Remaining Time! 02:29:4. Consider the balanced chemical equations shown below. When a 6.00 g sample of a mixture of iron (Fe) and aluminum (Al) is treated with excess HCl(aq), 0.177 moles of H2 are obtained. What is the mass percentage of Fe in the original mixture? Choose the closest answer. Fe(s) + 2 HCI(aq) FeCl2(aq) - + H2(g) 2 Al(s) +6 HC((aq) 2 AICI3(aq) + 3 H2(g) 96 % 69 % 47 % 33 % 17 % Rack Question Menu - O O
Try Again Your answer is incorrect. • Row 1: Your answer for change in composition column is incorrect. • Row 2: Your answer for change in composition column is incorrect. Sulfur dioxide and oxygen react to form sulfur trioxide, like this: 2 SO₂(g) + O₂(g) → 2 SO 3(g) The reaction is exothermic. Suppose a mixture of SO₂, O₂ and SO3 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation The temperature is lowered. change in composition The pressure of SO₂ will The temperature is raised. The pressure of SO3 will go up. go up. ↑ shift in equilibrium to the right to the left (none) to the right to the left (none)
