Gabrielle Rae V. Bueser HFH23 June 15‚ 2013 Reaction Paper: Spoliarium As we enter the hall of the National Museum of the Philippines‚ the prominence of "Spoliarium" an oil on poplar completed in 1884 by National Artist‚ Juan Luna‚ is remarkable. The super- sized painting depicts a dark hollow beneath the Roman arena referred to as the Spoliarium where the bodies of slain gladiators are being dragged away for disposal. This is the time in history when the Romans travelled to Europe and collected

of an object is determined using a process called titration. According to Petrucci et al.‚ titration is a reaction carried out by the carefully controlled addition of one solution to another. It has several types like acid-base titrations and redox titrations. This experiment focuses on the latter type‚ the redox titration. A redox titration is based on an oxidation-reduction reaction between analyte and titrant (Harris‚2009). It involves the transfer of electrons between the two solutions. This

The Displacement Reactions Purpose: to see how displacement reaction works with different chemicals and what chemical has more reactivity series then other Hypothesis: Iron + Copper Sulfate: Iron will displace copper because it is more reactive and it is going to end up as Iron Sulphide + Copper Copper + Silver Nitrate: Copper will displace Silver because it is more reactive and it is going to end up as Copper Nitride + Magnesium + Copper oxide: Magnesium will displace Copper because it

Reaction to James Joyce’s “Araby” James Joyce’s “Araby” is no different than his other works. The story of “Araby” is layered and profoundly complex yet‚ so are his other works. “Araby” is the story of a young boy who lives in Dublin and is completely captivated by a female counterpart. Something that is quite evident all throughout the story is that this boy‚ although captivated by this girl‚ does not once make mention of her name. It seems as if to speak her name would taint his idea of

Reaction to Dr. David Callahan I was prepared to be interested in hearing this person speak‚ but when he started to list some “facts”‚ I started to tune out. The one that stood out for me was that‚ “billions of dollars have been lost for the music industry because of illegal downloading.” If people who downloaded the illegal music actually purchased it‚ yes- that would be more money in the big wigs pockets. However‚ many studies have shown (and I read another one on Techcruch right before seeing

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

The movie itself started out slow‚ I have noticed that with a lot of older movies like this one‚ it took a while for me to catch on to the point of the movie‚ or to figure out what it was about. Slowly the movie started picking up and it began to make more sense to me. There are a lot of characters that I had to write down on a piece of paper because
