Ammonium perchlorate (nh4clo4) is the solid rocket fuel used by the u. s. space shuttle. it reacts with itself to produce nitrogen gas (n2), chlorine gas (cl2), oxygen gas (o2), water (h2o), and a great deal of energy. what mass of nitrogen gas is produced by the reaction of 9 gr of ammonium perchlorate? round your answer to significant digits.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
