Calculate the delta s rxn at 25 degrees celsius for the reaction 2nh3(g)-> > n2h4(g) + h2(g). do you know where i can find these values of the s for these compounds?

Why are the trends and exceptions to the trends in ionization energy observed?

What is the number of atoms in 3.54 mol s

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
