Chemistry

A 70.0mL sample of 1.0 M NaOH is mixed with 44.0 mL of 1.0 MH2SO4 in a large Styrofoam cup; the cup is fitted with a lidthrough which passes a calibrated thermometer. The temperature ofeach solution before mixing is 23.9 Celcius. After adding the NaOHsolution to the coffee cup, the mixed solutions are stirred untilreaction is complete. Assume that the density of the mixedsolutions is 1.00 g/mL, that the specific heat of the mixedsolutions is 4.18 J/(g celcius), and that no heat is lost to thesurroundings. The deltaHrxn for the neutralization of NaOH withH2SO4 is -114 kJ/mol H2SO4. What is the maximum measuredtemperature in the Styrofoam cup?

Ans Moles of NaOH Molarity x volume in Liters of NaOH solution 10 M x 0070 L 0070 moles Moles of H2SO4 Molarity x volume in Liters of NaOH solution 10 M x 0044 L 0044 moles Since 1 mol H2SO4 gives 2 moles H or H3O ions H2SO4aq 2 Haq SO42aq total moles of H from H2SO4 2 x moles of H2SO4 2 x 0044 moles 0088 moles Now we have Moles of OH from See Answer
