8.) What is the percent yield of H2 if 58.94g of methane and excess water yields 11.91gof H2 for the following reaction? CH4(g) + 2 H2O(g) → 4 H2(g) + CO2(g)What kind of reaction is this, according to the types we learned in this course?

The thermal decomposition of potassium chlorate follows the reaction: 4KCIO3 → 3KCIO4 + KCI After the reaction, 117.2 g of KCIO4 was found to be produced. If the reaction had a 84.8 % yield, how much (in grams) KCIO3 decomposed? (MW (g/mol): KCIO3 = 122.6, KCIO4 = 138.6, KCI = 74.6) Express your answer with 1 decimal place.
