The Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas‚ which means that when the glowing splint is inserted into the test tube‚ the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added‚ this will increase the rate of the production of oxygen in the reaction‚ without affecting the state of the manganese oxide. Materials: Test tube Retort stand Bunsen burner Scoopula Flint sparker 2cm of potassium

Hydrogen Summary * This is how hydrogen fuel cells work: 1. Gas stored in tanks 2. Atoms reach anode 3. Become hydrogen ion and a free electron 4. Ion goes through electrolyte layer 5. Hydrogen ion passes‚ but free electron does not 6. Free electron runs through external circuit from anode (-) to cathode (+) 7. Current of electrons creates electricity 8. Hydrogen ion enters cathode and combines with oxygen to become water which is better for the ecosystem because

bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war‚ the U.S wanted something bigger and stronger. In 1950‚ President Harry S. Truman announced work on the hydrogen bomb. A group of scientists led by Edward Teller created the first hydrogen bomb in

Functional Decomposition Diagram An analyst first must understand an organization’s business functions before he or she can begin developing information systems. The functional decomposition diagram (FDD) is a business planning tool that depicts the hierarchy of business functions‚ processes‚ and subprocesses within an organization that are later described in detail using process models (chapter 6). The exercise of breaking down‚ or decomposing‚ the business functions into processes makes complex

Looking back at the research question‚ the actual amount of reactant did not match the theoretical stoichiometric amounts according to the balanced equation‚ but the amount of catalyst matched the original value when uncertainty is taken into account. The percent yields for the reactants in the equation are very far from 100% yield. In the case of water‚ the percent yield came out to be meaning there were at least 2 times to 4 times more water than there should be. The percent yield of oxygen came

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

<b>Thesis Statement</b><br>The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb‚ which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.<br><br><b>The Hydrogen Bomb</b><br>The Atomic Bomb Was A Essential

molecules be exposed to hydrogen peroxide. This will result in the rate of reaction increasing because it increases the chance of more successful collisions between the enzyme and the substrate. Catalase is an enzyme found in food such as‚ potato. It is used to break down a poisonous by-product of metabolism called hydrogen peroxide. Hydrogen peroxide is a compound that can kill cells therefore; it is essential that our body can break it up. Catalase breaks down hydrogen peroxide into oxygen and water

A plot of against gives a straight line. Example 4 The Arrhenius parameters which define the Arrhenius equation for the decomposition of cyclobutane are In (A/s-1) = 15.6 and Ea = 261 kJ mol-1. Determine the half-life of cyclobutane at the temperature of 773 K. C4H8 (g) 2 C2H4 (g) The decomposition of cyclobutane follows first order kinetics as the unit of A is s-1. Comment: The units for A provide information on the reaction’s overall order of kinetics
