Lab 3: Hydrogen Spectrum Abstract When white light is viewed through a diffraction grating‚ we can see each component that makes up the light. However‚ when in an excited state‚ a gaseous element produces bright light of specific wavelengths rather than a continuous spectrum of colors. This phenomenon ultimately lead to the Neils Bohr model of the atom in 1913. Introduction In the middle of the 19th century‚ Robert Bunsen and Gustav Kichoff observed that gases emit spectral lines specific

zinc granules react fairly slowly with dilute hydrochloric acid‚ but much faster if the acid is concentrated. The catalytic decomposition of hydrogen peroxide Solid manganese(IV) oxide is often used as a catalyst in this reaction. Oxygen is given off much faster if the hydrogen peroxide is concentrated than if it is dilute. The reaction between sodium thiosulphate solution and hydrochloric acid This is a

Introduction: In liver cells‚ hydrogen peroxide is produced as a bi-product of some metabolic reactions. Hydrogen peroxide is a highly active chemical used in household products for bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

Chemist from the University of Glasgow in Scotland have taken a step closer towards producing clean hydrogen fuel in a maintainable way. Hydrogen gas is able to be burned to generate electricity without producing lethal releases‚ unlike fossil fuels. It is produced from water releasing them as gas‚ through a process called electrolysis‚ which uses electricity to break the bonds between hydrogen and oxygen. This technique is 30 times faster than the current method‚ and can be powered by renewable

OF CATALASE ON HYDROGEN PEROXIDE The aim of the experiments is to see if increasing the surface area of the enzyme Catalase‚ affects the relative activity of the substrate Hydrogen peroxide. Then to observe and measure the effect the Catalase has on the chemical breakdown of the hydrogen peroxide. My theory is if you keep increasing the surface area of Catalase‚ the more active sites are available to join with the substrate causing an increase in the breakdown of the hydrogen peroxide producing

The North Korean state media released an official statement in December declaring a new weapon of mass destruction has been added to their arsenal: the Hydrogen bomb. In a statement released by a North Korean news agency on Tuesday‚ it was made clear that “the regime’s scientists are in high spirits to detonate H-bombs‚ capable of wiping out the whole territory of the US at once” (Vale). The testing of their alleged H-bomb was said to have occurred last Wednesday. Does North Korea have the right

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

believe that if the amount of sodium citrate is too low or too high‚ the sodium alginate solution would not form into a ball. The recommended amount of sodium citrate to be added to the sodium alginate solution was ⅛ teaspoon‚ or 0.5 grams. We supposed that if we exceeded this measurement‚ the sodium citrate would unbalance the whole solution‚ making the balls deform. If we added too little of the sodium citrate‚ we thought that there would be too little for the sodium citrate to fully do its job of
