of chemical bonds? Valence electrons are the electrons that are on the outermost shell of the atom’s electrons which are can be either given away‚ added‚ or to be shared. When these electrons are given away‚ added to or shared‚ there is a chemical change occurring and the compound that is formed is changed from the original elements. This is called bonding which is pretty much the realm of the electrons. It is the sharing of electrons from each atom that define the chemical bond. Because all

In my coursework I will investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying

For the alkanes‚ which are non-polar hydrocarbons‚ the intermolecular forces are induced dipole forces. In the case of the alcohols‚ the intermolecular forces include induced dipole forces‚ dipole forces‚ and hydrogen bonding. Induced dipole forces increase with

Sheet. 3 hydrogen bond interactions between an amide and oxygen group were identified. The 3 sets of residues that hydrogen bonds were formed between were identified and shown below in Figure 2. Bond distances and bond angles were identified. (Bond distance – Coloured blue‚ Bond angle – Coloured yellow) Figure 2.

a neutral aqueous solution‚ five molecules of water are bonded together by weak hydrogen bonds. Furthermore‚ due to the electronegativity of oxygen‚ water is a polar molecule. Due to its polarity‚ water is classified as the universal solvent. You will investigate the life-sustaining properties of water throughout this lab. Part One: Polarity Label the diagram of water below. Make sure you label the oxygen‚ hydrogen atoms as well as the partial charges which creates waterʼs polarity. 31927802603500

Two things that comes to mind whenever people say the name Barry Bonds is the most homeruns ever hit in a players major league career and the use of steroids. As we all know or at least should know Barry Bonds is the all-time leader in homeruns with 762 in his career. It only took Bonds 22 years to hit those 762. Most players are luck to hit 500 in that amount of time. Questions began to rise when Bonds was not only breaking records but putting stats up such as. Although 1998 belonged

of the entire human body. The body can get around 20% of its water needs through food but the rest must come from drinking fluids. The human body is mainly constituted of just 4 elements‚ carbon‚ hydrogen‚ nitrogen and oxygen but it is the combination of one oxygen atom covalently bonded with two hydrogen atoms and its unique properties that make this tasteless‚ colourless and odourless liquid that make it crucial in the makeup and functioning of the human body. Water is often overlooked as a key
