Matthew Rose Mr. Schwartz Chemistry 8 March 2011 Ernest Rutherford Ernest Rutherford was one of the most famous physicists of the early 20th century. He won the Nobel Prize in chemistry in 1908 for his work on atomic emissions and his contributions that led to the discovery of atomic fission. Ernest Rutherford was born in Nelson‚ New Zealand on August 30‚ 1871. His father was James Rutherford and his Mother was Martha Thompson. His father was a wheelwright‚ a person who builds and repairs

reaction. In 1889‚ Svante Arrhenius demonstrated that the rate constant k is related to the temperature of the system by what is known as the Arrhenius equation: k=A where R is the ideal gas constant [8.314 J/(mol oK)]‚ T is the temperature in degrees Kelvin‚ Ea is the activation energy in joules per mol‚ and A is a constant called the frequency factor‚ which is related to the fraction of collisions between reactants having the

Be it Resolved that…tactical nuclear weapons could have been justified in the Korean War. Remember that two arguments per side must be based on scientific research and two arguments based on geopolitics or moral arguments Affirmative 1. Pillar: North Koreans today would not be deprived of social freedom under the ruling of Kim Jong-un if nuclear weapons were to be dropped in the Korean War. a. Evidence: Those who have evidenced the average lifestyle in North Korea say that life is extremely difficult

Chem Final Exam Combination Combination reactions‚ also known as synthesis reactions‚ involve the combination of two or more substances into a single new substance: A + B ---> AB Many metal oxides‚ for example‚ absorb carbon dioxide (CO2) from the air to form carbonates: CaO(s) + CO2(g) ---> CaCO3(s) Decomposition Decomposition reactions represent the reverse of the combination process in that one substance breaks down into two or more substances: AB ---> A + B Water‚ or H2O‚ for example

Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

“Suppose you suddenly hear a loud bang… and ask me‚ ‘what made that bang?’ and I reply‚ ‘nothing‚ it just happened.’ You would not accept that.” (Strobel‚ The case for Faith‚ 76) Humans have‚ and always will‚ wonder about the beginning of time. Some creation theories are more widely spread and known than others. A common definition of a ‘theory’ is a proposed explanation whose status is still conjectural‚ in contrast to well-established propositions that are regarded as reporting matters of actual
