Cold and Hot Packs Explore Lab

Based off the reactants and products we were given, I have designed a cold and hot pack in which are both created using non-toxic nor hazardous reactants or products.

 Cold pack: Ammonium Nitrate          
                    NH4NO3+H2O-> NH4+NO3
                    $9.60 for 500g
Ammonium Nitrate is non- hazardous nor is it toxic. Ammomium Nitrate is actually used as fertilizer which helps increase growth in plants. Ammomium Nitrate is non-flammable however, if it is kept in excessive heat or confined pressure it may cause Ammonium Nitrate to explod but is very unlikely for that to occur. In the lab, ammomium Nitrate's initial temperature was 25.8°c and dropped to a lower temperature of 12.9°c which means it is endothermic since heat was absorbed.

Hot Pack: Magnesium Sulfate
                   MgSO4+H2O-> Mg+SO4
Magnesium Sulfate is a non-organic salt or mineral that is completely safe and non toxic. In the lab, magnesium sulfates initial temperature was 25.8°c and rose to a temperature of 28.0°c which shows that it is exothermic because heat was released.

•NH4Cl+Ba (OH)2-> BaCl2+H2O+ NH3
•HC6H7O7+NaHCO3-> NaC6H7O6+H20+CO2
•CaCl2+H2O-> Ca+2Cl
 All these reactants and products are toxic and hazardous because the top two are chemical compounds that can be flammable and cause serious health issues.

                 

3 question blog 3/25

1. Recently, I have completed the stoichiometry test for chemistry. Two chaper tests for sociology. As well as a vocabulary test for english.

2. I have learned how much sleep affects a human being. If we do not get as much sleep it can lead to several illnesses. I have also learned how to calculate stoichiometry equations. Last but not least, I have learned how people act certain ways because of the norms we have in today's culture.

3.Next, I plan to complete a lab that examines what activation energy. I will work on completing the article readings for my sociology class. Lastly, I will work on focusing more and being proficient in the tasks I need to complete.

1) Recently I have completed a test for my sociology class. I have also completed reviews for test for several of my classes. And have also completed notes in chem.

2) Recently I have learned the different types of research methods. I have also learned how to do stoichiometry for my chem class using the white boards to help grasp a better understanding. I have also learned about the stages of adulthood and death in my psychology class.

3) Next I plan on completing my test corrections for chem. I also plan on reading for my sociology class. One last thing I plan on doing is taking the stoichiometry test and being proficient.

One last thing.....
