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

BIOPOL Biopol is a biopolymer that is an environmentally friendly biodegradable plastic made from renewable resources (made naturally in plants from starch and glucose). Biopol is the brand name for a group of biopolymers often called PHAs or PHBs. The continual use of petroleum to make polymers for plastic will eventually run out and hence Biopol was introduced as a polymer replacement for petroleum. It is made from an organic substance known as Alcaligenes eutrophus which is a microorganism.

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds

Then you drop the Alka-Seltzer in the water and time how long it takes it to dissolve in the water. 3. Then we need to make the temperature go up then we need to drop the Alka-Seltzer in the water again and see how long it takes it to dissolve with the new temperature. 4. Now

Chocolate is made from the cacao bean. According to Rodney Lipson‚ “Cacao has been a cultivated crop for at least three thousand years‚ probably quite a bit more. The people who first utilized Cacao were the inhabitants of what is now Venezuela” (Lipson) This group of people would eventually spread the cacao bean in northwestern South America. Cacao was clearly highly valued by these people and they spread it northward through trade with their neighbors. It was probably the Maya‚ over 1500 years
