5. ANALYZING RESULTS A student has the fol-lowing data: V1= 822 mL, T1= 75°C, and T2=−25°C. He calculates V2 and gets −274 mL. Is this value correct? Explain why or why not.

In which phase(s) do the molecules take the shape of the container?

Draw the lewis dot structure for each of the following polyatomic ions

Suppose a pair of chemical compounds a and b can react in two different ways: a + b -> c reaction 1 gives product c. a + b -> d reaction 2 gives product d. the following facts are known about the two reactions: . reaction 1 is endothermic and reaction 2 is exothermic. if a reaction vessel is charged (filled) with a and b , then at first d is produced faster than c. use these facts to sketch a qualitative reaction energy diagram for both reactions. note: because these sketches are only qualitative, the energies don? t have to be exact. they only have to have the right relationship to each other. for example, if one energy is less than another, that fact should be clear in your sketch.
