Which of the following statements would be true if you have 50 molecules of both H2 and O, available for the reaction shown? 2H2(g) + O2(g) → 2H2O(g)
a. Hy is the limiting reagent and 50 molecules of water are formed.
b. O, is the limiting reagent and 100 molecules of water are formed.
c. neither H2 nor Oz is limiting
d. none of the statements are true

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

since electrons are negative the answer is neagtaive

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
