lab‚ we are now able to calculate the molar heat of combustion for paraffin‚ since we have the difference of the mass in candle before/after and the periodic table of elements (for converting g to moles of paraffin). Molar heat of combustion = (kJ of heat)/(mole of fuel) However‚ we do not know how much heat was released nor the mole of fuel (paraffin). In order to find the amount of heat released‚ we use the formula: g=mcΔT. Here‚ g represents the heat‚ m represents the mass of water‚ ΔT represents

How pride affects the world I do agree that pride is a wonderful terrible thing. In the story‚ The Scarlet Ibis‚ pride is what helped Doodle to do things he never could have done‚ but in a way it also led to his death. Doodle’s brother wanted a normal brother who could do things with him through his pride he had accomplished that. Ultimately though it was through his pride that he ended up having no brother at all. Pride was great for Doodle’s life because he got to experience things he never would

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above

Stress is a very common issue among all individuals. It has been discovered that all people‚ regardless of age and social status‚ experience some degree of stress. When the body is introduced to more than it feels as if it can handle appropriately‚ it has a natural tendency to react to the things that it interprets as a direct threat. We each have a response that is actually instinctual and ultimately for self protection. Many medical professionals refer to this as the "fight or flight response"

proper nutrients‚ it is difficult for a plant to continue to live. Therefore‚ photosynthesis is necessary for a plant’s vitality. The goal of this experiment is to observe and identify the impact that light has on a plant. Hypothesis: If light affects photosynthesis in plants‚ then the plants growing under the high light environment is expected to grow more than the plants in the medium and no light environments. Materials and Methods: In this lab‚ the plants that were tested were the Mother

7/16/12 Heat of Fusion Heat of Fusion for Ice Introduction: This lab report is a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water. To calculate heat of fusion‚ one must understand heat of fusion. Heat of fusion is the amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound‚

relationship should be to connect with one another. However‚ how can one connect with another when distracted by one’s cellular device? Cell phones play a huge role in relationships because even a quick glance can make the other feel not so important. It’s almost saying “You aren’t as important as what is going on in my iPhone right now.” Technology in general can ruin any relationship but our main focus here is how cell phones affect couples. When one love bird leaves‚ the other starts to feel
