I NEED ALL 4 PROBLEMS DONE OUT STEP BY STEP WITH THE AWANSER = I NEED TO CHECK ALL MY STEPS (NOTE: PLEASE DO NOT DO IF YOU DO NOT DO ALL STEPS AND ANSWER) THANK YOU

SHOW ALL WORK WITH A FINAL ANSWER


1.  A nitogen container that has 100.0 liters of gas at a pressure of 3200 psi ruptures in a room at 28° C and 0.92 atm pressure.  What volume will the nitrogen gas occupy in the room after the bottle empties?  









2 A typical vacuum system can obtain a pressure of 1.0 x 10-8 (-8 power)  torr.  Calculate the number of gas molecules present in 1.0 liter of gas at this pressure and 25° C.  








3What is the partial pressure of each gas and the total pressure in the container of a gas mixture containing 10.0g of Xe, 10.0g of SF6 (small 6), and 10.0g of He in a 3.00 liter container at 27° C.  








5.  The term "limelite" comes from the stage lights that were used in the 19th century.  These lights burned acetylene (C H ) which was made by reacting calcium carbide made from lime with water according to the following reaction:

CaC2  (s)   +   2   H2O (1)  ---->   C2 H2  (g)    +    Ca (OH) 2 (s)


How many grams of Ca C2  would you need in a lamp if the lamp consumed 100.0 ml of gas per minute, the show was 1.00 hour long, the temperature of the room was 32° C and the pressure was 760.0 mm of Hg?
