The balanced equation shown below has a 81.3% yield, and you need to collect 91.3 grams of CO2. How many grams of C3H6 should you burn? 2C3H6 + 9O2 → 6CO2+ 6H2O

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

Can someone me with 3 and 4 plz. this is for masteries test.
