1. Write a balanced equation for the formation of carbon monoxide (CO) from the elements of carbon, C, and oxygen, O2.
2. Calculate the percentage of sulfur, by weight, in sulfur trioxide, SO3.
3. A gas is contained in a balloon with a volume of 35 L at a temperature of 30 degrees C. What temperature must be reached in order for the balloon to expand to a volume of 50 L, at constant pressure?
Please show work. Any and all help is very much appreciated!! Thanks in advance! :)

1. 2C + O2 ===> 2CO
2. Atomic weights: S=32 O=16 SO3=80
32/80 x 100% = 40%
48/80 x 100% = 60% (48 is the weight of three O's.)
3. V1/T1 = V2/T2
T2 = V2T1/V1
T1 = 30C = 303K
T2 = (50L)(303K)/(35L) = 433K
433K - 273K = 160C
