For the reaction at 298 k, 2no2(g) n2o4(g) the values of δh° and δs° are -58.03 kj and -176.6 j/k, respectively. calculate the value of δg° at 298 k. δg° = kj assuming that δh° and δs° do not depend on temperature, at what temperature is δg° = 0? t = k

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?
