NH4Cl(s) → NH3(g) + HCl(g) ∆H0=176 kJ/mol ∆S0=0.285 kJ/(mol K) What can be deduced from to this reaction?

At room temperature, the reaction is not spontaneous. However, at high temperatures, like 800 °C, the free energy value turns negative and this reaction becomes spontaneous.

At room temperature, the reaction is spontaneous. If the temperature is increased, the free energy value turns negative and the reaction stays spontaneous.

At room temperature, the reaction is spontaneous. However, at high temperatures, like 800 °C, the free energy value turns negative and this reaction becomes nonspontaneous.

At room temperature the reaction is not spontaneous. However, at lower temperatures, like –40 °C, the free energy value turns negative and this reaction becomes spontaneous.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=

explanation:

the movement of aircraft through clouds can even cause lightning strikes. a single lightning event is a "flash", which is a complex, multi-stage explosively ejected.

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".
