  • Acid Base Neutralization Lab Report

    1001 Words  | 5 Pages

    Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter. Its pH is

  • Polar Bears: Thick Layer Bear

    1254 Words  | 6 Pages

    Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called

    class of reactions. These reactions can occur by a range of mechanisms, the two studied in this lab are the SN1 and SN2 reactions. In a nucleophilic substitution, the nucleophile is a electron rich chemical species which attacks the positive charge of an atom to replace a leaving group. Since nucleophiles donate electrons, they are defined as Lewis bases. The positive or partially positive atom is referred to as an electrophile. The whole molecule which the electrophile and the leaving group are part

  • Essay On Aromaticity

    746 Words  | 3 Pages

    Aromaticity can be termed as a chemical property of conjugated cycloalkenes. Aromaticity deals with the uncommon stability of benzene and its derivatives, which is caused by the ability of the electrons in the p-orbitals to delocalize and act as a framework to generate planar molecules. A molecule is only considered aromatic due to the fact that it is cyclic, that it follows the Huckel’s Rule and lastly that each element must have a p-orbital. Antioxidants play and important role in health. It can

It displays that Na has one valence electron. In order

  • Lithium Atomic Structure

    1751 Words  | 8 Pages

    In the periodic table lithium’s atomic number is 3. The atomic number describes the number of protons in the nucleus and the number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized. The protons and neutrons together form the nucleus. Lithium has 3 protons and usually 4 neutrons since its atomic weight is 6.9 according to the periodic table

  • Atomic Theory Research Paper

    Initiated by Democritus’s introduction to the concept of atom, Dalton proposal of the Atomic Theory, and Thomson proof of the existence of electrons. In addition, the mass and charge of electrons investigated by Millikan and the location of the nucleus and electron brought to attention by Rutherford. Finally, the neutron’s existence proven by Chadwick and the electron shells made known by Bohr. Similar to the modern atomic theory, alternating scientific concepts encourage the proposal of new ideas and

    The graphical illustration of the representative configurations under consideration is depicted in Figure 2. Possible interactions which considered for HOY molecules with HC3OX are including hydrogen bonding (O···H) and halogen bonding (X···Y,O···X) which have been denoted as XYm. The X is representing the

  • Free Radical Inorganics

    In contrast, a substance that donates electrons is a reductant or reducing agent (Cao G, Prior RL, 1998). In general, a chemical reaction in which a substance gains electrons is defined as a reduction (SchaferFQ, BuettnerGR, 2001). Oxidation is a process in which a loss of electrons occurs. When a reductant donates its electrons, it causes another substance to be reduced, and, when an oxidant accepts electrons, it causes another substance to be oxidized (Hrbac J, Kohen R,

    and Its boiling point is 613.0 °C. Arsenic has a rhombohedral crystal structure, and it is usually found in a solid form while on earth. This element is found in group 15, p-block, on the periodic table, and Its period is period 4. Its electron configuration is [Ar] 4s2 3d10 4p3. B stands for beauty because, in The 1800’s arsenic was a huge beauty statement in Europe. It was originally found in Styria (

  • Pros And Cons Of Halogen Bonding

    2221 Words  | 9 Pages

    Halogen bonding, XB, is the product of a non-covalent interaction between a halogen X and a negative site B (e.g., Lewis base). The halogen, X, is usually part of an R-X molecule where R can be another halogen, an organic or an inorganic electron-donating-group. Halogen bonding (XB) is in some ways analogous to hydrogen bonding (HB). In the latter, a hydrogen atom is shared between an atom, group or molecule that “donates” and another that “accepts” it.[1-3] In halogen bonding, it is a halogen atom

    the center of the gold atom” (Tretkoff, Ernie). This discovery is so important because protons are what define what element an atom is. Bohr also used that discovery to find that electrons travel in orbits around the nucleus. Rutherford’s model is called the “solar system model” because in his model because the electrons orbit the nucleus almost like they are like planets orbiting the sun. Rutherford paved the way for the modern model of the atom. He also theorized the existence of the neutron which

    The mural on the radio city had a central section that showed a large hand holding a sphere emerging from an ambiguous machine (Linsey 50). These features explore the major theme of the art that of the interrelationship between the biological and the physical world (Linsey 50). The mural also depicts a clear bolt of lightning being captured by electrical equipment. These images have a common source in mass culture history, that of real scientific experiments (Linsey 50). The features in the mural

  • Essay On Electromagnetism

    1345 Words  | 6 Pages

    What is electromagnetism? Merriam-Webster states that “electromagnetism is magnetism developed by a current of electricity.” An alternative definition suggests that electromagnetism is a fundamental physical force that is responsible for interactions between charged particles which occur because of their charge. To fully understand how electromagnetism affects us, it is important to understand the basic foundation of electromagnetism. The field of electromagnetism was only six years old when Henry

  • Tetrahedral Distortion Lab Report

    1010 Words  | 5 Pages

    Tetrahedral distortion is defined as the change in both the distance of bond and angle of bond are present. The degree of distortion with respect to the beta phase can be related to the tetrahedral tilt angle and the intertetrahedral bridging angle. While for tetrahedral tilting, there is only change in the angle of the bond and no change in bond distance. When there is an increase in temperature, the Fe-O-P bridging angles increases and the tetrahedral tilt angles decreases. As the temperature increases

    Have you ever wondered if time travel is possible? If so how would you use it? Space travel has been a question to many astronomers from around the world. According to space.com”We cannot avoid moving into our futures, but we can control the rate that we move through time.” So this is saying that space travel is possible we encounter it daily and it is possible to manipulate it. Overall time traveling would be a huge advantage. It would give us the ability to change our history, save important historical
