If I add water to an  alka seltzer how much chemical reaction will happen, how will lemon juice and soda compare to water how much chemical reaction happens with the alka seltzer.

Background Info: A chemical reaction is when the rearrangement of molecules happens. A chemical reaction has two parts the first is the elements and the compounds and the second is what is the product. You can tell if chemical reaction is happening by it bubbling or changing color, also their is formation of gas, formation of precipitate, odor change and temperature change those details of when a chemical reaction has occurred. Chemical reactions make a new product because the atoms break apart and make a new product but no new atoms are made and no atoms are destroyed. A solution is a mixture of two or more substances an example of this is salt and water mixing together. We use chemical reaction everyday of our lives like the rusting of iron is a example when a bike gets wet rust will start to grow on it. Also the burning of wood is a good one because it is a formation of a gas a change in odor and temperature change. Finally another one using an alka seltzer it is bubbling and formation of a gas.

Hypothesis: If we use the lemon juice and soda their will not be as much chemical reaction that water had because the CO2 in the soda would make the alka seltzer dissolve quicker and the acid in the lemon juice would do the same thing.

Control: The size of the Alka Seltzer
Variable: The liquid used for the project

1. we want to grab cups paper towels and Alka Seltzers
2. Then fill the cups up with the liquid you are doing it with
3. after that you want to grab your timer and your Alka-Seltzer
 4. you want to drop your Alka- Seltzer into the liquid you are using and time how long the chemical reaction is
5. you record your answer then put it on your graph and repeat 3 times to get a reliable graph

The number told us that soda was the highest chemical reaction the average was the lemon juice and the lowest was the water. My hypothesis was incorrect because the soda and lemon juice both had a higher chemical reaction than the water did. A fault that may have affected our experiment was if we didn't time it correctly like it not dissolving all the way or losing sight of it in the liquid. I've learned that chemical reaction can happen for many things in life that we probably didn't know.
Conclusion: Are project showed chemical reaction with the change of a liquid. It proved my hypothesis wrong because the soda and the lemon juice both had the longest chemical reaction. WIth this we can prove that chemical reactions happen longer with lemon juice and soda instead of water.]]> 2019-02-06 18:41:27 UTC https://padlet.com/m_ruiz2/z244xabzqcb7/wish/328426505 Domain 3 collecting and presenting data m_ruiz2 https://padlet.com/m_ruiz2/z244xabzqcb7/wish/331847181 Data Table
Observation: Everytime we dropped an alka seltzer in it fizzled till it was dissolved away in the liquid and we would record how long it took. The longer it took the more chemical reaction.]]> 2019-02-15 18:04:25 UTC https://padlet.com/m_ruiz2/z244xabzqcb7/wish/331847181 Domain 3 m_ruiz2 https://padlet.com/m_ruiz2/z244xabzqcb7/wish/331847568 Data Graph
