DescriptionA chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.
Description:
<span>"0.0400 mol of H2O2 decomposed into 0.0400 mol of H2O and 0.0200 mol of O2."
This means that a certain amount of H2O2 (0.0400 mol) decomposed or was broken down into two components, 0.04 mol of H2O and 0.02 mol of O2. To examine the system, we need a balanced equation:
H2O2 ---> H2O + 0.5O2
The final concentrations of the system indicates that the system is in equilibrium. </span>
Why you saying we can download an answer we’re here for an answer
This reaction contains pure solids which are not considered when writing out equilibrium constant expressions.
O2...........SO2
I 2.9...........0
C -x.......... +x
E 2.9-x........ x
Q=0/2.9 = 0 ---->Q<K Reaction will go to the right
Since the coefficients are all 1, I won't bother putting in the exponents.
k=B/A
1.5= x / (2.9-x)
4.35 - 1.5x = x
2.5x = 4.35
x= 1.74
plug back in ice chart
2.9 - 1.74
=1.16
=1.2 ANSWER
