Combustion of Methane Methane gas burns to produce carbon dioxide gas and gaseous water. –Whenever something burns it combines with O 2 (g). CH 4 (g) + O 2 (g) CO 2 (g) + H 2 O(g) If you look closely, you should immediately spot a problem.
Practice — How many moles are in 50.0 g of PbO 2 ? (Pb = 207.2, O = 16.00) because the given amount is less than g, the moles being < 1 makes sense 1 mol PbO 2 = g 50.0 g mol PbO 2 moles PbO 2 Check: Solution: Conceptual Plan: Relationships: Given: Find: g PbO 2 mol PbO 2 93 Tro: Chemistry: A Molecular Approach, 2/e
