  • Case Study: Electron Motion Control And Imaging

    Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all microscopic motions outside the atomic core and radically change our insight into the workings of the microcosm, which will improve our understanding of chemistry. Moreover, sometimes revealing the electron dynamics by time-resolved spectroscopy measurements…

  • Chickpea Experiment

    Since the NaCl compound has a molecular weight of 58.44 g/mol and water has a molecular mass of 18.01 g/mol, this shows that NaCl is a bigger molecule. The chickpeas surface undergoes osmosis, allowing for water and/or salt to move from a higher concentration in the surroundings to a lower concentration into the chickpea. Due to the size of the salt molecule, the chickpea will take in less NaCl molecules compared to water molecules to occupy the same space in the chickpea. Figure 2 is a graph of…

  • Structure Of Water

    carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has six valence electrons in its outer shell and acts as the central atom. Two of these electrons is shared with the two hydrogen atoms which have one valance electron each in their outer shell giving a chemical formula of H2O. This shared pair helps to fill…

  • Water Quality Lab Report

    with the neighbouring molecule for them to bond. A covalent bond only occurs between two non-metals, the molecules share electrons to achieve full valence shells for the molecule to be stable. In the case of water the two hydrogens and one oxygen share electrons to get the hydrogen molecules with two electrons in their outer shells and…

  • Why Is Water Unique

    water and many animals would no longer exist. Without water the human body would only be able to last only three days. The reason that water is so unique is because of its molecular structure. Due to the fact that it is a polar covalent molecule it has very little positive and even smaller chances of a negative charge on opposite ends. Also because is called “a bent” which is basically a polar molecule, it contains a real important characteristic of what is built and formed when lots of water…

  • Four Intermolecular Forces

    The structure of a molecule affects how it is able to bond with other molecules and how effective these bonds are. The structure of the molecule itself is held together by the intramolecular forces, which are the internal forces of a molecule, such as the attraction and repulsion of electrons to the protons in the nucleus. The external forces on a molecule, which are called the intermolecular forces, such as electronegativity, help to determine the boiling and melting points of each element.…

  • Stereochemistry Synthesis

    Introduction Stereochemistry alludes to the science that reviews the properties of stereoisomers. It can likewise be characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary…

  • What Happen If A Person Touch Liquid Nitrogen Avoiding The Atomic Repulsion?

    think that. How does this make you feel? Normal, I do not really feel bad for that, technically nothing changes. In other words, I just know more about something that was all the time there. If you could touch something, what would you touch? Water, if for instance the atoms repulsion affect the textures of the objects, I really curios which is the real texture of the water. How do you think it would feel? I think it will feel similar, but with more density. This could be similar like…

  • Characteristics Of Intermolecular Forces

    Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

  • Asymmetric Synthesis Research Paper

    According to R.A Aitken, “An asymmetric synthesis may be defined as a synthesis in which an achiral unit is an ensemble of substrate molecules is converted to a chiral unit such that the possible stereoisomers are formed in unequal amounts.” It relates to any synthetic process that incorporates one or more new elements of chirality during a functional group transformation. Asymmetric synthesis involves the formation of chiral molecules. An object is said to be chiral, if it cannot be…
