The answer is <span>polarized </span><span>state.</span>
Given:
The solution decreased by ounces every hour for 5 hours.
Remaining solution at the end of the experiment = ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by ounces every hour for 5 hours.
Total decreased amount
Initial amount = Remining amount + Decreased amount of solution.
Therefore, the initial amount of solution is 18 ounces.
