Cell Respiration Lab Research Question What is the optimal temperature for germinating pea-seeds where the rate of respiration is the greatest? Background Information Cell Respiration refers to the biochemical process conducted by the cells of an organism that combines glucose and oxygen to produce energy in the form of ATP, along with two by-products, water and carbon dioxide. The equation representing this chemical reaction is shown below. C6H12O6 + 6 O2 6 CO2 + 6 H2O + ATP Although plants and

discussed are about; the study of charging by friction, induction and conduction. The material being used to demonstrate the study in this lab are: Pith ball electroscope, ebonite rod, glass rod, wool and plastic. The lab also talk about the law of Electrostatic in the table # 1 as the procedure of charging the ebonite rod with the wool and plastic with the glass rod then looking at how the charge affect the pith ball as toward the charge ( attract or repel ). The safety concerns that are likely to occur

reality with his invention of the Electrostatic Machine. The Electrostatic Machine laid the groundwork for understanding electricity and magnetism in depth. In the 1600’s, philosophers, scientists, and instrument makers created many devices to generate electrostatic charges, but was never to the full extent and paused with only their charges. Although, incomplete machines date back from 1750 and appear to have been Benjamin Franklin’s very own design of the Electrostatic Machine. The idea of electricity

be multilayer in nature, and it can create an excess of adsorbed water in comparison with the concentration of water in the eluent. HILIC separation involves not only partition but also hydrogen donor interactions between neutral species, weak electrostatic interactions when the high organic solvents are used and dipole-dipole interactions

in types 2 and 3. The H–O bonds show red shifts with complex formation in types 1 and 2, in which they are more considerable for type 1 complexes. The O–Y bonds display red shifts in the type 3 and blue shift in the type 2 complexes. Molecular electrostatic potential (MEP), quantum theory of atoms in molecules (QTAIM)

After the discovery of the atom humans have formulated nuclear technologies to efficiently produce power. However, as with any new technology there comes the advantages and disadvantages thus leading to a never–ending debate. Nuclear power is a source of energy that is created through the fission of atoms in a nuclear plant or reactor. The nuclear energy is present within the nucleus of the atom and when radioactive atoms are split in nuclear fission processes or combined during fusion then the energy

At long distances, two nuclei repel each other due to the positive protons and the electrostatic force. However, if two nuclei were to be brought close enough the electrostatic repulsion can be overcome by the attractive force of the nuclear force, which becomes stronger at nearer distances. In the diagram below, the electrostatic force between the positively charged nuclei is repulsive, but when the separation is small enough, the attractive nuclear forces

All elements are made of atoms, but it is the structure and arrangement of these atoms which determine the specific element, isotope and state. Each atoms is comprised protons, neutrons and electrons. The protons and the neutrons form the nucleus of the atom whilst the electrons orbit this nucleus in ‘shells’. The number of protons determine the element, the neutrons the isotope, and the electrons the charge. These atoms can be bonded together in one of three ways. Either metallic, ionic or covalent

The bond is usually between a metal and a non-metal element. Atoms in a covalent bond are held together by electrostatic forces of attraction between a positively charged nuclei and negatively charged shared electrons. Every atom has a different structure or shape. The shape of an atom can change depending on the number electrons. A tetrahedral atom is in a pyramidal

In science, an ionic compound is a concoction compound made out of particles held together by electrostatic powers named ionic holding. The compound is unbiased by and large, yet comprises of emphatically charged particles called cations and adversely charged particles called anions. These can be basic particles, for example, the sodium (Na+) and chloride (Cl−) in sodium chloride, or polyatomic species, for example, the ammonium (NH+ 4) and carbonate (CO2− 3) particles in ammonium carbonate. Singular

obtained electrode is called ChiTNP-CPE/DNA.To evaluate the DNA immobilization on the electrode surface,the study of cyclic voltammetry[Fe(CN)6]3-/4- redox couple was performed at the presence and absence of DNA.The work is based on the large electrostatic repulsion between this redox couple and the negatively charged DNA [22]. For this purpose, cyclic voltammograms (CVs) of 20 mL of a solution containing 0.05 M [Fe(CN)6]4− and 0.5 M KClwere performed on the surface of bare CPE, ChiTNP-CPE, and ChiTNP-CPE/DNA

During the 1800s, physicians practiced various medical techniques, such as homeopathy and herbalism, while some physicians invented new techniques, like Electrotherapy. In the early 1800s, physicians relied on the "heroic" medicines for their medical treatments. Physicians classified the "heroic" medicines as treatments that would clean impurities from the body like purgation or bleeding by cup or by leech. For the people and physicians who did not agree with the "heroic" medicine, the development

as a result, the ion that loses electrons becomes the cation while the ion that gains electrons becomes anion. In NaCl, sodium gains a positive charge, forming Na+, at the same time, chlorine gains a negative charge, forming Cl—. Lastly, the electrostatic

Ever since Einstein first penned his famous equation, E = mc2, showing the world that there is energy stored in matter waiting to be harvested, mankind has been searching for new ways to free it. Initial work towards this goal led to the development of nuclear fission, the pinnacle of which was the successful Trinity Test in 1945. As time went on the technology was improved upon, resulting in nuclear power plants and more powerful weapons. Still, there was a desire for a more efficient, less dangerous

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

Most of us Americans wonder who was part of the Gemini 4. Gemini 4 was the secoud crewed mission of the Gemini series. The mission included the first American spacewalk. The experiments performed during the mission were electrostatic charge. James McDivitt and Ed White where the two astronauts part of the a Gemini. Ed White was the first American to walk in space. White was born on Noverber 14, 1930, in San Antonio, Texas. White went to school at United States Military Academy and University of

the valence electrons are found in the molecules. As the valence electrons determine the chemical properties of the molecule, based on the properties of the molecule we can determine the type of bonding it falls under. The bond is formed by the electrostatic force of attraction between either the electrons or nuclei of the molecules. There are two categories of chemical bonds, Primary bonds and Secondary Bonds. Primary bonding has to occur before

transmission out the electrostatic force from the armrest and also from the backrest. The quality of the entertainment depends on the quantity of emotional being aroused. [FUKUSHIMA]. The people often seeks for more intense of fearful emotion, so, the chilly chair one of the device that can be used. This kind of chair can be used in the home theatre too. Commonly, the piloerection occur due to the cold atmospheres, however, the chilly chair causing the emotional feeling through the electrostatic force that

Task 1 (P1) The periodic table is laid out into groups and periods. They are also put into different blocks S-Block, D-Block, P-block and F-Block due to their energy levels. They are organised by their energy levels and chemicals properties. As the elements go along the periods in the periodic table the electronegativity increases but as the elements go down the groups the electronegativity decreases. Ionizing energy also increases as the elements go across the periods and also decreases when the
