Consider the following reaction at constant P. Use the information here to determine the value of Ssurr at 355 K. Predict whether or not this reaction will be spontaneous at this temperature. Question 7 options: Ssurr = +114 kJ/K, reaction is spontaneous Ssurr = +114 kJ/K, reaction is not spontaneous Ssurr = +321 J/K, reaction is spontaneous Ssurr = -321 J/K, reaction is not spontaneous Ssurr = +321 J/K, it is not possible to predict the spontaneity of this reaction without more information.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

a corroding iron, if that's one of your choices

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
