Stoichiometry (Gizmo) questions and answers 100% correct 1. A student tried to solve the following problem by selecting the tile as shown. What, if anything, did the student do wrong? B. The student chose the correct tile, but needs to flip the tile to make the units cancel 2. Based on the tiles, shown, how many moles of oxygen gas (O2) are needed to produce 36.04 grams of water (H2O) when reacting with access ethane in the equation: 2C2H6 + 7O2 —> 5CO2 + 6H2O? C. 2.3 moles of oxy...
