In a space alien cell with a membrane potential of -70mV, anion A equilibrium potential is -84mV, anion B equilibrium potential is 88mV, and cation C+ equilibrium potential is -48mV. All three ions are moving through channels, and are the only three ions moving through the membrane (so they determine membrane potential, so this cell must lack typical leak channel biology). Anion A is [Select] (circle one) the cell with a [Select] driving force. Anion B is [Select] (circle one) the cell with a [Select] driving force. Cation C+ is [Select] (circle one) the cell with a [Select] driving force. Resistance to the flow of ion [Select] is the lowest in this scenario.

A 0.617 mol sample of CO2 (g), initially at 298 K and 1.00 atm, is held at constant pressure while enough heat is applied to raise the temperature of the gas by 13.5 K. Calculate the amount of heat q require to bring about this temperature change, and find the corresponding total change in the internal energy delta U of the gas. Assume that the constant-pressure molar specific molar specific heat for CO2 (g), which consists of linear molecules is equal to 7 R/2, where R=8.3145 J?(mol x K) is the ideal gas constant

The \( \mathrm{p} \mathrm{K}_{\mathrm{a}} \) of acetic acid, \( \mathrm{CH}_{3} \mathrm{COOH} \), is 4.74 . A buffer solution was made using an unspecified amount of acetic acid and 0.30 moles of \( \mathrm{NaOOCCH}_{3} \) in enough water to make \( 2.00 \mathrm{~L} \) of solution. The \( \mathrm{pH} \) of the solution is 4.40 . How many moles of \( \mathrm{CH}_{3} \mathrm{COOH} \) were used? Select one: a. \( \quad 0.14 \mathrm{~mol} \) b. \( \quad 0.18 \mathrm{~mol} \) c. \( 0.66 \mathrm{~mol} \) d. \( \quad 0.55 \mathrm{~mol} \)
