2:7 ratio of ethane to O2 = 15:x 9solve for x)
x=52.5 mol O2
The pressure will continue to build up eventually causing a release of pressure or an explosion.
Answer:

Explanation:
Hello!
In this case, since the mole fraction of both gases in the tank is computed via:

It means we need to compute the moles of each gas, just as it is shown down below:

Thus, the mole fractions turn out:

Best regards!
This type of energy travels through vibrations on waves = 7. sound energy
This is the energy found in the nucleus of an atom = 9. nuclear energy
This type of energy can be transferred in three different ways = 6. thermal energy
This is the term used when energy changes from one form to another = 10. energy conversions
This has to do with the speed of an object and how much mass it has = 2. kinetic energy
This can be either kinetic or potential and has to do with the energy of position and motion of an object = 1. mechanical energy
This type of energy is stored energy = 3. potential energy
This is radiant energy from the sun = 5. light energy
This is energy that is transferred by the movement of electrons through a conductor = 4. electrical energy
This type of energy is often found in things like batteries or food = 8. chemical energy
hope this helps
