Yes you are right .. X is undergoing a change from solid to gas at point E
Olin [163]3 years ago

Yes you are right as from the phase diagram it can be seen :

A. Substance X is in the solid phase in the area shown by “1”.


B. Substance X exists as a solid, a liquid and a gas at point D.

D. Substance X is a liquid in the area shown by "2"

But the point C is not correct as Substance X is not undergoing a change from a liquid to a gas at the line shown by E while it undergoes a phase change from solid to gas.

What is the maximum mass of s8 that can be produced by combining 89.0 g of each reactant?
lidiya [134]

Answer : We can produce 125.7 g of S_{8}.


Explanation : The reaction will be

8SO_{2} + 16H_{2}S -----> 3S_{8} + 16H_{2}O


The molecular mass of SO_{2} is 64.1 g/mol

and molecular mass of H_{2}S is 34.1 g/mol


For every mole of SO_{2} we would need twice of H_{2}S moles, so for every 3 moles of S_{8} we need 16 moles of H_{2}S


Now, we can calculate number of moles S_{8}

2.61 X (3/16) = 0.49 moles


Here, the molecular mass of S_{8} is 256.8 g


multiplying it with the number of 0.49 moles we get, 256.8 X 0.49 = 125.7 g of S_{8}.


Hence, 125.7 g of S_{8} will be produced.
