Question

10 gram of hydrogen in 64 gram of oxygen were filled in a steel vessel and exploded amount of water produced in this reaction will be

Answer 1

2H2 + o2- 2h2o...so 10 gm H2 means 5mol and 64gm O2 means 2mol ...2 mol O2 require 4 mol of H2 thus O2 is limiting reagent and amount of H2O formed would be 4 mol thus 18×4=72 gm of H2O is produced
