games are more exciting and ultimately more people are in the stands. Mark McGwire confessed using human-growth hormones to recover from injuries (CBSnews). Steroids were also used to prolong major league careers and extend players prime. In Barry Bonds’ case, his home-runs started coming when he was older, allowing him more productive seasons. Ultimately, steroids helped players heal quicker and extend their careers. There were many negatives to the steroid era however. The records that were…

Freshwater creek is a freshwater stream located in North Cairns, and flows through the Redlynch area-which consists of rainforest, housing, farming and recreational areas. In order to have an indication of general health levels for Freshwater creek, measurements of the water parameters must be regularly checked. This is done to maintain health and prevent abnormal water qualities. Certain water qualities like dissolved nitrates, ammonia and oxygen will be measured at a site upstream from…

intermolecular forces regarding hydrogen bonds, London Dispersion forces, as well as Dipole-Dipole, and simple ionic bonds in the case of sodium chloride. The molecule with the least amount of these forces is the one with the weakest bonds,…

1. INTRODUCTION Graphene consists of single layer of carbon atoms arranged in a hexagonal lattice. It is the basic structural element of many other forms of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes. In simple terms, graphene, is a thin layer of pure carbon bonded together in a hexagonal honeycomb lattice. It is the thinnest compound known to man, the lightest material known, the strongest compound discovered, the best conductor of heat at room temperature and also the…

Macromolecules are large molecules that are composed of smaller units. The four major macromolecules are carbohydrates, lipids, nucleic acids, and proteins. Carbon is the primary component of the four macromolecules. Carbon's molecular structure allows it to bond in many different ways and with many different elements. A Monomer is an atom or small molecule that may bind chemically to other monomers to form a Polymer Different monomers make up a polymer. Polymers combine to make a molecule, and…

31. cis/trans isomers Isomers are compounds with a similar substance recipe however extraordinary structures. The structures of these isomers vary in the introduction of the two chloride particles around the Co3+ particle. In the trans isomer, the chlorides involve positions opposite each other in the octahedron. In the cis isomer, they possess contiguous positions. The distinction amongst cis and trans isomers can be recollected by taking note of that the prefix trans is utilized to portray…

• Omega-3 fatty acids have the first double bond on the third carbon counting from the carbon in the methyl end. These are essential fatty acids (our body can’t produce them). Alpha-linolenic is an example of omega-3 fatty acid. • Omega-6 fatty acids have the first double bond on the sixth carbon counting from the carbon in the methyl end. These are essential fatty acids, because our body cannot produce…

The Nanotube Introduction: Nanotubes, specifically the carbon nanotubes are just one of the handful of structures engineers and scientist use today that fall in the nanoscale category. Structures in the nanoscale category are usually between 1-100 nanometers, which one nanometer is one-billionth the size of a meter. A confusing yet beneficial property found in materials at the nanoscale is a concept call quantum called quantum mechanics. In quantum mechanics the laws of classic or Newtonian…

bonding 5.What are all the types of chemical bonds? Ionic, Covalent, and Metallic bonding. 6.What do you call an element that has different forms . Isotopes 7.Which type of bonding is the “strongest”? Ionic bonding 8.True or False: Ionic bonds are formed from metal and neutral atoms. 9.True or False: Covalent bonds are NOT made from neutral and neutral atoms. 10.How does a covalent bond form? From nonmetal and nonmetal atoms. 11.True or False: Metallic bonds can be formed by metal and neutral…

Cassamajor, Kimberly P1 R1 S4 Science Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the…
