A sample of oxygen has a volume of 7.84 mL at a pressure of 71.8 mmHg and a temperature of 25.0°C. What will be the volume of the gas if the pressure is changed to 101
mm Hg and the temperature is changed to 0.00°C with all other variables remaining constant?
The

Much of the general structure and physical properties of the interior of the earth are inferred from: a)deep oil and gas bore holes b)geologic investigations c)analysis of seismic waves d) study of volcanoes

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.

Choose one literary selection from this semester in which you think the setting has a great impact on the work. in a full paragraph name the work, describe the setting, and explain why it is so important to the overall story or poem.
