Okay, so here we want to know the present yield of the reaction based on the spheres we have.
00:05
So if we look at the spheres, we have white ones, and then we also have red ones.
00:11
I'm assuming that these red ones are supposed to be blue as stated in the picture.
00:16
So these are representing h2, and these are representing n2.
00:20
And then on the other side we have three white ones surrounding a red one, which is nh3.
00:29
And then we have some leftover nh2 and h3.
00:31
Or sorry, nh2 and h2.
00:33
So if we count how many white spheres we have on the left side, there should be 12.
00:45
And if we count how many we have nitrogen we have on the right side, we also have 4n2.
00:52
And if we write the balanced equation to turn hydrogen and nitrogen into ammonia, we can go ahead and do some reactions to do geometry to see what the percent yield should be, or what the theoretical yield should be, and then we can calculate the percent yield.
01:08
So to balance this, we need two nitrogen on both sides, so we can put a two in front of the ammonia...
