Ответ:
A solubility curve is a data based graph comparing the amount of solute that will dissolve in a given amount of solvent at various temperatures.
Ответ:
241.82 kJ is released
Explanation:
The reaction indicates that 483.64 kJ of energy is released when TWO moles of H2O(g) is formed. You're looking to find the amount of energy released when only ONE mole of H2O forms, so that would be half the amount of energy released in the reaction (as one mole is a half of two).
483.64 / 2 = 241.82 kJ
So, your answer would be 241.82 kJ is released.
