in the reaction 3H2+N2--> NH3,what coefficient should be placed in front of NH3 to balance the reaction?
2 answers:
The best way to solve this is to list all the elements out and count them.
Count subscripts first (if there is no subscript then there is 1 atom)
Then multiply by the coefficients
To balance write a coefficient and multiply
<span>3H2+N2--> NH3
H 2 x 3 = 6 H 3 (x2) = 6
N 2 N 1 (x2) = 2
Your answer is 2 . . . to balance this equation you will need a coefficient of 2</span>
Answer:
2
Explanation:
To balance the equation there must be the same numbers of atoms at the left side and at the right side. So, at the left side we have:
6 atoms of H (3 x 2)
2 atoms of N (1 x 2)
And at the right side we have:
1 atom of N (1 x 1)
3 atoms of HN (1 x 3)
If you multiply these last by 2, you will have:
2 atoms of N (2 x 1)
6 atoms of H (2 x 3)
Then, the numbers of atoms of H and N at the left side is equal to the numbers of atoms of H and N at the right side. The balanced equation is:
3H2+N2--> 2NH3
