. Our predictions were not supported by our data. We predicted Hexane to not mix well with the other liquids, due to the fact that is a nonpolar substance. When in fact it mixed with all but two substances , Methanol and Water. I believe this to be for the fact that both Methanol and water have strong properties of hydrogen bonding. While we thought water wouldn't mix , we predicted Dichloromethane , n-Pentanol,Methanol,Toulene and Water to mix. Again our predictions were not exact in that…
Beta-decay spectroscopy of the neutron-rich rare-earth nuclei Introduction Neutron-rich nuclei in rare-earth region are the most collective nuclei in nature since their protons and neutrons are lying far away from the shell closure limit, which proton shell closure are Z=50 and Z=82, and neutron shell closure are N=82 and N=126[1]. For example, the doubly mid-shell nucleus 170Dy[1] which has proton number Z=66 and neutron number N=104 is considered as the most collective in that region. Until…
August 30, 1871, in Spring Grove, New Zealand. He was a pioneer of nuclear physics and the first to split an atom. He was awarded a Nobel Prize in chemistry for his theory of the atomic structure. He discovered alpha and beta rays, that the atom could be split, and contributed to the Atomic Theory. He used the gold foil to see how to alpha and beta rays would bounce off off different atoms. Ernest was responsible for a remarkable series of discoveries in the fields of radioactivity and nuclear…
under controlled conditions. He identified many different laws, postulates, etc. One of which were his four postulates over the atom. John Dalton’s Postulates include: Atoms are small, indivisible particles that make up matter Every atom of a certain element are always identical in mass and properties Atoms can not be destroyed, created, or changed into other types of atoms during chemical reactions, they may only be…
Benzene, rings are very prevalent in many products that are used on a daily biases by humans, and compounds that contain benzene are often referred to as being aromatic. Benzene has characteristics that differ from many compounds causing it to react differently when mixed with certain compounds. Although benzene has three double bonds, it does not react like a normal alkene in terms of addition reactions. For example, when bromine reacts with a simple carbon-carbon double bond it forms dibromo.…
How Does CoQ10 work? What is it? Before you can understand how Coenzyme Q10 (CoQ10) works, you need to know the basics about the substance. 1) It is found within almost every cell of your body. 2) It is naturally produced and synthesized by your body 3) It has two forms; ubiquinol (active) and ubiquinone (oxidized) 4) It is found in higher concentrations in your organs, including your heart, kidneys, and liver How does it work? 1) It generates power, or energy inside your cells to boost energy…
The results collected illustrate that cyclohexene is the unknown. Comparing the measured boiling point of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.3°C. Comparing the measured density of cyclohexene to the literature value of cyclohexane, there is only a difference of 0.027 g/mL difference and comparing measured refractive index of cyclohexene to the literature value of cyclohexane, there is only a .009 difference. All of these results shows that both…
construct the atom. Niels contributed to the atomic structure and quantum theory. He received the Nobel Prize in Physics in 1922 for his work. Bohr was a physicist, philosopher, and a promoter of scientific research. Bohr’s proposal stated that the electron revolve in a stable orbit around the nucleus and that the energy levels in which the electrons are on are discrete. Bohr was the very first scientist to discover the electrons travel separately in energy levels. Bohr stated that an atom would…
I am researching the element, boron. The symbol of boron is a just a capital B. The atomic number of boron is 5. Boron’s mass is 10.811 grams. Boron has 5 protons, 6 neutrons, and 5 electrons. The Periodic Table lists elements in numerical order from the smallest atomic number to the largest atomic number. That is why boron is the 5th element on the Periodic Table. It comes after beryllium and before carbon. Boron was discovered on June 30th in 1808. It was discovered by French chemists,…
1. Describe the structure of an atom, including the subatomic particles, their charges, and their location. An atom is made up of subatomic particles called protons, neutrons, and electrons. The protons carry a positive charge found in the nucleus; neutrons carry no electrical charge and are also found in the nucleus. Electrons carry a negative charge and orbit around the nucleus. 2. Name five characteristics of water and relate them to the structure of water. Water has a high heat capacity…
