Given the reaction 4NH3(g) + 5O2(g) = 4NO9(g) + 6H2O(g)
At constant pressure, how many liters of O2(g) would be required to produce 40 liters of NO(g)

Hey guys so i need to know what is _nh3+> nh4oh ~chemistry~

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.)
