500 ml of 1.0 M NaOH(aq) is added to 500 ml of 1.0 M HCl(aq) and the solution is quickly stirred. The rise in temperature (∆T1) is measured. The experiment is repeated using 100 cm3 of each solution and the rise in temperature (∆T2) is measured. (assume 4.18 J/g-oC and 1.00g/mL) It is found that: (a) ∆ T2 = 5∆T1; (b) ∆T1 = 5∆ T2; (c) ∆ T1 = ∆ T2; (d) ∆ T1 = 4∆ T2; (e) need to...
