When (30 ~mL ) of ( H ₂ ) reacts with (20 ~mL ) of ( O ₂ ) to form water, what is leftover when the reaction ends?
Options
- A(10 mLH ₂ )
- B(5 mLH ₂ )
- C(10 mLO ₂ )
- D(5 mLO ₂ )
Correct answer
D. (5 mLO ₂ )
Step-by-step solution
Given Here, ( H ₂ ) is the limiting reagent. So, (30 ~mL H ₂ ) consumes (15 ~mL ) of ( O ₂ ) as ( H ₂ ) and ( O ₂ ) react in (2: 1 ) volume ratio (at constant pressure and temperature).
