What is the ∆g for the following reaction under nonstandard conditions for the formation of nh4no3( 2nh3(g) + 2o2(g)nh4no3(s) + h2o(l). given: . nh4no3: ∆hf = -365.56 kj ∆sf = 151.08. nh3: ∆hf = -46.11 kj ∆sf = 192.45. h2o: ∆hf = -285.830 kj ∆sf = 69.91

in this case its NH4NO3 or O2 can u check once again

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
