Question

Hydrogen peroxide is a chemical used to clean bacteria out of cuts. it does this through creating germ-eating oxygen in this decomposition reaction. what set of coefficients, respectively, balance this equation? h2o2 → h2o + o2

Answer 1

OK its B

2 → 2,1 Start by balancing the O, by putting a 2 in front of H2O (this gives an even number of O). This creates a total of 4 O on the product side and 4 H. To balance the H, put a coefficient of 2 on the reactant side.

Answer 2

Balancing a chemical reaction is a consequence of following the nature's law of conservation of mass. The concept is to keep the amount of a certain element the same before and after the reaction. For example, if there are 2 atoms of O in the reactant side, the product side should also contain 2 O atoms. With that being said, the complete balanced reaction is as follows:

2 H₂O₂ → 2 H₂O + O₂
