Thoreau on Civil Disobediance essays

Thoreau on Civil Disobediance essays Henry David Thoreaus basis for objecting to the government was very well thought-out, as he details three main tenets in opposing an unjust government. He starts out by stating the individual duties each person has as a mere citizen, as a good neighbor. Things such as maintaining your humanity and conscience are key, he says. Then, he outlines what people should do in response to government injustices, mainly in the form of civil disobedience and not partaking in unjust government practices. Finally, Thoreau speaks about his own experiences with civil disobedience and what he has seen of it. Speaking about his time in jail, he talks about how he has tried to follow his own moral code instead. Overall, he stresses much importance on the individual and individual action, and the effect of immediate action from the minority. Therefore, Thoreaus main point in Civil Disobedience is for the individual to immediately do what he thinks is right in a moral sense, even if it involves opposing the government. The first part of his essay details what duties people have as good neighbors, not just as mere objects of the government. People should not resign their consciences over to the government he says, as others cannot be trusted with ones conscience. The majority conscience should not always be followed either, as it only expresses the desires of the strongest group, not the most virtuous or morally correct. And since that is what the government does, Thoreau is opposed to it. However, instead of demanding no government whatsoever, he wants a better one immediately.

Instead of following only the law and nothing else, which is what the government makes some people do, it robs people of their humanity and turns them into mere machines. One example of this type of person is the soldier, who uses no moral influence in...

Chemical Change Examples in Chemistry

Chemical Change Examples in Chemistry Chemical changes involve chemical reactions and the creation of new products. Typically, a chemical change is irreversible. In contrast, physical changes do not form new products and are reversible. Some Common Chemical Changes The rusting of ironCombustion (burning) of woodThe metabolism of food in the bodyMixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH)Cooking an eggDigesting sugar with the amylase in salivaMixing baking soda and vinegar to produce carbon dioxide gasBaking a cakeElectroplating a metalUsing a chemical batteryThe explosion of fireworksRotting bananasGrilling a hamburgerMilk going sour Less-familiar chemical reactions are also examples of chemical changes. While its not always easy to tell a chemical change has occurred (as opposed to a physical change), there are some telltale signs. Chemical changes may cause a substance to change color, change temperature, produce bubbles, or (in liquids) produce a precipitate. Chemical changes can also be considered to be any phenomenon that allows a scientist to measure  chemical properties.
