Steven Leung 9/19/06 Lab Report The Empirical Formula of a Copper Oxide Purpose: To convert an unknown copper oxide to copper (Cu) metal using natural gas to provide a reducing environment as shown below: Cu O (s) + CH (g) ¨ Cu (s) + Co (g) + H O (g) From the mass difference between the unknown copper oxide and the Cu metal generated at the completion of the reaction and the molar mass of Cu and oxygen‚ the empirical formula of the original copper oxide can be calculated.

structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148.09 09 g mol -1. From this knowledge the unknown molecule must include

Have you ever sat and wonder if college is anything like the real world? During school‚ we are basically giving detailed direction‚ while we enter the real world our only goal is to succeed. For students who are more independent‚ this could be an enormous relief. For those who are still getting their footing in the real world‚ this may be a challenge. Although there are many similarities at which you can apply into your career. Those similarities include Engagement in classroom discussions‚ completion

Cost‚ Volume‚ and Profit Formulas All businesses require becoming profitable or at some point they will fail. Accounting plays an essential role in determining if the company will become successful and continue to do so over time. Using well-defined formulas in order to assess the exact numbers will facilitate the actions a company needs to carry out in order to maintain its goals. The accounting department would look at the cost-volume-profit analysis to concentrate on the different components

‘ Not a Click Away: Joseph Kony in the Real World ‘ written by Dinaw Mengestu exposes the reality that lies in front of us. Kony 2012 was vital in raising awareness amongst millions of people and igniting a self-responsibility to take action against Joseph Kony. “if we’re not here… it’s like it never happened” ( reporter 2006 )‚ this is crucial in realising that Kony 2012 needed to take place as Joseph Kony had almost been forgotten in some places and not even known in others.

Primoratz writes that “…radical feminists typically question the very relevance of consent to the morality of sexual acts.” Rape is to be quite frank‚ the lowest and most demeaning act a man can do to a woman. Most would say that rape is physically forcing a woman to engage in a sexual act against her will. Radical feminists take a hard stance against this and believe most “normal” sex is to be included when discussing rape. Feminists argue that the very social fiber of our society in which

‘Radical feminist theology is inspirational but wrong’ Some would argue that radical feminism was inspirational and it was not wrong as it was necessary in order to achieve equality for women. Harriet Taylor forcefully set out the arguments in Enfranchisement of Women for the right to vote and also for ‘equality in all rights‚ political‚ civil and social‚ with the male citizens of the community’. She argued that true partnership between men and women would also mean equal pay and financial independence
