Sarah Aguilera June 30‚ 2013 Lab # 4 Properties of Gases Purpose The purpose of this lab was to investigate and discover the physical and chemical properties of some gases. Throughout this lab the ability to identify if and when gasses were present was enhanced. Data Observations During the first step of this lab‚ when obtaining the hydrogen from the mossy zinc and the hydrochloric acid‚ it took a lot longer than I thought it would for the water in the pipet to be displaced. I was tempted

increase costs‚ such as requiring the development and integration of new systems or procedures or establishing a minimum wage that small retailers may not be able to afford. The retail industry also relies heavily on government-supported road‚ rail and water transport infrastructure to move goods and bring customers to retail locations. The Role of Economic Factors: Retail sales are driven by the economic environment. A robust economy correlates to an increase in consumers’ disposable income

The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them. Procedure Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper

Title : Properties of hydrocarbon Objective : 1) To study the properties of hydrocarbons. 2) To determine the unknown samples. Results : Part A : Combustion Compounds Observations Hexane There was orange flame and burned mildly during the burning process. No soots and smoke were produced. C6H14 + 19/2 O2 6CO2 + 7H2O Cyclohexene Orange flame burned vigorously. A small amount of black soot and smoke were produced during the burning process.

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

originates. This region is typically at the elevation where freezing occurs within the cloud. Freezing‚ combined with collisions between ice and water‚ appears to be a critical part of the initial charge development and separation process. During wind-driven collisions‚ ice crystals tend to develop a positive charge‚ while a heavier‚ slushy mixture of ice and water (called graupel) develops a negative charge. Updrafts within a storm cloud separate the lighter ice crystals from the heavier graupel‚ causing

Property taxes – local taxes‚ immovable property/land tax‚ motor vehicle tax . (Lukas Szita) A property tax also known as millage tax is a charge on possessions that the holder is obligatory to pay. The tax is imposed by the governing authority of the area in which the property is placed; it can be a national government of country‚ a federated state‚ a county/region‚ or a municipality (In Slovak Republic property tax is the most important income for municipalities). We basically distinguish four

2006; Cushnie et al.‚ 2005). As a consequence‚ natural antimicrobials are receiving a good deal of attention for a number of micro-organism-control issues. Reducing the need for antibiotics‚ controlling microbial contamination in food‚ improving shelf-life extension technologies to eliminate undesirable pathogens and delay microbial spoilage‚ decreasing the development of antibiotic resistance by pathogenic microorganisms or strengthening immune cells in humans are some of the benefits(Abou-taleb et
