The drinking age law is a law that is greatly debated. There are many pros and con to the drinking age being lowered. At the age of 18 you are considered an adult in the eyes of the public. Many think a young adult is not mature enough to have a sip of beer but somehow is old enough to fight for our country. The drinking age should be lowered because an individual is considered an adult at the age of 18‚ laws about drinking can be more harmful the good‚ and if you are able to all these adult things

Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n

Literary devices are a common technique in writing to enhance the writer’s style. These devices enrich the content of the writings by offering another perspective on them and can also be used to create a tone or ambience. In “Straw Into Gold: The Metamorphosis of the Everyday‚” Sandra Cisneros uses literary devices such as metaphors‚ conceits‚ and details to reveal the reflective atmosphere of her writing in order to convey her experiences as a writer. In her story‚ Cisneros applied metaphors to

vice president of a beer company in a state that sets the legal drinking age at 21. Your boss asks you to organize a lobbying effort to have the drinking age reduced to 18. What would you do? A. I would do research and report my findings to my boss. Although it might seem like a good idea to do so -higher sales‚ and therefore higher revenue and profit- lowering the drinking age would be a losing battle. States can lower the drinking age back down to 18 or 19 but the amount of federal highway funds
