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?

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

the dependant variable is spilled water

the independent is the heat

the volume increases

there is none because earth is stationary and flat.
