sections also can be used when discussing certain planes that are formed when they are intersected with a right circular cone. The planes, or lines as we know them, consist of the circle, the ellipse, the parabola, and the hyperbola. (West, 112) There are different ways to derive each separate curve, and many uses for them to be applied to as well. All of which are an important aspect to conic sections. The cone is a shape that is formed when you have a straight line and a circle, and the straight

which is [He]2s^22p^3, as well as its density which numbers 1035 K. Nitrous oxide, symbolized by N2O is one of the compounds formed by Nitrogen. This compound was discovered in 1776 by Joseph Priestley. This compound is actually a very easy compound to make. It can be made right at your own home. It involves heating ammonium nitrate to a temperature between 170 degrees Celsius and 240 degrees Celsius in which it breaks down into nitrous oxide and water vapor. The formula is noted as “NH4NO3(s)-2H2O(g)+N2O(g)”
molecules can move freely and bump into each other, and in plasma the molecules have completely broken apart. These molecules are too small to see and are different for every object. So what do particles have to do with vinegar and baking soda reacting? Well acids and bases are made of elements. These elements are made of atoms which are made of molecules. So when you get down to it, the reaction between acids and bases all depend on the particles of the object. When you mix baking soda and vinegar you
feeding a child. Breastfeeding is an issue of gender because when a woman is seen breastfeeding, in public or not, she is usually shamed and accused of indecent exposure. This is because our society has been shaped to see breast only as sexual objects as well as an insufficient amount of educating on breastfeeding being done. We could start to put an end to this issue by becoming informed on the importance of breastfeeding and realizing that the purpose of breast is to provide nutrients to babies. In the
The purpose of this lab is to determine the empirical formula of copper oxide (CuxOy) through a single-displacement reaction that extracts the copper (Cu) from the original compound. In order to do this, hydrochloric acid (HCl) was mixed in with solid CuxOy; the mixture was stirred until the CuxOy was totally dissolved in the solvent. Zinc (Zn) was then added to the solution as a way to enact a single displacement reaction in which Cu begin to form on the Zn; the Cu gets knocked off the Zn through
some of the most useful and common compounds. The most familiar one is sodium chloride, which chemical formula is NaCl. Sodium chloride has a molar mass of 58.44 g/mol, a melting point of 1,474̊ F, and a boiling point of 2,575̊ F. Sodium chloride is created when a sodium atom gives one of its electron to a chlorine atom, thus creating a sodium cation and a chlorine anion. Another compound formed with sodium is sodium bicarbonate, or NaHCO3. Which has a molar mass of 58.44 g/mol, a melting point of
There’s a handful of the different types of chemical reactions to become familiar with. Not only does a chemical reaction have the physical signs of a change, but the formula of the reaction can change as well. Bimolecular reactions are when two molecules come together and react with each other. This is called Chemical Synthesis. This formula can go from A+BAB. Chemical reactions are everywhere, from frying an egg, to making a liter of Pepsi, there is much more that goes on within the process rather than
acid. Among the most important aldohexoses are glucose, mannose, and galactose; fructose is a ketohexose. Several derivatives of monosaccharides are important. Ascorbic acid (vitamin C) is derived from glucose. Important sugar alcohols (alditols), formed by the reduction of (i.e., addition of hydrogen to) a monosaccharide, include sorbitol (glucitol) from glucose and mannitol from mannose; both are used as sweetening agents. Glycosides derived from monosaccharides are widespread in nature, especially
Finding the Empirical Formula for Magnesium Oxide The Results In order to work out the ratio for magnesium and oxygen, I will have to calculate the amount of magnesium and oxygen used. [IMAGE] From these results, and knowing that the Ar for Magnesium is 24, and the Ar for Oxygen is 16, I can find the number of moles for Magnesium and Oxygen. Investigation 1: Magnesium = 36.08 - 36.04 = 0.04g Oxygen = 36.11 - 36.08 = 0.03g Magnesium Ar = 24 Oxygen Ar = 16 --------------------------------
and mean ratio. Whit this formula the Greeks answered to the question: how can we divide a line in two sections to have the most appeal balance? The Greeks claimed that the most visually pleasing division has the property that the ratio of the length of the entire line segment to the length of the long piece, and they expressed with this formula: L/1=L+1/L. It seems kind of confusing, but with practice it will be easier to appreciate it on art expressions. This formula helped to find what we know
put letters into a formula. This is how it would look: (P+10)(P+1)- P (P+11) = 10 When we multiply out this formula it looks like this: P²+11P+10 -P² - 11P = 10 As it shows the result is 10 once again P²+11P+10 -P² - 11P = 10 Testing the Formula Now we can put the formula to the test by using it with numbers: (23x32)- (22x33) =10 [IMAGE][IMAGE] = As we can see the formula has proven to work well and the result is once again 10 as the formula suggests. Now that
spectroscopy, and the index of hydrogen deficiency (IHD) to identify the structures of two unknown compounds. To ensure the successful identification of the unknowns, the molecular formula for each compound was found first. What the molecular formula does is that it allows chemists to identify elements present in a compound as well as the quantity of each element. The issue with this is that there are various compounds that share the same molecular compound yet are different in reactivity and connectivity

Organic compounds have many useful real world applications and are important
hydration is heated out of the hydrate when the temperature reaches above 100℃, since the hydrate bonds are weaker than the ionic bonds that are formed between the salt ions. The water is driven off, leaving the anhydrous salt behind. BaCl2●2H2O (s) + heat → BaCl2(s) + 2H2O (g) Is an example of this as the BaCl2●2H2O is the hydrate,
The Fibonacci Sequence Though the name sounds intimidating, the Fibonacci sequence is just a series of numbers obtained by adding the previous two entries together to get the new entry. The sequence, though usually only found within mathematical problems, can be applied in various ways, and is found in nature. It is related to several mathematical concepts, like the golden ratio and Pascal’s Triangle. It is involved in almost every aspect of life, including education, natural events, and even
