A \( 98.2 \mathrm{~mL} \) sample of \( 1.00 \mathrm{MNaOH} \) is mixed with \( 49.1 \mathrm{~mL} \) of \( 1.00 \mathrm{MH}_{2} \mathrm{SO}_{4} \) in a large Styrofoam coffee cup: the cup is fitted with a lid through which passes a calibrated thermometer. The temperature of each solution before mixing is \( 22.85^{\circ} \mathrm{C} \). After adding the \( \mathrm{NaOH} \) solution to the colfce cup and stirring the mixed solutions with the thermometer, the maximum temperature measured is \( 30.30^{\circ} \mathrm{C} \). Assume that the density of the mixed solutions is \( 1.00 \mathrm{~g} / \mathrm{mL} \), that the specific heat of the mixed solutions is \( 4.18 \mathrm{~J} /\left(\mathrm{g}^{\circ} \mathrm{C}\right) \), and that no heat is lost to the surroundings. 14 th attempt Part 1 (1 point) Feedback Write a balanced chemical equation for the reaction that takes place in the Styrofoam cup. Remember to include phases in the balanced chemical equation. \[ \mathrm{H}_{2} \mathrm{SO}_{4}(a q)+2 \mathrm{NaOH}(a q) \longrightarrow \mathrm{Na}_{2} \mathrm{SO}_{4}(m q)+2 \mathrm{H}_{2} \mathrm{O}(t) \] Is any \( \mathrm{NaOH} \) or \( \mathrm{H}_{2} \mathrm{SO}_{4} \) left in the Styrofoam cup when the reaction is over? Choose one: A. Yes B. No Part 3 (1 point) * Feedback Calculate the enthalpy change per mole of \( \mathrm{H}_{2} \mathrm{SO}_{4} \) in the reaction. \( \mathrm{kJ} / \mathrm{mol} \)
