Question

the first photo is the data I collected, can you help me fill the second photo? third photo is information you might need to do so.

C. Heat of Reaction Original temp of HCl Onginal terms of No Oth, Final temp. of neutralized 21.5°C 21.8°C 25.2°C 22.1°C 21.6°C 25.5°C

25 ml of HCl and NaOH each

Answer 1

the heat of neutralisation reaction 4+62) + oH (aq) — H2O() For trial 1 The average initial solution before the neutralisation of Hel & Noot = Ź[ 21.5 + 21870 - 21-65°C Fimal temperature of the solution mixture after the neutralisation reaction =25-2°C 21.65€ 25.2°C So, heat is gained by the solution reaction of after the neutralisation this heat is coming from neutralisation reaction. Here, heat gained by the solution mixture Cat) = heat released by the neutralisation reaction (204) Now, 900 MH2O X CAGO XAT where, men mass of water som = 50g . Che specific heat of water = 4:184 I/ gre Firmal temp (T) – Guitial temps Ti) - (252 –21.65)°C - 355 :: 2420: sogx 4:184 1 4 3554. = 74266 J :: AH = 742 66 I :: AH = -742-46 ; (for trial 1) AT-temperature change.

Similarly for trialz. Average initial temperature (T:) = 25221+21672 = 21.85 (1)-255 final tenperature - 17 = (T-T;) - (25.5 - 21.85)•C-365°C ": 3, 4, x C4, 4 X AT. – 50x4184x 3.65 J = 563 585 (for tria12).
