common energy source. When people go outside and see the sun‚ an alternative energy source is the last idea that comes to mind. The sun is often ignored and so is solar energy‚ but this should change. “The Sun provides 100‚000 terawatts which is about 10‚000 times more than the present rate of the world’s present energy consumption. Photovoltaic cells are being increasingly used to tap into this huge resource and will play a key role in future sustainable energy systems.” (Grätzel 993). The Sun

Today‚ many countries are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs

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

Burning Money Chemistry Demonstration Principle You soak a note in ethanol (alcohol) and it will burn when lighted‚ leaving the note untouched. This is because alcohol is more flammable‚ and burning alcohol causes it to vaporize‚ along with the water present in the solution. This removes heat from the note and prevents it from reaching its combustion point.
