Signs of a chemical reaction are a change in color, formation of precipitate, formation of gas, odor change, and temperature change. Chemical reactions usually cannot be undone. A chemical reaction happens when a solute come in contact with a solvent with some form of energy. When theses two react together they make a solution. A solution is a new arrangement of molecules caused by reactants making a product. The parts of a solution are the solute and the solvent. This can be seen in real life when a cake is baked. The materials in the cake react with each other, and the heat releases carbon dioxide gas in the cake making the cake rise.]]> 2018-03-02 17:24:08 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/237509930 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/237516067 If I put a Alka-seltzer inside two beakers, one beaker with hot water, the other beaker with cold water, the Alka-seltzer will dissolve faster in the hot water because I know chemical reactions happen faster in heat rather then in cold.]]> 2018-03-02 17:36:40 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/237516067 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/237517902 How does the temperature of water affect the rate of chemical reaction?]]> 2018-03-02 17:40:17 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/237517902 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/237519911 - One stopwatch
- One 600ML beaker
- Access to running water (Hot/cold)
- Six Alka-seltzer tablets]]> 2018-03-02 17:44:21 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/237519911 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/237523250 2018-03-02 17:50:45 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/237523250 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/238436803 2018-03-06 03:04:48 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/238436803 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/238442801 2018-03-06 03:42:20 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/238442801 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/265044571 In my results I have found my hypothesis to be true and that if I put an Alka-Seltzer in two different temperature waters, the hotter water 
will dissolve the Alka-seltzer faster than the colder water. This is true because my data gathered shows throughout the trials that 400ML of hot water dissolves a tablet of Alka-seltzer in an average of 23 seconds, while a 400ML of cold water dissolves a tablet of Alka-seltzer in an average of 74 seconds. This concludes that a higher temperature make chemical reaction speed up.]]> 2018-06-01 14:40:34 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/265044571 n_solar https://padlet.com/n_solar/ecyxji2v2hl5/wish/265046254 1. Gather all materials at a flat surface. 
2. Run sink on cold for about 5 seconds then pour 400ML of that cold water into the 600ML beaker. 
3. Take one tablet of Alka-seltzer and drop it into the beaker and start the stopwatch simultaneously.
4. Stop the timer when the tablet is completely dissolved.
5. Empty beaker and wash out once.
6. Record data in table and reset timer.
7. Repeat steps 2-6 two more times. 
8. Repeat steps 2-6 again three times except instead of using cold water, use hot water.
9. Gather all lab materials and clean up lab station when done, make sure to turn water off. ]]> 2018-06-01 14:48:31 UTC https://padlet.com/n_solar/ecyxji2v2hl5/wish/265046254
