Answer:
It would take 13 minutes.
Explanation:
The temperature decreases at a linear rate, meaning that we can describe the process by using the following formula:
Where T₂ is the final temperature, T₀ is the initial temperature; and t is the elapsed time in minutes.
We input the data given by the problem:
- 0 °C = 26 °C - 2°C/min * t
And solve for t:
Answer:
The flask has to be closed during the hydrochloric acid and sodium carbonate reaction as the resultant gas got trapped inside the closed flask.
Explanation:
The hydrochloric acid and sodium carbonate reaction was exothermic that caused the pressure to decrease. The flask has to be closed during the hydrochloric acid and sodium carbonate reaction as the resultant gas got trapped inside the closed flask.
In exothermic reactions, energy is produced in the form of heat or light.
