Task 1b Practical analysis The products of the practical were typical for an acid-base titration with carbonate, which are sodium chloride, carbon dioxide and water. The balanced equation for the practical is Na2CO3 + 2HCl = 2NaCl + CO2 +H2O. This is because the as you add the hydrochloric acid to the sodium carbonate the chlorine displaces the carbon and oxygen which then becomes carbon dioxide and water with the lone hydrogen. Ionic bonding is when a metal gives an electron(s) to a non-metal

catalase has been raised because more particles have been exposed to the other reactant, which lead to a higher rate of collision between the particles of reactants. Thus, there’s a higher chance to gain the activation energy in order to carry out chemical reaction. Rate of reaction increased. Catalase was a biological catalyst (enzyme) which made of protein and will denature in high temperature due to the breakage of bond between molecule. In this case, boiling the liver will cause the enzyme inside

division of DuPont that produced paint for the auto and trucking industries. From the beginning of Kullman’s term as CEO in January 2009, she sought to transition the Company from an economically struggling commodity chemical business (with a 2009 stock price below $19) to a specialty chemical and science-driven business (Exhibit ). Kullman believed DuPont was best positioned for a future at the core of industrial biotechnology by competing in agriculture, nutrition, and advanced materials, areas with

Molecular Structures Molecular Structures Learning Objectives: - Understand covalent bonding displayed by elements in biological systems - Apply the octet rule - Practice converting molecular formulas into molecular structures - Be able to visualize and draw three dimensional molecular shapes Introduction: The octet rule states that most elements will share or exchange valence electrons in order to achieve a similar electron arrangement to the nearest noble gas. This concept is extremely
