1.) a gas has a volume of 300 ml at 25 atm. What is the volume 2.) if the aerosol can is still 100 KPa and 15*C and you chance the temperature to 1000*c what formula will you use? 3.) if the aerosol can is still 100 KPa and 15*C and you chance the temperature to 1000*c what is the new pressure ? 4.) a balloon contains 30.0 L of a gas at 103 KPa. What is the volume of the gas when the balloon rises to an altitude where the pressure is only 25.0 KPa

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.
