Add missing schemes of equations, arrange coefficients, determine the type of reactions. H202-H2O + O2

Consider the reaction that is given to us in the task. Given substance hydrogen peroxide, chemical formula Н2О2. The given reaction is the reaction of dissociation or decomposition of a more complex substance into simpler ones. In our case, hydrogen peroxide decomposes into water and oxygen. In order to equalize the reaction, we need to put the number 4 in front of hydrogen peroxide, in the reaction products we put 4 in front of water, and in front of oxygen we put 2. Graphically, this chemical reaction equation can be expressed as follows:

4 H2O2 = 4 H2O + 2 O2.
