Answer: It is important to conduct multiple trials so one can get the best results, additionally, multiple trials with result in minimal errors. Finally it is important to conduct multiple trials because it will show you the actual answer/solution/whatever. If you do something once their may of been a random unknown affect and you would of never knew because you only conducted the experiement once.
Explanation:
Hello, let me break this down for you! :)
A is your energy of your reactants, B is your activation energy, so the
total value could be found from B-Y. C is the value of your energy of
your products. X is your delta H value. So in this, your products are
higher energy than the reactants, so H is + and e2-E1 is positive so E2
>E1
Therefore your answers would just be <span>E2 > E1 and
</span><span>Hrxn<span> is positive.
Hope this helps! If you have any other questions or need further explanation just let me know! :)

Answer:
The percentage yield of LiOH is 39.9%
Explanation:
From the question given above, the following data were obtained:
Theoretical yield = 47.4 g
Actual yield = 18.9 g
Percentage yield =?
The percentage yield of LiOH can be obtained as follow:
Percentage yield = Actual yield / Theoretical yield × 100
Percentage yield = 18.9 / 47.4 × 100
Percentage yield = 1890 / 47.4
Percentage yield = 39.9%
Therefore, percentage yield of LiOH is 39.9%
