This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

Environmental Science The Scientific Method Amber Steadham October 31‚ 2012 Abstract: We conducted several experiments using the Scientific Method. We made observations‚ recorded them and used our observations to propose a hypothesis. The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical

The Growth of Bacteria Influenced by Different Antibiotics Introduction: Plants are made up of three basic kinds of tissue that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter

Today I’m going to be speaking to you about the street gang known as the Bloods. I will be discussing the origin of the gang‚ some of the gang’s important members and the impact the gang has on the present day. It all began in 1971 when the gang that eventually came to establish the Bloods was created. The name of this gang was the Piru Street Boys and they were actually a set of the Crip gang‚ today’s biggest rivals of the Bloods. When the Piru Street Boys began their operations they were working
