Question

10g of hydrogen and 64 g of oxygen were filled in a steel vessel and exploded .Volume of gaseous product after reactiond

Answer 1

H2 +O2-H2O 10gm H2 means 5mol and 64gm O2 means 2mol thus water formed would be liquid ..so 2 mol of O2 require 4mol of H2 and we have 5 mol of it and thus 1mol of H2 would be left after completion of reaction ..thus 2gm of H2 will be left in container after completion of reaction
