Six 05 charge and impact theory composition

Does surface area affect dissolving of Alka-Seltzer tablets? Materials:

1 . solo cups of

2 . Alka-Seltzer tablets

a few. Timer

4. Testing Cup

5. Thermometer

Techniques:

1 . I located out two of my single cups on the counter

2 . However put a single cup of water into every cup. 3. Then set one Alka-Seltzer Tablet in a single cup and time this until it dissolves completely. 4. In the second glass I devote a crushed up Alka- Seltzer tablet and timed it until it finally dissolved. 5. Repeat actions 1 through 4 again.

Crushed Alka-Seltzer

21. 86 seconds

23. 52 secs

Whole Alka-Seltzer

29. 15 seconds

35. 33 just a few seconds

Discussion and Conclusion:

Answer the next questions in complete paragraphs.

1 ) What two factors did you look into in your method, and why did you choose to compare those two factors? Both the factors I actually investigated had been surface area and Alka-Seltzer. Choice to pick these if the surface area made the Alka-seltzer dissolves faster.

2 . What other factors did you should control during your investigation? Describe how you managed each one in your method.

Factors that I had to control in my experiment was your temperature of water, how many Alka-Seltzer tablets to set up, and how very much water to use in the cups. I had a thermometer to make certain that when I performed my two tests that they both equally had a similar temperature of water, I only put one tablet per glass, and I made

certain to have the same amount of water in each cup I actually used.

3. What was your prediction regarding the benefits of each element tested in your two research laboratory procedures? Describe your forecasts based on your understanding of the dissipating process, impact theory, and reaction costs. My forecasts of the outcomes on this lab were right. I figured that in case the Alka-Seltzer had been crushed up it would produce it more easier to dissolve since they had been in tiny pieces instead of one big tablet.

some. In your own words, explain the collision theory, and what is necessary for a collision to be successful? Collision theory is a theory that when elements collide in a certain way with the certain quantity of energy that they start to kind new chemicals.

5. A unique catalyst has not been provided for this reaction, yet catalysts are useful for increasing the rate of several slow reactions. In your own terms, give a comprehensive explanation of how catalysts may increase the level of a response or process? Catalysts may increase the price of a effect or procedure because that they help speed things up by minimizing the amount of strength required for the response to happen.
