In this experiment, you will first change the temperature of the water and determine its effect on the time it takes the tablet to dissolve. Then you will alter the size of the antacid tablet and determine its effect on the time it takes the tablet to dissolve. In the space below, write a scientific question that you will answer by doing this experiment.
How do the factors of temperature and surface area affect the rate of chemical reactions? Which of the following did you include in your question?
Which of the following did you include in your question? Check all that apply.
Write a hypothesis about the effect of temperature and surface area on the rate of chemical reactions using this format: “If . . . then . . . because. . . .” Be sure to answer the lesson question, “How do the factors of temperature and surface area affect the rate of chemical reactions?”
If temperature and surface area increase, then the time it takes for sodium bicarbonate to completely dissolve will decrease, because increasing both factors increases the rate of a chemical reaction. Which of the following did you include in your hypothesis?
The independent variables, the ones that are intentionally manipulated, are ✔ temperature and surface areasurface area and reaction timeX temperature and reaction time.
