Marcus Hurst urges everyone to “maintain an open mind to the truth.” However‚ he sees a problem with people who‚ due to their pride and self-confidence‚ consider their own opinion to be of higher value than the truth. In his book The Box Top to Life’s Puzzle: Explanations for the Mystery of Life (Toplink Publishing‚ 2017)‚ Hurst explains how pride has led certain people to invent lies and embrace falsehood. For Hurst‚ to embrace the truth is to stand “on the ground of humility.” There are many explanations

The Puzzle of Emergence The puzzle of emergence is a very controversial and complex‚ scientific puzzle. This concept of emergence has been a baffling topic that has stumped many scientists and philosophers throughout the past centuries. George Henry Lewis was the first theorist to give wisdom to this puzzle in the late 1800s and so have many other theorists after this puzzle was first proposed. The term emergence can be defined differently in both a scientific or philosophical situation. It comes

Week 10: Oxidation and Reduction Reactions: The Reactions of Copper Data: Part I: Preparing a solution of copper (II) nitrate Initial mass of copper wire: .520g Mass of copper wire after vigorously scouring: .518g Observations of Copper (II) ribbon mixed with HNO3: Solution turned green. Thick brown gas formed. Copper (II) bubbled vigorously. Cu (II) dissolved‚ solution appeared green/blue. After the addition of H2O a blue crusty precipitate formed. Part II: Synthesis of solid copper

(FAs) can ultimately be degraded through different pathways which include alpha‚ beta‚ and omega-oxidation. Alpha-oxidation occurs at carbon 2 of the chain‚ b-oxidation at C3‚ and omega-oxidation at methyl end of the fatty acid. The location of each mechanism also differs as alpha- oxidation occurs in peroxisomes only‚ beta-oxidation can take place in both peroxisomes and mitochondria. Omega-oxidation occurs in the endoplasmic reticulum of the various tissues. The importance of the differentiation

review of the Equity Premium Puzzle Introduction First time this phenomenon was presented by the economists Rajnish Mehra and Edward Prescott in 1985. They discovered that the return from US equity investments in comparison to the return from a risk free government securities had been much far above during the twentieth century to be interpreted by the traditional economic theories (Siegel and Thaler‚ 1997). Also‚ significant research on equity premium puzzle was made by the Siegel. Siegel

8.07 Work File: Oxidation Reduction Reactions 1. What is the difference between an oxidizing agent and a reducing agent? The oxidation number (overall charge of the atom) is reduced in reduction and this is accomplished by adding electrons. The electrons‚ being negative‚ reduce the overall oxidation number of the atom receiving the electrons. Oxidation is the reverse process: the oxidation number of an atom is increased during oxidation. This is done by removing electrons. The electrons‚ being

moles/1000 mL = .0005 moles/10 mL = moles of hydroxylammonium chloride Ratio of Fe+2 to NH3OH+ = 2:1 2e- + 2Fe+3 --> 2Fe+2 so transfer of 2 electrons NH3OH+ --> something + 2e- Oxidation number of N in NH3OH+ is -1‚ therefore the oxidation number for N on the product side must be +1 because it gains 2 electrons. N2O has an oxidation number of +1 for N‚ so that would work. Data:Equation 1: NH3OH+ + 2Fe+3 --> something + 2Fe+2 Equation 2: 8H+ + 5Fe+2 + MnO4- --> 5Fe+3 + Mn+2 + 4H2O Equation 3: 6H+ +
