    Introduction The hydrogen fuel cell is device that generates electricity by a chemical reaction. It combines hydrogen and oxygen to produce electricity, heat, and water. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes and charged particles are carried from one electrode to another through the use of an electrolyte. Much of the hydrogen and oxygen used in generating

    negative poles by what amounts to static electricity. This electrostatic attraction is termed a hydrogen bond. It is about 20 times weaker than the H – O bonds within any one water molecule, but still gives rise to considerable, transient adhesion, which packs the water molecules closely together in the liquid state. In contrast, as the temperature falls below about 4 ° C and ice begins to form, the hydrogen bonds between the molecules become longer lived. They eventually settle into a rigid, rather

  • Hydrogen Sulfide Lab Report

    1405 Words  | 6 Pages

    Hydrogen Sulfide undergoes covalent bonding – where two or more non-metal atoms are held together by one or more shared pairs of valence electrons. The atoms forming a covalent bond must have a relatively equal attraction for electrons (electronegativity). Hydrogen has an electronegativity of 2.2 and sulfur of 2.58. Covalent bonds tend to also have low melting and boiling points due to weak intermolecular forces which break down quite easily (BBC, 2014). Substances that are bonded covalently are

    that pertained to the enzyme known as catalase, which converts hydrogen peroxide into oxygen. Due to peroxide being toxic to the tissues of both plants and animals, both possess the enzyme catalase, which breaks into two non-toxic compounds: water and oxygen gas. Enzymes are proteins that react to certain substrates to create a product, and continue doing so afterwards. Methods and Materials To test reactions between catalase and hydrogen peroxide, groups of three to four people were formed. A scale

    reaction rate between catalase and H2O2 Figure 1 shows that the optimum temperature for catalase to catalyze hydrogen peroxide is around room temperature (30℃) as it has a very fast reaction rate (5). The overall trend is that temperatures that differ from 30℃, will decrease the reaction rate. Discussion This experiment supported the hypothesis, since catalase was the most effective with hydrogen peroxide when it was in an environment with a temperature of 30℃. It was expected that an extreme temperature

    type or different, these atoms are joined with chemical bonds which is a result of either sharing or exchanging electrons. √ There are four main types of chemical bonds by joins molecules together: ionic bonds, covalent bonds, polar bonds as well as hydrogen bonds. Ionic bonds involve the transfer of one electron from one atom to another giving rise to a positive atom (Cation) and the gaining atom becoming negative (Anion). For example, a sodium atom giving an electron to chloride atom to give rise
