Suppose you have a box with red chairs and another with blue tables, both are made of smaller lego bricks. You pour the content of both boxes into a larger box and shake the box. You notice that, in the end: 1) Red and blue pieces became more evenly distributed throughout the box. II) Many chairs and tables had pieces of them break off. III) Sometimes, pieces stuck to each other forming all sorts of shapes, some containing both red and blue pieces. Are the changes described in items (I), (II) and (III), best compared to changes in entropy, enthalpy, or both? (1) Entropy only; (II) Entropy only; (III) Entropy only (1) Entropy only; (II) Enthalpy only; (III) Entropy only (1) Entropy only; (II) Both; (III) Both (1) Both; (II) Both; (III) Both (1) Entropy only; (II) Enthalpy only; (III) Enthalpy only

CHM 331A Lab 7 - 2021SP A. Heating of water In this experiment, you are given the results. You have to graph Time vs °C and experimentally determine and calculate the amount of heat necessary to heat water from room temperature to its boiling temperature. 1. 200 mL distilled water were measured , weighted and its mass recorded 2. Water was heated to boil, and its temperature recorded every minute. 3. At least 2-3 temperature points of boiling water were recorded in order to show good plateau when graphing the data as in the example below: 1401 gas 120 boiling- point 100- liquid and gas 80- boiling 60- Temperature (C) 40- liquid solid and liquid 0- 20- melting- point melting -20- solld -40- Time Mass of empty beaker 99.233 g Mass of beaker + water 226.31 g Mass of water Lab 7 pg. 3

[References] In a coffee-cup calorimeter, 100.0 mL of 1.1 M NAOH and 100.0 mL of 1.1 M HCl are mixed. Both solutions were originally at 20.3°C. After the reaction, the final temperature is 27.7°C. Assuming that all the solutions have a density of 1.0 g/cm" and a specific heat capacity of 4.18 J/°C g, calculate the ethalpy change for the neutralization of HCl by NaOH Assume that no heat is lost to the surroundings or to the calorimeter.
