10 g of hydrogen and 32 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be

Options

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

Answer

D

Explanation

10 g of `H_2` = 5 mol and 32 g of `O_2` = 1 mol
` therefore ` In this reaction, oxygen is the limiting reagent so amount of `H_2 O` produced depends on amount of `O_2`.
Since 0.5 mol of `O_2` gives 1 mol `H_2 O`
` therefore ` 1 mol of `O_2` will give 2 mol `H_2 O`.
