Question

When the following equation is balanced the coefficients are?

Al(NO3)3 + Na2S --> Al2S3 + NaNO3
A. 1, 1, 1, 1
B. 2, 3, 2, 3
C. 2, 1, 3, 2
D. 4, 6, 3, 2
E. 2, 3, 1, 6

Answer 1

The balanced coefficients for the equation Al(NO3)3 + Na2S → Al2S3 + NaNO3 are E) 2, 3, 1, 6.

Step-by-step explanation:

The balanced coefficients for the equation

Al(NO3)3 + Na2S → Al2S3 + NaNO3

are 2, 3, 1, 6. To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation.

Here's how the equation can be balanced:

• 2 Al(NO3)3 + 3 Na2S → 1 Al2S3 + 6 NaNO3

All elements are now balanced, and the coefficients are in the simplest whole-number ratio. Therefore, option E. 2, 3, 1, 6 is the correct choice.
