Background Information:
Terms: Citric Acid (C6H8O7), Molecules, Products, Reactants, Reaction Rate, Sodium Bicarbonate (NaHCO3), Solute, Solution, Solvent, Temperature.
• A chemical reaction is a process where a molecular or ionic structure of a substance rearranges.
• There are two parts to a chemical reaction called the reactants and the elements.
• Some signs of a chemical reaction are a change in change in color and bubbles. 
• In a chemical reaction, only the atoms present in the reactants can end up in the products. No new products or atoms are made in a chemical reaction.
• In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. The term aqueous solution is when one of the solvents is water. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent.
• The parts of a solution are a solute and solvent.
• A chemical reaction we use in real life is wood burning or the combustion of wood.

Hypothesis: I think the full tablet will have the fastest rate of a chemical reaction.]]> 2019-02-07 22:38:16 UTC https://padlet.com/e_swafford/ai587mm7b33s/wish/329012368 e_swafford https://padlet.com/e_swafford/ai587mm7b33s/wish/329012501 Procedures:
1) Assemble whatever materials are necessary for your testing procedures. 
2) Prepare the Alka-Seltzer tablets as necessary.
3) Drop the prepared solute into the solvent to test your "control" substance 
4) Time until the reaction stops and record time and observations.
5) Repeat steps 2-4 two more times for accuracy.
6) Repeat steps 2-4, but this time, prepare the "variable" substance (ie, you may be using the balance to measure out a substance, or may be using a different liquid, etc.)
7) Clean up lab station]]> 2019-02-07 22:38:44 UTC https://padlet.com/e_swafford/ai587mm7b33s/wish/329012501 e_swafford https://padlet.com/e_swafford/ai587mm7b33s/wish/329012576 Observations and Data Collection: the crushed alka seltzer, when dropped in water made smoke then disappeared. Also trials 2 and 3, we had to change the brand of the tablet and the newer tablet had a faster chemical reaction time than thew regular brand alka- seltzer.

Conclusion: I can conclude that that the half tablet of alka-seltzer had the longest time of chemical reaction. This means that my hypothesis is incorrect because I thought that the full tablet would have a longer time of chemical reaction because it was bigger, but I guess that was wrong by about 32 seconds. I can support my claim that the half tab had the longest time with test results trial 1, trial 2, and trial 3. In all the trials we used the same amount of water, but in trials 2 and 3 we ran out of our normal alka seltzer and used a of brand type tablet. It dissolved faster and it screwed up our testing. All in all, with my testing the half tablet of alka seltzer had the longest rate of chemical reaction time.]]> 2019-02-07 22:39:31 UTC https://padlet.com/e_swafford/ai587mm7b33s/wish/329012679 e_swafford https://padlet.com/e_swafford/ai587mm7b33s/wish/331848140 2019-02-15 18:06:52 UTC https://padlet.com/e_swafford/ai587mm7b33s/wish/331848140
