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

Option C) 2.

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 .
