Stratford-upon-Avon. Analyzing this short story written by Arthur C. Clarke‚ one can conclude that he must enjoy writing about scientific breakthroughs and he utilizes vocabulary that is very different from most authors. The entire story is about a hydrogen bomb destroying the city of Stratford-upon-Avon. The story is told a few days after the incident. The story describes the state of the small town after the bomb was dropped on it. The bomb is destructive‚ there are no humans‚ animals or even dialogues

Hydrogen Fuel As An Alternative Energy Source To Replace Fossil Fuels Since the beginning of industry humans have been in search of fuel to power machines and generate energy. Fossil fuels‚ such as crude oil and coal‚ discovered beneath the Earth’s surface were found to be an excellent source of fuel. These fossil fuels are burnt in order to generate the energy required to complete various tasks. Many nations count on coal‚ oil and natural gas to supply most of their energy needs‚ but reliance

Purpose Since there are two possible oxidation numbers for the iron nails‚ by this experiment we will need to determine the actual oxidation number of the iron in this experiment. Hypothesis As said in the introduction there will be two possible decomposition reactions: Fe (Ⅱ) + CuCl2 (aq) → Cu + FeCl2 2Fe (Ш) + 3CuCl2 (aq) → 3Cu + 2FeCl2 We can measure the mass of the two iron nails‚ and the copper after the reaction. Thus‚ we can compare the ratio of the mole and the mass of iron and copper. Procedure

Decomposition of Sodium Chlorate to Create Oxygen Gas Introduction: There are several types of chemical reactions. Those reactions include synthesis‚ decomposition‚ single replacement‚ and double replacement. In this experiment‚ we will be decomposing sodium chlorate to create oxygen gas. In a decomposition reaction‚ a chemical compound is being separated into elements or simpler compounds. AB → A + B is a simple way of expressing what happens in a decomposition reaction‚ AB break down into A
