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>

I believe that it would be the third option down.
Explanation:
The thermal energy is in constant motion in the COOLER room, and when the desired temperature in the room is reached, it stops.
Answer:
The rate of the forward reaction is equal to the rate of the reverse reaction
Explanation:
Equilibrium is a condition in which the net force for change is zero.
In chemistry, equilibrium exists when reactant concentrations in a reaction are not changing. This condition means the reaction proceeding left to right in the reaction equation is producing products at the same rate those products are being used up by the reaction proceeding right to left. In short, the rate of the forward reaction is equal to the rate of the reverse reaction.
An explosion is the only chemical reaction here- it would completely change the substance whereas with the others- every substance has a solid liquid and gas form so they would still be the same substance
