Predict whether each of the following reactions will occur in aqueous solutions. Explain your reasoning in each case. Note: Barium sulfate and silver bromide precipitate in aqueous solutions.
1) sodium hydroxide + ammonium sulfate → ?
reaction or no reaction?

2) niobium(V) sulfate + barium nitrate → ?
reaction or no reaction?

3) strontium bromide + silver nitrate → ?
reaction or no reaction?

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

the answer is c.the valence of the atoms combine .

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
