Theobromine 3,7-dimethylpurine-2,6-dione, more commonly known as theobromine is an alkaloid. Theobromine gets its name from Theobroma which is comprised of two Greek words, theo (god) and broma (food). It is composed of carbon, oxygen, nitrogen and hydrogen atoms, the molecular formula being C7H8N4O2. All these atoms together produce a molecular weight of 180.167g/mol. Theobromine has a hexagonal part and a pentagonal part connected by two carbons with a double bond between them. The interior angles for the hexagonal portion are all 120. There are two ketones on the second and sixth atom’s, both are carbons because they are carbonyl groups. They both form 120 angles with their respective carbons. Also on the hexagonal part is a hydrogen attached to a nitrogen bonded at an angle of 107 up (not on the same plane) because of the lone pair of electrons. Both the hexagonal and pentagonal part have a methylpurine group on atoms 3 and 7 which are both nitrogen causing them to have a bond angle of 107 up (not on the same plane) because of the lone pair of electrons. These two groups have a tetrahedral shape making all the angle around the carbon to be …show more content…
The interior angles of the pentagonal portion of theobromine are 108 except for the nitrogen, with a signal bond to a carbon and a double bond to another carbon, which has an angle of 104.5 because it is
In March of 1768, in present-day Ohio, Tecumseh was born. Tecumseh's name means "Panther in the sky." Tecumseh was the fifth born in his family. His mom, Methotaske, was a Creek, and his dad, Puckeshinewa, was a Shawnee. He excelled at the game's Indian boys played. He also organized other boys to go on hunts. When Tecumseh was younger he admired and looked up to the warriors, like his older brother. He also tried to be like the warriors. Later in his life, Tecumseh became a powerful chief to the Native American Tribe, the Shawnee's. He did not want the Americans to take the Native American's land. He accomplished many things in his life.
Holmium is a chemical element and is the sixty seventh element on the periodic table. It is located in Period six and it is a member of the lanthanide group. It was discovered in 1879 by a Swedish chemist named Per Theodor Cleve. Like Carl Gustaf Monsander who discovered the elements lanthanum, erbium and terbium Theodor also used similar strategy's to find contaminants in the oxides of uncommon earth elements. He first looked at the oxide of erbium and was able to split it into two types of materials one being brown and the other green. This in turn caused Theodor to find the oxide of holmium (it was the brown material which is known as holmia) and this was how the element holmium was discovered.
“I am Sick - discontented - and out of humour. Poor food - hard lodging - Cold Weather - fatigue - Nasty Cloaths - nasty Cookery - Vomit half my time - smoak’d out of my senses - the Devil’s in’t - I can’t Endure it - Why are we sent here to starve and Freeze…” Valley Forge, the hell of the American Revolution. The American Revolution was a war between what is now known as the United States, and Great Britain, in which the United States were fighting for their freedom. The reason for British inclusion was that they needed the colonies (the United States) for resources and for taxes. Three years into the American Revolution and it’s Winter, 1777. General Washington needed somewhere secure to relocate his army for the Winter. Enter Valley Forge, a military camp in Pennsylvania. If I had a choice of either staying in Valley Forge for the Winter or returning home, I would not have stayed in Valley Forge for the following reasons; sickness and death were rife, the living conditions were horrendous, and the continental army was running out of supplies.

Tyler Joseph is most known for being the co-founder and frontman of the American band Twenty One Pilots (usually stylized as twenty | one | pilots or twenty øne piløts). He was born in Columbus, Ohio, on December 1st, 1988. He was born to Chris and Kelly Joseph, the first of four children. He has two brothers, Zack and Jay, and a sister, Madison. He and his siblings were homeschooled for most of elementary school and middle school, before later attending a private Christian high school. Throughout his homeschooling and years in high school, basketball was always a big part of his life. His father was a school principal, and his mother a math teacher, and both coached basketball. After practicing for years at home, he went on to play point guard for Worthington Christian School's boy's basketball team.
There are seven cubic forms or isometric forms. In these forms the three crystallographic axes are also the four fold rotation. In this system there are also four a...
The IR spectrum that was obtained of the white crystals showed several functional groups present in the molecule. The spectrum shows weak sharp peak at 2865 to 2964 cm-1, which is often associated with C-H, sp3 hybridised, stretching in the molecule, peaks in this region often represent a methyl group or CH2 groups. There are also peaks at 1369 cm-1, which is associated with CH3 stretching. There is also C=O stretching at 1767 cm-1, which is a strong peak due to the large dipole created via the large difference in electronegativity of the carbon and the oxygen atom. An anhydride C-O resonates between 1000 and 1300 cm-1 it is a at least two bands. The peak is present in the 13C NMR at 1269 and 1299 cm-1 it is of medium intensity.
The isomerization procedure was done in order to create dimethyl fumarate from dimethyl maleate. Dimethyl maleate and dimethyl fumarate are cis and trans isomers, respectively. This procedure was done via a free radical mechanism using bromine. The analysis of carvones reaction was done in order to identify the smell and optical rotation of the carvone samples that were provided. The odor was determined by smelling the compound and the optical rotation was determined using a polarimeter.
Serephena is the goddess of sickness. She grew up as an awkward child. She was always being made fun of because she would always sneeze. Her parents didn’t know why she sneezed all of the time, so they shunned her because they thought she wasn’t normal. One day, Serpehena was playing with her friend Eretria. They were playing on the playground at school. Serephena sneezed on her, and then Eretria started sneezing too. Eretria freaked out, and told everyone in the school. After that, people made fun of Serephena for the rest of her school years. When Serephena was a teenager, no one would date her because they thought she was weird and abnormal.
In one molecule of Cocamidopropyl Betaine there can be found “both anionic and cationic structures” ( heraproject.com, 2005, p.5). At a low pH, the cation has the greater effect. It has a very high boiling point, 760 degrees Celsius. It has five H bond acceptors, two donors, and 16 freely rotating bonds. This bond ratio is responsible for the high boiling point. As displayed by the name, Cocamidopropyl Betaine is a betaine. All betaines contain a four bonded Nitrogen atom. They always have two functional groups with opposite electrical charges. Because of this characteristic Betaines are often regarded as inner salts. Ot...
According to the Online Entomology Dictionary, the word Bless is derived from the “Old English bletsian, bledsian, Northumbrian bloedsian "to consecrate, make holy, give thanks," from Proto-Germanic *blodison "hallow with blood, mark with blood," from *blotham "blood"…. Originally a blood sprinkling on pagan altars.” The word Blessed is noted to have come into common use in the 12th century, meaning to be “supremely happy” or “consecrated”. Used interchangeably with the word blest, blessed is used in describing something that is holy, revered, or worthy of worship.
As someone that has been called from darkness into the Kingdom of light, proclaiming the good news to the entire world is not only a matter of necessity but it is also compulsory, and it requires our immediate action. {1 Peter, 2:-9}
Francesco Petrarch, otherwise known as the “father of humanism,” played a vital role in igniting the Renaissance Period (Whitfield). His works and ideas influenced many other poets and writers after his death. Petrarch was known for his deep and symbolic works that are still read and analyzed today. Petrarch’s father’s death began his full onset of studying and writing literature (Whitefield). Francesco Petrarch focused on studying classics, and he was the epitome of what a Renaissance Period writer should be; through his famous Petrarchan Sonnet, he was better able to bring out important themes and stylistic devices that highlighted his love for Laura and how death interfered with his ability to love her .
In 2008, a group of university and college presidents expressed their displeasure with the minimum legal age of 21 years old by signing the Amethyst Initiative. Led by John McCardell, The amethyst initiative is a group of one hundred and thirty six college presidents who show support for lowering the legal drinking age from 21 to 18. The name “Amethyst” reflects on the purple gemstone which was sought to ward off drunkenness if used in drinking vessels and/or jewelry. Though the Initiative sees good in lowering the requirement, they want to perform an informed and dispassionate debate rather take action for change in legal matters. The college presidents do not encourage teenagers to be allowed to drink to their heart's content, but rather to allow the young adult one more responsibility.
These tetrahedrons together form a 3-dimensional network of six-membered carbon rings (similar to cyclohexane), in the chair conformation, allowing for zero bond angle strain.
The Amethyst is my absolute favorite stone and always has been. Ever since I was young, I have been drawn to it. As purple is my favorite color and I just can’t seem to stay away from it, I love the vibrancy the color of the Amethyst gives off. It seems to me like a source of solace, and when I have one close in a time of need, it gives me the feeling of being wrapped in a comforting blanket. As it feels this way, I am sometimes tempted to put it against my face, as you would a childhood stuffed animal or blanket. For some reason, Amethyst continuously sparks a fire of admiration in me and this is why I have chosen to do my research paper on the matter.
