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

Options

A. 2 mol
B. 3 mol
C. 4 mol
D. 1 mol

Answer

C

Explanation

`H_(2) + (1)/(2)O_(2) to H_(2)O`
`(10)/(2) " " (64)/(32)`
= 5 mol = 2 mol
Oxygen is the limiting agent.
`because 1// 2O_(2)` gives = 1 moles of `H_(2)O`
`therefore 2O_(2)` will give = 4 moles of `H_(2)O`
