`one way to make ammonia is to synthesize it directly from elemental nitrogen and hydrogen (though this isn't that easy). the equation for this reaction would be n2 + 3 h2 → 2 nh3. if you are able to stream in 7.0 g of n2, what would be the minimum amount of h2 in grams that would be required to completely react with this amount of n2?

a. 1.5 g
b. 0.5 g
c. 0.75 g
d. 3.0 g
e. none of the above

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?

Two nails have identical sizes and shapes. in one nail, 20 percent of the domains are lined up. in the other nail, 80 percent of the domains are lined up. which has stronger magnetic force? first answer gets brainliest!
