As you can search and read the definition of a scientific experiment is the process of testing and finding the truth through this scientific method. Thus, all items are considered scientific experiment except for item "c" Ask her coworkers which solution they thick is better.
I believe that the correct answer would be energy since you need energy for any kind of chemical change to occur. I hope this helped you with your question! If you have any questions please let me know and I might be able to further assist you.
As,
Kw = [H+] [OH-]
For water, [H+] = [OH-]
Therefore we can write
Kw = [H+]²
9.311 × 10-14 = [H+]²
[H+] =
3.04 × 10-7 = [OH-]
Ph = - log [H+]
= - log (
3.04 × 10-7)
= 6.52
Thus, Ph = PoH = 6.52
Percent yield is calculated using:
Your actual yield is how much you actually had at the end of the experiment = 79g.
Your theoretical yield is how much you calculated you should have gotten in an ideal, perfect experiment = 104g.
So put those values into the equation:
Before answering the question, one should first calculate the pH for given concentration of LiOH.
As LiOH ionizes as,
LiOH → Li⁺ + OH⁻
So, the concentration of OH⁻ = [OH⁻] = 0.01
Also,
pOH = -log [OH⁻]
pOH = -log [0.01]
pOH = 2
Whereas,
POH + pH = 14
Or,
pH = 14 - 2
pH = 12
Result:
As pH is greater than 7, so the solution is Basic.
