Assuming all volume measurements are made at the same temperature and pressure, how many liters of oxygen gas would it take to react completely with 7.25 liters of hydrogen gas? show all of the work used to solve this problem.. unbalanced equation: h2 (g) + o2 (g) -> h2 o(g)

Plz mark brainliest 30 points 1) find the momentum of a 12 kg snowball that is rolling with a velocity of 9 m/s. 2) an 8 ball with a mass of .5 kg is sitting at rest. it is hit by the cue ball (1 kg) traveling at 2.5 m/s. if the cue ball is at rest after the collision, how fast is the 8 ball traveling after the collision? 3) two football players are running toward each other. if the offensive player is 75 kg and is running 8 m/s, how fast must the 60 kg defensive player run in order for the two players to hit and stop?
