**CHM 331A Lab 7 - 2021SP**### A. Heating of WaterIn 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, weighed, 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 to show a good plateau when graphing the data, as in the example below:#### Graph Explanation:- **Y-axis (Temperature °C):** Ranges from -40°C to above 120°C.- **X-axis (Time):** Represents the time taken for heating.- **Phases:** - Starts at the **solid** phase, increases toward melting. - Shows the **melting point** where solid transitions to liquid. - As temperature increases, water becomes **liquid**. - Reaches **boiling point** where liquid transitions to gas. - A plateau is observed at the boiling point, indicating a phase where both liquid and gas exist.#### Recorded Mass:- **Mass of empty beaker:** 99.233 g- **Mass of beaker + water:** 226.31 g- **Mass of water:** ____ g*Note: Calculate the mass of water by subtracting the mass of the empty beaker from the mass of the beaker with water.***End of Lab 7 pg. 3**

In a coffee press, you combine solid coffee grounds and hot water. After a long time, the ground coffee beans are still visible, and the water has turned into a rich dark brown (some of the coffee has dissolved into the liquid). You push the filter in the press down and pour out only the dark water into a cup. You then add milk and sugar to the cup. You also notice that the filter must have a hole in it because there are coffee grounds also in your cup. Calculate the degree of freedom in this system (your cup) at equilibrium. 1 2 3 4

Use the following data to answer part A: mixing NaOH(s) into plain water released 1541 J of heat mixing NaOH(s) into HCl(aq) released 3498 J of heat mixing NaOH(aq) into HCl(aq) released 2000 J of heat Show that this data either supports or contradicts Hess’s Law and be clear in your explanation by using chemical equations and numerical calculations. Assume that all three parts use the same amount of NaOH and for the two parts using HCl(aq), the same amount of HCl was used as well. Hint: The sign of your values are important.
