My teacher said he'll give an A to the student that comes up with a question that has nothing to do with chemistry. So I decided to go with "Is 1103 a prime number?" I need feedback on whether this is a suitable one or not. I really need an A please help =)

We could be arguing semantics here so I propose two scenarios for you:
1) Your teacher is trying to prove a point that chemistry is involved in everything and no one can come up with a non-chemistry question.
2) Your teacher is willing to give the entire class 'A's just because . . . well, I can't think of a witty reason here, so I'll leave it at that.
As for your question, in scenario #1 the teacher will find some way of showing that 1103 being prime has some chemical connection (it is prime, btw, only divisible by 1 and itself); in scenario #2, you've posed a math question and not a chemistry question so the 'A' is yours.
Maybe try this question:
How were railroads important to the North and South during The American Civil War?
If scenario #1 is in play, he'll find some chemical connection (I don't see one, but I'm a history major); scenario #2, the 'A' is yours.
Good luck!

One way to find out is to divide it by the primes starting from 3 (forget 2, because 1103 is odd, forget 5 because your number doesn't end in 5 or zero) and go as high as the sqrt of 1103 (i.e. the next prime above 33.211, or 37). You don't have to go any further, because your quotient would be less than 33, and you would have already tested those primes.
1103/3 = no
1103/7 = no
1103/11 = no
1103/13 = no
" 17 = no
19 = no
23 = no
29 = no
31 = no
37 = no
Yep. It's prime.

If you cannot divide the number 1103 by any number from 2 to half its root , that is to say from 2 to 33 , you can say it is prime. 1103 isnt divisible by 2,3,4,5 ... 33 so it is prime

Yes it is a prime number. To find out if a number is a prime, find the square root that number (i.e. SQRT of 1103 is approx. 33.2114). Once the square root is found, divide the number in question by all whole numbers LESS THAN the square root (i.e. 2,3,...33). If none of the quotients is whole, voila! your number is prime!

well try to work harded and c what you can do. but if you don't how to work it out just ask a friend to help you. or simply ask another teacher ti tell you if the number 1103 is a prime number or it's your phone number.

It has nothing to do with chemistry
It is a prime number since ti can not be divided by a number higher than 1

Prime numbers are number that can only be divisible by 1 and itself

well the best question you can come up with is "to whom do you think the teacher is going to give an A???" it has got nothing do with any subject

It is a prime number.
How about this one?

Yes, because it can only be divided by itself and 1.
