Your patient drank so much water that his blood became to his cells. This diagram best illustrates his cell and plasma osmolarity: The doctor has ordered a in which will raise the levels of your patient's blood. This diagram best illustrates the result. Because your patient's cells are to his blood, water will move by causing his tissues to Because your patient's cells are now to his blood, water will begin to move the cells by causing the cells to

A) Less than 90 C B) More than 90 C C) 90 C D) Need to know what solvent Z to answer question E) 90 K 10 pts Answer must contain the correct number of sig figs. 0.150 kg - 519.5 g = ? 10 pts Freezing point of solvent X is -5 C. 30 g of NaOH is added to solvent X resulting in a homogeneous solution. What is the Freezing point of the solution? Multiple choice. A) Less than -5 C B) More than -5 C C) -5 C D) Need to know what solvent X to answer question E) 0 C 15 pts Calculate $\Delta H^\circ$ for the process P(s) + 7/2 F$_2$(g) $\rightarrow$ PF$_5$(g) $\Delta H^\circ$ = ?? ______ kJ PF$_3$(g) $\rightarrow$ PF$_5$(g) + 2F$_2$(g) $\Delta H^\circ$ = 75 kJ P(s) + 3/2 F$_2$(g) $\rightarrow$ PF$_3$(g) $\Delta H^\circ$ = -414 kJ
D. Each electron passing through the deflection plates feels the electric force for a time Δt which you calculated above. What are the resulting vertical velocity y and deflection angle? Show your work and equations below. y = √(2qV/m) * Δt θ = tan^(-1)(y/L) E. This deflection angle occurs at a distance L = 0.16 m from the screen. What is the resulting vertical deflection Dy = y at the screen for V_y = 1.0 volt? Show work below, including a sketch. F. Compare with the measured deflection per volt and calculate the relative error for your measured value, in %: [(measured - calculated) / calculated] * 100
