Stoichiometry The weight fraction of methanol in an aqueous solution is 0.64. The mole fraction of methanol XM satisfies XM < 0.5 XM = 0.5 0.5 < XM < 0.64 XM ≥ 0.64 XM < 0.5 XM = 0.5 0.5 < XM < 0.64 XM ≥ 0.64 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Which of the following expressions defines the Baume gravity scale for liquids lighter than water? °Be = 145 - (145/G) °Be = 200(G-1) °Be = (400/G) - 400 °Be = (140/G) - 130 °Be = 145 - (145/G) °Be = 200(G-1) °Be = (400/G) - 400 °Be = (140/G) - 130 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The forces causing the vaporisation of liquid are derived from the Kinetic energy of translation of its molecules. The heat of vaporisation Decreases with increasing pressure Both B & C Becomes zero at the critical point Increases with pressure rise Decreases with increasing pressure Both B & C Becomes zero at the critical point Increases with pressure rise ANSWER DOWNLOAD EXAMIANS APP
