Document Summary
Carbon 13, 14,15 are all different isotopes of carbon 12. The most stable ones are the ones that impact molecular weight. Ph, what does ph 10 mean vs. ph 2. Electromag radiation, higher energy bands vs. lower energy. Lewis structures: oxygen, sulphur, water, ammonia, why is water bent, surface tension and interesting properties of it. If you put a cup of water in a microwave the water will heat up because the water needs to absorb it, there needs to be something to absorb the energy (vibrations cause it to heat up) Co2, methane and coc absorb infrared but not enough to break bonds, so these molecules heat up, gas molecules bump into other gas molecules eventually leads to a hotter atmosphere. Bond energies + combustion: balance equations, combustion equations. Ch4 + 2 o2 co2 + 2 h2o (need to know how to balance) and then calculate the total bond energy (given the numbers)
