One of the steps in the commercial process for converting ammonia to nitric acid involves the conversion of NH3 to NO:
NH3 (g) + O2 (g) ? NO (g) + H2O (g)
a)How many grams of NO form when 1.50 g of ammonia reacts with 1.85 grams of oxygen?b)Which reactant is the limiting reagent and which is the excess reagent?
When 9 mL of a solution containing 2.5 M AlBr3 is diluted to 30 mL, a dilute solution is formed. What is the Br- concentration in 15 mL of the dilute solution?
Sodium chlorate,NaClO3, decomposes when heated to yield sodium chloride and oxygen, a reaction used to provide oxygen for the emergency breathing masks in many airliners
Up to Iron "Fe", the number of proton and neutron are about equal, after Fe the number of neutron began to rapidly increase, with respect to the number of proton, why?
