D Pa O CHEMICAL REACTIONS Solving for a reactant using a chemical equation - 0/5 A major component of gasoline is octane (C3H18). When octane is burned in air, it chemically reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H,). What mass of oxygen gas is consumed by the reaction of 2.26 g of octane? Be sure your answer has the correct number of significant digits. ?

For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that NH3 is a weak base. Julianna acids: 0.4 mol of HNO3 is added to 1.0 L of a 0.8M NH3 bases: solution. ☐ other: ☐ 0.1 mol of NaOH is added to 1.0 L of a solution that is 0.3M in both NH3 and NH,C1. ☐…
