How are the conditions at which phases are in equilibrium represented on a phase diagram?
Image result for How are the conditions at which phases are in equilibrium represented on a phase diagram?
Along the line between liquid and solid, the melting temperatures for different pressures can be found. The junction of the three curves, called the triple point, represents the unique conditions under which all three phases exist in equilibrium together. Phase diagrams are specific for each substance and mixture.

Answer: Option C) 4 moles
Explanation:
The reaction below shows the decomposition of 2 moles of water to yeild 2 moles of hydrogen and 1 mole of oxygen respectively.
2H2O(l) --> 2H2(g) + O2 (g)
So, if 2 moles of H2O produce 1 mole of O2
8 moles of H2O will produce Z mole of O2
To get the value of Z, cross multiply
2 x Z = 1 x 8
2Z = 8
Z = 8/2
Z = 4
Thus, 4 moles of O2 is produced from the complete decomposition of 8 moles H2O .
