Freon-12 (CF2Cl2) which has been widely used as a refrigerant and aerosol propellant, is a dangerous air pollutant , In the troposphere, it traps heat 25 times as effectively as CO2, and in the stratosphere, it participates in the breakdown of ozone. Freon-12 is prepared industrially by reaction of gaseous carbon tetrachloride with hydrogen fluoride. Hydrogen Chloride gas also forms. How many grams of Carbon tetrachloride are required for the production of 16.0dm^3 of Freon-12 at 27C and 1.20 atm

1) A baker uses sodium hydrogen carbonate (baking soda) as the leavening agent in a banana-nut quickbread. The baking soda decomposes according to two possible reactions.
Reaction 1: 2NaHCO3(s) go to Na2CO3 (s) +H2O+ CO2(g)
Reaction 2: NaHCO3(s)+ H(aq) go to H20 (l)+CO2(g)+ Na(aq)
Calculate the volume in mL of CO2 that forms at 200C and 0,975 atm per gram of NaHCO3 by each of the reaction processes.
2.)A weather balloon containing 600 L of He is released near the equator at 1.01atm and 305 K. It rises to a point where condition are 0.489atm and 218K and eventually land in the northern hemisphere under condition of 1.01 atm and 250 K. If one fourth Helium leaked during the journey What is the volume (in L) of balloon at landing?

1)Will the volume of a gas increase, decrease, or remain the same unchanged for each of the following sets of change.
a) the pressure is decreased from 2 atm to 1 atm, while the temperature is decreased from 200C to 100C
b) the pressure is increased from 1 atm to 3 atm, whle the temperature is increased from 100C to 300C
C) the pressure is increased from 3 atm to 6 atm, while the temperature is increased from -73C to 127 C
d) the pressure is increased from 0.2 atm to 0.4 atm while the temperature is decreased from 300 C to 150 C

2) Analysis of newly discovered gaseous silicon-fluorine compound shows that it contains 33.01 mass% Silicon at 27 C , 2.60 grams of compound exerts a pressure of 1.5atm in a 0.250 L vessel what is the molecular formula of the compound
