Example #1: Calculate the enthalpy for this reaction:
2C(s) + H2(g) -> C2H2(g) H = ? kJ
Given the following thermochemical equations:
C2H2(g) + (5/2)O2(g) -> 2CO2(g) + H2O() H = -1299.5 kJ
C(s) + O2(g) -> CO2(g)
H = -393.5 kJ
H2(g) + (1/2)O2(g) -> H2O()
Example #1: Suppose we had 1.00 mole of sucrose and proceeded to mix it into
some water. It would dissolve and make sugar water. We keep adding water,
dissolving and stirring until all the solid was gone. We then made sure that when
everything was well-mi
Problem #1: Determine the volume of occupied by 2.34 grams of carbon dioxide gas at STP.
1) Rearrange PV = nRT to this:
V = nRT / P
V = [ (2.34 g / 44.0 g mol1) (0.08206 L atm mol1 K1) (273.0 K) ] / 1.00 atm
V = 1.19 L (to three s
Example 1: What is the mole fraction of cinnamic acid in a mixture that is 50.0% weight
urea in cinnamic acid (urea = 60.06 g/mol; cinnamic acid = 148.16 g/mol)
1) Let us assume 100.0 g of this mixture are present. Therefore:
50.0 g is urea
