Question

About 5 mL of a 10% aqueous hydrogen peroxide (H_2O_2) solution was placed in a test tube. A few grains of solid (IV) oxide was then added to the same test tube. The acted as a catalyst. The glowing splint test was applied to the test tube as the reaction progressed the flame on the and also became (flared up. There was no sound produced the splint test. A liquid was observed to form as the reaction progressed. Write a balanced molecular equation for the decomposition replacement reaction that occurred. Points will be deducted for failure to indicate the state {(g), (i), (s), or (aq)} reactant and product species. The balanced molecular equation for the above decomposition reaction is:

Explanation / Answer

MgO(s)+H2O2(l)=MgO2(s)+H2O(l)

since they mentioned that there was no sound produced during the splint test so hydrogen gas is not evolved and it is mentioned that colour less liquid is formed that is nothing but water
