3) A rigid 11.7 L sealed vessel containing 3.3 mol of O2(e), 1.6 mol of CH4(g), and 2.3
mol of He has an internal temperature of 78°C.
a. Calculate the partial pressure of each gas.
b. W hat is the total pressure in the vessel?
c. Find the mole fraction of each gas in the vessel.
d. A lab technician ignites the mixture in the flask and the following reaction
occurs: CH4(g) +2 02(g)→ CO2(g) + 2 H2O(g). Find the mole fraction of
each gas in the mixture after the reaction.
(Hint: Use an ICE chart. There is a limiting reactant.)

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
