Hydrogen peroxide decomposes as shown below: 2 H2O2 → 2 H2O + O2 molar mass H2O2 = (34.0 g/mol)   A sample of hydrogen peroxide solution was analyzed using the procedure from the “Enzymatic Decomposition and Analysis of Hydrogen Peroxide” experiment. A 7.54 g sample of the solution generated 0.0277 mol of oxygen gas.   Calculate the mass percent of H2O2 in the solution.

Which of the following represents the correct balanced chemical equation for the burning of coal which is still a major source of electricity in the United States.    A.  C + O --> CO  B.  C + O2 --> CO2  C.  C (s) + O (g) --> CO2 (g)  D.  C (s) + O2 (g) --> CO2 (g)

Check out the following video and write the balanced equation in this question. Hint: Remember to first determine the reaction type and then write products. There are two products to this reaction, and one is an ionic compound with potassium and chlorine and one is gaseous oxygen. Please make sure to use phases for each substance and parentheses (when needed) and subscripts. https://www.youtube.com/watch?v=fLic3zmH94s&feature=emb_title   (1 min 11 secs video)
