Minimum m.w. rarr molecule at least contain one selenium. 10 g of hydrogen and 64 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be

Answer»

2 mol
3 mol
4 mol
1 mol

Solution :`{:(H_(2),+,1/2 O_(2) rarr H_(2)O),(10/2,,64/32),(="5 mol",,="2 mol"):}`
Oxygen is the limiting agent.
`:' 1//2O_(2)` gives `=1` mole of `H_(2)O`
`:. 2O_(2)` will give `=4` moles of `H_(2)O`.
