what regent(s) would distinguish between
a) barium nitrate and lead nitrate solution?
b) copper (ii) nitrate and barium nitrate solution ?
c) silver nitrate and sodium nitrate solution ?
d) sodium nitrate and sodium sulfate solution ?

what cation would be present in a solution which forms a precipitate when added to sodium carbonate and sodium sulfate solutions but which gives no visible reaction with sodium chloride or sodium hydroxide solution

1. briefly explain why it would not be possible to distinguish between sodium nitrate and sodium acetate with the test scheme used in this experiment

a test tube contains a solutin of one of the followin salts NaCl, NaBr, and NaI describe a single test that can distinguish among these salts.

Given the following reaction: 2 KClO3(s) 2KClO3(s) + 3 O2(g)
What mass of KClO3 will produce 250mL of O2 gas, collected by water displacement, at an atmospheric pressure of 745 torr and a temperature of 30.0 C? The vapor pressure of water at 30.0 C is 31.8 torr.

How many mLs of H2 gas, collected by water displacement, are produced by the reaction of 0.500 g of Mg metal with an excess of HCl, at an atmospheric pressure of 750 torr and a temperature of 25.0 C? The vapor pressure of water at 25.0 C is 23.8 torr.
