Four different gases are pumped into a container. The total pressure inside the container is 740 torr. The partial pressure of gas X is 340 torr. The partial pressure of gas Y is 264 torr. The partial pressure of gas Z is 100 torr. What is the partial pressure of the fourth gas?

D.na is the answer hope this

Ok so co(g) is not pronoused that. the only clue is that youpronouse it the oppisote way. 

The internal energy of the system we can term it as total potential energy and kinetic energy. energy flows out of the surrounding from the system then we can say that the internal energy of the final state is lower than its initials. the sign of  δesystem is negative.δesystem = efinal - einitial=-ve  efinal  ∠einitial.

No, because shearing causes strike-slip faults and normal faults are caused by tension.
