Post Lab Questions: 1. What did you notice about the distance between the atoms as the number of bonds increased? (Compare bond of H2S and H20) 2. What is the relationship between atomic size and bond length for H2O/HS and CO2/ CS2? 3. What are the carbon-carbon bond lengths in each of these three molecules? Using Table 7.2 draw the structures for C2H, CH4 and C2H2, and determine the carbon-carbon bond lengths for each structure. 4. What is the pattern in bond length that you notice for the carbon compounds in question 3?

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different.  let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones).  now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first.  for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours.  so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia.
