How many moles of ammonia will be formed upon the complete reaction of 0. 288 moles nitrogen gas with excess hydrogen gas? nitrogen (g) hydrogen (g) ammonia (g).

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
