZnCO₃ ZnO + CO₂ [IMAGE]65+12+48 65+16 + 12+32 [IMAGE]125 81 + 44 This means that one mole of calamine weighs 125g and when heated it produces
little use of it (Mathewson 1). The unassuming bluish-gray mineral was given a warmer welcome by the Romans, who were already using it to make brass by “about the time of Augustus, 20BC to 14AD”; the Romans used, not purified zinc, but the mineral calamine (“zincky wall accretions” from caves) and fused them in a crucible with bits of copper to make their brass (Mathewson 1). Around the world, zinc was being exploited by the Chinese civilization as well, although documentation of Asian use of zinc
Skin discoloration of the lower legs, ankles and feet may appear if there is increased pressure in the leg veins. The pressure may be the result of venous stasis. This is a condition in which there is poor blood flow from the legs back to the heart. It usually occurs when varicose veins have formed and the blood starts to pool in the veins and becomes stagnant. As it accumulates, small and medium sized veins may spring a tiny leak and some blood passes into the tissue. Once in the tissue, the blood
Zinc, the thirtieth element on the periodic table, has many uses in our modern lives. It’s uses vary from directly making many consumer goods to making alloys used in the development of other everyday products. And it’s uses do not stop at the industrial. Zinc is also important for natural growth and healing in plants and animals, including humans. In all, zinc is a very important element for our lives, both in our natural and commercial well-being. As for it’s history, the usage of zinc dates back
Varicella or more commonly known as chickenpox is a vaccinatable disease. In the United States it has been vaccinatable since 1995. (Marin, 2011, para 1) Chickenpox usually affects children and teenagers, but any age can acquire the virus. Typically people will experience a fever and itchy rash that eventually fills with fluid and turns into a blister. (Center for Disease Control and Prevention, 2016) Chickenpox can be very uncomfortable for the person who has been infected and can lead to scarring
filled blisters and eventually into scabs. Fever, tiredness, loss of appetite, and a headache can also be present. The symptoms can last 5 to 10 days. Nursing interventions is to educate parents on the importance of immunizations and to provide calamine lotion to the infected patient to help relieve itching. http://www.cdc.gov/chickenpox/about/prevention-treatment.html Candidias is a fungal infection caused by yeast belonging to the Candida genus. Candida morally lives on skin without causing
The Varicella-Zoster virus, is also referred to most commonly as Chickenpox, it’s a very contagious disease. (NCIRD, 2016). “Its genus is the Varicellovirus, and its species is the human Herpes virus.” (NCIRD, 2016, paragraph 1). A sign of this disease is a rash, which will cause discomfort and be very itchy. The rash will fill with fluid and turn into blisters, eventually progressing to scabs. The rash appears on the face, back, and chest, then spreads to the rest of the body. (Anonymous, 2016)
CAFFEINE ALLERGY HOME REMEDY Caffeine allergy is a reaction in the body’s immune system due to consumption of caffeine or any caffeine products. It is available in drinking tea, soft drink, coffee, chocolates. It is also available in drugs to treat headaches, cold pills and pain relief. It is found that the consumption of caffeine among the adult US population is 80% in the form of food or other medication. A common term is used for the allergic reaction to caffeine and is known as anaphylaxis
Chickenpox, Adult Chickenpox is an infection caused by the varicella-zoster virus. The infection causes an itchy rash that turns into blisters, which eventually scab over. This virus spreads easily from person to person (contagious). It is contagious starting 1–2 days before the rash appears. It remains contagious until the blisters become crusted. Chickenpox can be very serious for adults. Complications of chickenpox include: • Pneumonia. • Skin infection. • Brain infection (encephalitis)
Tomato allergy is a food allergy which is not common. However it becomes a real big problem to people who are allergic to tomatoes. The allergic reaction seems to be because of the skin, seeds and juice. This allergy falls in Type 1 Allergy also called contact allergy. The oral allergy to tomatoes can be also due to the cross-reactivity to grass pollens and Ryegrass. Since tomatoes and potatoes are close related plants, therefore there is a slight chance of being allergic to potatoes also. Ingesting
Chicken pox, also known as varicella, is a contagious viral disease. Varicella was first recorded more than 400 years ago. It is caused by the varicella-zoster virus, or VZV. VZV is a type of herpes virus. The varicella-zoster virus can cause two diseases. It can result in chickenpox or shingles. Chickenpox is typically mild, but can sometimes cause serious complications. chickenpox can be serious. A vaccine was developed for VZV in 1944, but before then it was a common adolescent disease. For children
Vaccines are a big part of the modern world. They help our immune system in the same way someone runs a training course; preparing for something they may encounter in the future. Vaccines have many benefits that can help in the long run, that is why I stand in firm affirmation that vaccines should be required for children. To clarify, a vaccine provides active acquired immunity to certain viruses and diseases; a vaccine is biologically prepared. I offer the following contentions in affirmation
Many people can remember a time when they were a little kid and tiny little red bumps began to form on different locations of their skin. The small bumps began to spread and began to itch. Remembering the pink color of the calamine lotion that was used to soothe the itching sensation, realizing that these bumps were chicken pox. It is common knowledge that once a person contracts chicken pox and the outbreak clears up, the person will not get an outbreak again. Yet there are unknown complications
Varicella zoster virus Varcella zoster virus is commonly known as chicken pox and shingles. It 's part of the DNA virus family also called Herpesviridae. The Herpesviridae family consists of eight different species that is identified to infect humans. The first two Herpesviridae species: HHV-1 and HHV-2 caused herpes labialis and genital herpes. Varicella zoster species is HHV-3 virus that is a recurrent virus, similar to other herpes viruses. Varcella zoster virus has the ability to persist
First Aid and CPR In the medical field we have a variety of procedures that can be performed to help people and patients feel better or how to save a life. Some of the procedures that are performed can be done by professionally trained personnel, or by anyone. Two very important medical procedures that are very common are First Aid and Cardiopulmonary Resuscitation (CPR). Both First Aid and CPR are used on a daily basis and are used worldwide, even if used in a slightly different manner the basic
which makes the vaccine unnecessary. The main vaccines that we hear about are chicken pox, measles, and rubella. All of these diseases are normally harmless, chicken pox usually consists of a rash with blisters and can almost always be treated with calamine lotion, acetaminophen, and a cool compress. The measles is usually a rash with a fever and a runny nose. This can be treated with rest and fluids. Rubella is usually a virus with a rash and fever that can be treated with
Second largest country in Africa, tenth largest country in the world, diverse culture extending from the Mediterranean coast to the dunes of the Sahara Desert...Algeria. Even with its massive size the current status of Algeria’s economy is quivering in the lofty winds of the Tell Atlas Mountains. The economy tends to remain dominated by the state, which is accordingly a legacy of the country’s socialist post-independence development model. Hydrocarbons are the backbone for Algeria, accounting for
Chickenpox is a highly contagious disease that is caused by a herpesvirus called varicella-zoster virus (7). Chickenpox is one of the most easily transmitted of contagious diseases (5). Ninety to ninety-five percent of the people exposed to the virus will develop it within twenty-one days (5). The term chickenpox came from chickpea, which is a member of the bean family and resembles the look of the swollen pox, or from the Old English gican, meaning “to itch” (7). Before chickenpox was classified
Have you ever had or witnessed someone with Eczema? Well it is not fun having or experiencing this skin disease. Eczema is a chronic skin disorder that cannot be cured and causes the skin to become itchy, red, and dry, but it can be treated by dieting, home remedies, medications, and therapies. People coping with this disease try many forms of these treatments and even try to come up with some of their own treatments. Dealing with eczema can be a lifelong process for people who have it.
