Qu12 1SLI uctiuIS Question 6 A material that partially dissociates in water an conducts electricity poorly is called: O Astrong electrolyte O An alcohol A weak electrolyte O None of the above A non-electrolyte Previous Quiz saved at 1:2

Answer 1

6) It is a weak electrolyte. Option C.

11) Option A. The reaction that occurs is:

4 H2 + 2 O2 = 4 H2O

Is calculated:

ΔH = (4 * -285.83) - (4 * 0) - (2 * 0) = -1143.2 kJ

12) Propane moles are calculated:

n = m / MM = 100 g / 44.1 g / mol = 2.27 mol

The heat released is calculated:

q = ΔH * n = -2219.15 * 2.27 = - 5043.53 kJ

Option E.

17) Option B. A non-electrolyte.

If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.
