If 50.0 grams hydrogen peroxide produce 15.0 g oxygen, what is the percent yield for this reaction? 2H2O2 (l) → 2H2O(l) + O2(g)

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.

Answer explain why it is not possible to deduce a complete order of reactivity.

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m
