chemical reactions

                               experiment one

  we started the experiment by steel wool and setting it on fire. after setting it on fire it turned a bluish color from the grey.

experiment 2.

we then proceeded to use baking soda and we used the NaH203-h20=co2 thus making it burn and it decomposed into the flames.

 we then di the nail and copper sulfate which caused the copper to bubble . we also did this on zink

the periodic table is shaped like a castle, with the left side being mostly metals and the right being gases. the only acception is hydrogen which is listed as a metal. most of the metals and gases are made into chemical symbols like oxygen is just O and helium is HE these chemical symbols make it a lot easier to determine which metal/gas it is. there is also the affects of the atomic number which s listed below each of the chemical symbols. then there is the mass of each which shows how each each one weighs on the table. the table is also divided into groups and periods. the groups are the vertical sections of the periodic table where the periods are parallel. the periodic table is organized into whether or not it is a metal or a gas. there are also more specific parts to the metals and gases like alkaline metals and noble gases. there are also the electron affinities, which is the electronic power, ionized energy which is the amount of ionic energy per chemical symbol, and atomic radius which does what it says it does it shows the atomic radius, ionic radius which shows the ionic radius, and electronactivity.

flame lab

this week in our class we did a lab on the reorganization in chemical reactions In the release of absorption of heat energy. the chemical formula would turn the chemicals into a different color. like yellow, red, purple, and sparked. in the sr lno327 chemical caused the flame to turn yellow.  the only real inaccuracy would be if you used too much of the chemical formula on the flame. it was easy to figure out the element based off of the color of the flame. the flames on the chemicals are produced by chemical reactions from the heat energy. I think chemicals have to be heated by chemicals.

                                                                     Scientific experiments


             
 observations: we first started by pouring in currite Chloride into a beaker it turned a greenish color. then we mixed it with a copper chloride formula that made it into a bluish mixture. we left it over night and some of the material krystalized over night. then  we took a sample of some of the material . then we sturred it and it turned a reddish color which we poured into a new beaker. we were able to sample some of the krystals which were a purple red color. then we poured some acid on it and left it to form overnight

Oreo Cookie lab

       students measured the filling in three types of Oreo cookies to determine if filling amounts matched advertising

Hypothesis: my hypothesis was that the Oreos did not have a major difference in the stuffing between the Oreos. 

Method: students began to peel stuffing from the original stuffed, double stuffed, and mega stuffed massed each and compared results.

 

the chart below gives the results for this group

                                

original  3.27           4.35.        3.129          2.25        4.35

double   6.17          6.3             6.480         11.3        6.39

mega     8.96         9.4              9.35           17.7        9.04

we concluded that the stuffing actually added up in the end.  the mega stuffed contained more then twice As much as the original stuffed.
