During the American revolution‚ Patrick Henry’s cry‚ “Give me liberty or give me death‚” was a philosophy adopted by many as they aimed to separate themselves from the British‚ but this statement is problematic due to the fact that it suggests liberty is something opposing‚ or simply different‚ from death. As a country we continue to value this cry for liberty as a fundamental value‚ but this same liberty was not given to women after the revolution‚ or centuries to come. As a result‚ there were many

When a really large unstable isotope changes into to smaller isotopes that are 2 completely different elements. the nucleus has to be larger than 230(mass). They are really slow and spontaneous. Fission = splitting. Can create a chain reaction. (picture above). Critical mass= must be enough mass in a reaction or enough fission type mass‚ fissionable mass‚ for the reaction to continue to go on.(minimum amount). Sub critical mass= mass of fission material that doesn’t have enough to keep the reaction

Article Excerpt Access to the world’s oil supplies is a principal factor behind US government policy‚ as the events of the past two years have unmistakably shown. And no wonder: possessing only 2% of the world’s reserves of oil‚ the US consumes 25% of global oil production at a cost of $150bn per year. Of this‚ 70% is in the form of gasoline (petroleum) or diesel fuel for transport use. Given the finite supply of oil‚ this cannot go on. Certainly‚ by 2050‚ competition for oil supplies will be

5.) a.) b.) Ethyne (C₂H₂) has the shortest C-to-C bond because there is a triple bond between the two C’s. The shorter the bond‚ the smaller the distance between the two bonded atoms‚ a single bond has the largest distance between two bonded atoms. c.) i.) trigonal planar ii.) pyramidal d.) This is not true because the bonds described are intramolecular forces‚ C-H‚ C-O‚ O-H‚ which are not affected by boiling. When boiling occurs‚ added energy overpowers intermolecular forces‚ not

Trends in the Periodic table March 24‚ 2013 Four trends that will be covered: Atomic size Ionization Energy Electronegativity Electron Affinity Each of these has a group trend and a period trend A group trend refers to what is happening with the atom as you travel up or down a column of the periodic table. A period trend refers to what is happening with the atom as you move left or right across a row of the periodic table Atomic Size When discussing an atom’s size‚ usually the
