Create a scatter plot using the data in Data Table 2. Plot time on the independent axis (x-axis) and temperature on the dependent axis (y-axis). Add a linear trendline that represents temperature change. Extend the trendline to the y-axis, time "0". The extrapolation at the "0-second time" most likely represents the "maximum temperature from the reaction." Compare the extrapolated temperature to the initial recorded temperature of the mixture and record the greater of the two temperatures in Data Table 1 as the highest temperature of the mixture. **Data Table 2: Temperature of Solution Every 20 Seconds**| Time after mixing (min:sec) | Temperature (°C) ||-----------------------------|------------------|| Initial | 26.7 || 0:20 | 30.5 || 0:40 | 30.8 || 1:00 | 30.7 || 1:20 | 30.6 || 1:40 | 30.7 || 2:00 | 30.8 || 2:20 | 30.7 || 2:40 | 30.6 || 3:00 | 30.5 || 3:20 | 30.3 || 3:40 | 30.1 || 4:00 | 30.0 || 4:20 | 29.7 || 4:40 | 29.6 || 5:00 | 29.5 |This table displays the temperature of a solution recorded every 20 seconds over a period of 5 minutes.

Create a scatter plot using the data in Data Table 2. Plot time on the independent axis (x-axis) and temperature on the dependent axis (y-axis). Add a linear trendline that represents temperature change. Extend the trendline to the y-axis, time "0". The extrapolation at the "0-second time" most likely represents the "maximum temperature from the reaction." Compare the extrapolated temperature to the initial recorded temperature of the mixture and record the greater of the two temperatures in Data Table 1 as the highest temperature of the mixture.

This table displays the temperature of a solution recorded every 20 seconds over a period of 5 minutes. The temperature, measured in degrees Celsius, is noted next to each time interval. You can observe changes and trends in how the solution's temperature shifts over time after the initial mixing.

**Data Table 1: Temperature (°C) of the Solution (NaOH + HCl)**

- **Initial Temperature of NaOH (°C):** 23.0
- **Initial Temperature of HCl (°C):** 23.3
- **Average Initial Temperature of Two Separate Solutions (°C):** 23.2
- **Highest Temperature of Mixture (May Be Extrapolated from Graph) (°C):** [Blank]
- **Change in Temperature of Mixture (°C), ΔT:** [Blank]

Explanation:
This data table represents the initial temperatures of two separate solutions, NaOH and HCl, used in an experiment. The average initial temperature is calculated from these values. The table also provides slots for recording the highest temperature of the mixture, which might require extrapolation from a graph, and the change in temperature of the mixture, ΔT, but these fields remain unfilled.
