I am currently doing limiting reagent and excess part of it, and i have trouble, with calculating here is the question

N2 + 3H2 ---> 2NH3
How many grams of NH3 can be produced from the reaction of 28g N2 and 25g of H2?

I did 25g divide 2g = 12.5mols then divide by 3= 4.17mols
28g divide by 28g = 1 mol then divde by 1= 1 mol
so 1 mol is limiting and the 4.17 is excess
i use 1 mol times 2NH3 divide by 1 N2 = 2 mols x 17g = 34g of NH3
then the second part asks How much of the excess reagent in problem 1 is left over?
im assuming thats the 4.17mols, and i cannot find how to figure it out, becuase my answers does not match the answer on back of book..so please someone help, thanks

If you had to spend 2 days at the beach in Viet Nam, would you choose Nha Trang on the west coast or the southern island of Phu Quoc? Price isn't an issue. Thanks!

my mom is pregnant again believe it or not and im now 16, i was just wondering about this bc usually my mom is a Pepsi fanatic and shes been craving one for some months now, and she was scared to drink it... but last night she drank one. I asked her why you cant drink carbonated drinks while your pregnant and she just said that it can give you very bad integestion (gas) but she also didnt quite understand because they tell women to drink things like sprite and gingerale to settle their stomachs... i was just wondering is it safe what does it really do?

It's a long storey, so I won't explain it, but I actually saw this happen to another child. My nephew was playing with this child. I thought it was the child's father, but when the child left with a woman, and the man who hit him stayed behind, I realised with horror that this man hit a complete strangers child.

When purchasing a bottle of my regular goldfish food I noticed that ther were quite a few breed specific foods for goldfish. Do these provide any benifits to my goldfish or is it just a scam. (They were more expnsive)

"omg, omg, they have called me a racist because I want our laws enforce"
-This is what anti-illegals say all the time. ok, most, not all.

I think it's not fair that anti-illegals accuse people of calling them racist only because they are against illegal immigration and want the laws enforced.

However, you and I know for a fact that that is not the case. People call anti-illegals racist because they (the ones who do it) have to come down to racism to argue a point on this issue.

No one is calling any anti-illegal a racist for what they stand for. Nevertheless, once they start ranting about Mexicans or Hispanics then the hate arises.

So for you anti-illegals, do you actually believe you are the target of being called a racist for what you stand for?? it's sad if you do, because that's not why people call you racist.
Hope I was clear, but I think I was clear with what I was trying to say. Thanks!

What made you suspicious? What did you do with your suspicions? If you are the type that would prefer to pretend it isn't happening, how long would you let it go? What are certain things that would make you very suspicious? What did you do to try and catch him/her? Anything you have to add. THANKS!
