2 H2O2-> 2H20+02 2. What are the reactants in this reaction?
3. What are the products in this reaction?
4. What happened in this particular reaction? What happens in general decomposition reaction?

Explanation:

reactants --- hydrogen peroxide ( H2O2).products water ( H2O) and oxygen (O2).decomposition of hydrogen peroxide to water and oxygen.Reaction of decomposition of hydrogen peroxide is very slow in moderate temperatures without the presence of a catalyst [11]. It can be sped up by increasing the temperature, which triggers the reaction of thermal decomposition. This reaction can be carried out in a liquid or vapour phase. This reaction is exothermic.

hope this helps you.

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way

One splits the atoms and molecules  the other combines them
