Need help as soon as possible please and thank you :) Given the reaction at equilibrium:

2SO2 (g) + O2 (g) <=> 2SO3 (g) + 44 Kcal

Which change will increase the concentration of SO3 (g) ?

Select one:
a. increasing the volume of the reaction vessel
b. decreasing the pressure
c. increasing the temperature
d. increasing the concentration of O2 (g)
e. decreasing the concentration of SO2 (g)

8) a mixture of he, ne and ar has a pressure of 7.85 atm. if the ne has a mole fraction of 0.47 and 8) ar has a mole fraction of 0.23, what is the pressure of he? a) 4.2 atm b) 3.7 atm c) 5.5 atm d) 2.4 atm e) 1.8 atm

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave

Select the correct answer. wax is a nonpolar substance. in which type of substance is it most soluble?
