Question

In the reaction 2H2O2 -> 2H2O + O2, if you start with 4 H2O2, how much O2 will you end up with?

A 4
B 3
C 2
D 1

Answer 1

Option C) 2.

Step-by-step explanation:

• 2H₂O₂ gives 2H₂O and O₂ .
• When 4H₂O₂ is taken 2O₂ is produced, this can be simply explained by balancing the entire equation.
• 4H₂O₂ --------> 4H₂O + 2O₂ .
• On balancing the equation when taking 4H₂O₂ we get 4 H₂O and 2O₂.
• Where H₂O₂ is called hydrogen peroxide which is a unstable compound, and H₂O is water and O₂ is oxygen gas.

Result: 4H₂O₂ will produce 2O₂ .
