First, we need to balance the equation given in the question. The balanced equation is: 2I₂ + 5F₂ → 2IF₇ Next, we need to find the limiting reactant. We have 25.0 g of fluorine, so we need to convert it to moles: 25.0 g F2 / (2 x 18.9984 g/mol) = 0.658 mol F2 Now we can use stoichiometry to find the theoretical yield of IF₇: 0.658 mol F2 x (2 mol IF₇ / 5 mol F2) x (253.808 g/mol) = 48.9 g IF₇ Therefore, the maximum amount of IF₇ that can be obtained is 48.9 g. Choice B is the correct answer.

Use the Equation NH3 + O2 → NO + H2O

Use the Equation NH₃ + O₂ → NO + H₂O
