Consider a cell membrane at 298k. the ca2 is at a concentration of 0.002 mm inside the cell and 0.4 mm outside the cell, with the voltage being 25mv higher in the interior. calculate the molar free energy difference for transporting ca2+ from the exterior to the interion a. 8.8 kj/molb. -13.6 kj/mol c. -17.9 kj/mol d. -18.4 k/mol

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

b.

the accuracy of the data.

i don,t know so just answer mine
