As Ernest Hemingway said: “There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self.” And that’s‚ to my mind‚ the way every person should follow. I am Yang Qi.It is how I try to live‚ always improving and getting better. Therefore‚ to be pretty honest with myself‚ I decide to do the thing I think I cannot do; I’ve concluded that good and integral qualities of my nature are positive attitude‚ thoughtfulness for other people‚ and cheerfulness

The Miner’s Wives by Ben Shahn takes a bitter look at one of the lifestyles of the early 20th century - that of the down-trodden coal miner. In the foreground of the picture‚ we see the miner’s wife referenced in the title. She carries a bleak expression‚ her back turned to an older woman and a child‚ presumably her mother and her offspring. Two men walk away into the distance‚ and one set of clothing hangs above‚ unclaimed by its owner. The woman has just been informed of the mining accident which

After watching “The Devil’s Miner” and do some additional research I have picked two issues that come along with poverty in Latin America. The first issue that I believe is important is that many individuals go to bed hungry and children are not being fed properly. Although the number of malnurshinoshed individuals has decreased by a lot in the past couple of decades‚ there is still a huge number of people that are not getting the appropriate nutrients.

3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water when heated

Rocks containing copper compounds (such as copper carbonate) are called ‘copper ore’. Copper is extracted from copper ore by a series of chemical‚ physical‚ and electrochemical processes. Ores can be classed as ‘high grade’ or ‘low grade’ depending on the percentage of copper compounds (e.g. copper carbonate) they contain. After mining‚ the ore is crushed‚ roasted‚ smelted and then electrolysed to extract the copper. Suggested Equipment Boiling tube Samples of different carbonate ores‚ containing

In 1947‚ One hundred eleven men were killed in an explosion that took place at the Centralia No 5 mines located in the state of Illinois. The explosion was caused by highly explosive coal dust that was ignited by an explosive charge.

A Sequence of Chemical Reactions: Transforming Copper Briefly describe. a) Why must you carry out the oxidation of Cu with HNO3 in a fume hood? Concentrated nitric acid is a toxic oxidant. Avoiding skin contact or inhalation is highly important. The reaction between Cu and HNO3 produces NO2‚ a toxic brown gas; therefore working under the fume is necessary in order to prevent inhaling the toxic gas. b) Why you should be particularly careful when you work with 3 M H2SO4 solution?
