Types of bottom paints SPC (Self polishing copolymers). It contains a resin known as SPC Copolymer. The chemical substance reacts with salt water and the result is the discharge of biocides in the entire life span of the bottom paint. The reaction takes place at any circumstance provided the vessel is in contact with salt water. Controlled Solubility Copolymers These types of bottom paints are partly soluble in water meaning it wears down when water passes across the exterior of the

Introduction Catalysts help speed up reactions. Catalysts come from a certain molecular substance found in cells. These are called enzymes. Enzymes would temporarily bond to one or more reactants of a reaction and catalyze, meaning they speed up the process with lower activation energy needed. Enzymes provide a variety of functions such as cells using an enzyme to rid themselves of a poisonous substance (hydrogen peroxide) and also energy usage. catalase 2H2O(l) ( 2H2O(l)

Chemical Reaction Placed a small amount of Zinc Powder in a small test tube. Added about 20 drops of copper (II) sulfate solution. Allowed the reaction to take place and recorded result at the end of the laboratory period. Placed a strip of magnesium in a

rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department, 2011). In chemical reactions bonds must be broken and new bonds must be formed. In order for this to occur the bonds must be made less stable. For bonds to become less stable a small input of energy is required and this is called the activation energy. In simpler terms, in order for a reaction to begin and proceed spontaneously a small input energy is required to give the reaction a push

DESIGN Aspect 1: Problem: The problem is will there be a chemical reaction taken place that is able to be observed. Variables: Manipulated: The different chemicals we use for each reaction. Responding: The observation of the chemical properties to see if a new chemical has been formed while the reaction is taking place. Controlled: The surface area of the calcium solid, the volume of chemicals, and the intensity of the flame from the Bunsen burner. Aspect 2:

R-value printed on exam if you switched DG and DH (since DH not labeled correctly) (4) In the absence of a selective catalyst, the synthesis of methanol can be accompanied by a side reaction in which coke (solid carbon) is formed (see below). If 1 mol CO and 2 mol H2 are fed to a reactor at 298 K and 0.5 bar, approximately how many moles of coke will form? CO(g) + 2H2(g) ( CH3OH(g) 2CO(g) ( CO2(g) + C(s) Compound
