Gas is an important productive resource in the world. Driving cars‚ heating buildings‚ producing electricity‚ people all need gas. Therefore‚ gas is directly related to people’s normal life and the global economy. Recently‚ due to the fights between Israel and the Hezbollah guerrilla‚ the Middle East political and economic situation has been deteriorating‚ which has led to the continuous hikes of gas prices. Since gas plays an important role in our economy‚ people should understand that the high

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

Apportionment Using the Hamilton Method Dawn Ambrose Argosy University- On-line MAT109 A01 Instructor: Marcus Vandiver Apportionment Using the Hamilton Method Using the Hamilton method of apportionment‚ determine the number of seats each state should receive. Using the numbers you just calculated from applying the Hamilton method‚ determine the average constituency for each state. Explain your decision making process for allocating the remaining seats. As can be seen in the chart above

Lab #3: Method of Initial Rates: Iodine Clock Introduction The detailed system of steps in a reaction is called the reaction mechanism‚ and it is one of the principal aims of chemical kinetics to obtain information to aid in the elucidation of these mechanisms in order to better understand chemical processes. Reactions usually occur in a stepwise manner with each step proceeding at a different speed. If the rate of reaction is slow enough to measure‚ this is indicative of a step much slower

A phase transfer catalyst or PTC in chemistry is a catalyst which facilitates the migration of a reactant in a heterogeneous system from one phase into another phase where reaction can take place. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase unless the phase transfer catalyst is present. Phase transfer catalysis (also PTC) refers to the acceleration of the reaction by the phase transfer catalyst. Phase transfer catalysts for anion reactants are often

Greenhouse Gas The greenhouse gas effect is the number one blame for global warming. We could not live without the greenhouse effect. The main gases are ozone‚ nitrous oxide‚ carbon dioxide‚ methane‚ and water vapor. These reflected rays‚ called infrared radiation ‚ keeps the atmosphere warm. They are vital in maintaining the balance in our atmosphere. The greenhouse effect is mostly a result of the sunlight’s energy and the clouds that absorb and reflect heat. Without the greenhouse effect‚ earth

Effects of Computer Use on High School Students’ Sense of Community MERVYN J. WIGHTING Regent University‚ Virginia ABSTRACT The author used a mixed-method design to determine whether and how use of computers in the classroom affects sense of learning in a community among high school students (N = 181). The results indicate that using computers in the classroom positively affects students’ sense of learning in a community. Analyses revealed that students believed that connectedness with their
