Is my answer correct? refer to the phase diagram of substance x. which statement below is not true about the diagram? 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. “ c. substance x is undergoing a change from a liquid to a gas at the line shown by e. * this is my answer* d. substance x is a liquid in the area shown by "2".

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.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
