Answer:
7.4.
Explanation:
∵ pH = -log[H₃O⁺].
∴ pH = -log(2.5 x 10⁻⁷) = 6.6.
<em>∵ pH + pOH = 14.</em>
<em />
∴ pOH = 14.0 - pH = 14.0 - 6.6 = 7.4.

Answer:
Work = Path function.
Energy = State function.
Distance traveled = Path function.
Enthalpy = State function.
Heat = Path function.
Explanation:
Hello,
At first, a state function is a property whose value does not depend on the path taken to reach that specific function or value, as in this case, energy and enthalpy.
On the other hand, path functions are functions that depend on the path taken to reach that specific value, as in this case, work, distance traveled and heat since different paths will provide different values for each one of them.
Best regards.
You could use percent error. Absolute | | of accepted value minus experimental value \ divided by accepted value multiply by 100 and that is your answer
In order to calculate the amount of heat energy required to melt 347 grams of ice, we need to will apply the equation:
Q
= ml, where m is the mass of substance and l is its latent heat of
fusion. For ice, the latent heat of fusion is 334 joules per gram.
Therefore:
Q = 347 x 334
Q = 112,558 joules of energy
Hope this helped.
