hydrogen chloride has properties: Hydrogen chloride has one molecule of hydrogen and one molecule of chlorine: Hydrogen chloride has a very powerful smell. It is in the form of a gas but only when it is at room temperature which is approximately 25 Celsius and when the pressure is high. The solubility of hydrogen chloride is very high this means that it can dissolve in water quickly because it dissolves many times in its own solution (the gas form of hydrogen chloride). It is very soluble because the smaller the chain of the molecules are then the energy required in small quantities however if the chain is long then it will need more energy so that means that the longer chain will have a slow reaction and the longer the chain the chances…

There will be three exams (On Sept 24, Oct 25, and Dec 3) and a comprehensive final. Each exam will count for 20% and the comprehensive final will count for 30% of the total grade for the class. If the final grade is higher than the lowest exam grade, that exam grade will be dropped and the final will count for 50% of the total grade. There will also be problem sets on blackboard that will count for 10% of your total grade. You may collaborate on these problem sets. All material on an exam will be covered at least one week before the exam. The minimum score for each letter grade (out of 100) is: A 90, A- 87, B+ 84, B 80, B- 77, C+ 74, C 70, C- 67, D 64.…
The use of fluoride in America is an example of the FDA abusing the public’s trust, all for the sake of profit. Fluoride is a natural occurring mineral in the environment. Fluoride levels in water vary around the world, depending on the type of rock and sediment in a region. The higher the fluoride content in water, the greater the likelihood of cancer, malformed babies, mental retardation, bone disease, and severe dental problems (Richards 133). There are certain guidelines set by the FDA that are supposed to protect the public from ingesting too much fluoride. They have set the safe upper limit for drinking water at four milligrams per liter of…

Failure to drink fluorinated water and use a fluoride toothpaste will result in increased tooth decay. Talk to your dentist about receiving a prescription, extra strength fluoride toothpaste.…
From 1985 to 1997, school districts decreased the amount of milk they bought by nearly thirty percent and increased purchases of soda by one-thousand and one-hundred percent. (Roberts) About fifty-six to eighty-five percent of school age children consume at least one soft drink daily. (Roberts) Children these days are not getting enough calcium, mainly because of the large consumption of soft drinks. Instead of grabbing a glass of milk, most kids, teens and adults would rather drink soda. The effects of the preservatives and artificial sweeteners can break down the enamel on your teeth, making them prone to rotting. The reason that most people who drink to much soda have or are more prone to rotting teeth, cavities, etc., is because sugary drinks coat you teeth, gums and tongue for hours after you drink them, and most people don’t rinse or brush their teeth right after drinking soda. (Anne) When tooth decay starts to reach the nerve, the root, and the area at the base of the tooth, the tooth may die and, if let untreated, an abscess can develop. (Term Life Insurance) Drinking soda through a straw can help prevent corroding your teeth because the beverage goes straight into the back of your throat. (Anne) Soda has a pH of 2.5 to 3.0, or around…
They compare adding fluoride to water and adding iodine to salt, saying that even though it is toxic in large amounts, it is essential and therefore beneficial. There are several things wrong with this claim, the first being that if one tried to consume enough salt to get iodine poisoning, he would first poison himself with an extreme excess of salt. Another issue is that iodine is an essential nutrient, and iodine deficiency can cause severe brain damage, but fluoride is not an essential nutrient, and it is entirely possible to have healthy teeth without ever touching…

Caries prevention is extremely important for not only kids, but adults as well. There are different ways that people can do this, but one of the easier methods is by using fluoride. Fluoride is commonly known for preventing dental caries and also helping with strengthening bone. There has always been a controversy that fluoride is extremely bad for the body and that it should not be allowed to be in public water. Besides water, fluoride is also found in food and beverages, known as a form of systemic fluoride that many people also believe is problematic. Toothpastes and mouth rinses account for two of the three primary fluoride caries prevention methods as well as water. What many people may not know or understand is that fluoride is actually…
