====The purpose of the lab was to fined out differences in chemical reaction when the temperature change. Chemical reaction is a change in matter that produces new substances. Examples of chemical reactions that was observed in the experiment were color change, and bubbling. my original prediction was that using hot water out of the tap, the rate of reaction will be 3 times faster that at 0 degrees C. we've done three trials with hot tap water, cold water, and room temperature water in the lab. In the first trial with the room temperature, the temperature was 16.4 degrees Celsius and it dissolved in 1:22 seconds. In the second trial which was with the hot tap water was 70.4 degrees Celsius dissolved in 20.4 seconds. The third trial was with the ice water was 2.4 degrees Celsius dissolved in 2:55 seconds. The evidences that I saw in trials were that it made bubble, it changed color to orange, and it made a sizzling noise. ====

Experiment #3: Release of a Gas

in this experiment video they are using release of gas to see some chemical reaction. They use… a Ziploc bag, a napkin or paper towel, ¼ of a cup of baking soda, ½ of a cup of vinegar, and ½ of a cup of water. First, they put the baking soda into a paper towel and set that aside. Then they mix the vinegar and water into a Ziploc bag. Lastly, they pour the baking soda from the paper towel into the Ziploc bag with the vinegar and water mixture. The mixture started to bubble and expanded. It even made the bag exploded. It was the one of evidence that a chemical reaction. In this experiment there weren’t any factors that affected the speed of this reaction. In everyday life, this experiment might happen. This is because baking soda and vinegar are daily baking items, and if they are possibly combined they might just explode like they did in this experiment. Trying this experiment actually would be fun because it would be interesting to see it bubble and make the bag explode.

=== In class we were researching stuff about a compound that we are assigned to do, and make a model on. We had to make a popplet which we had never used before so it was a new web tool. Popplet wasn’t a very hard tool to use, because it similar prezi.I had no trouble at all making a popplet, but it was littlebit hard to do research on cyclohexane, but it was fun to use new tool. We had to research 4 parts to the element its history, examples of the compounds, atomic structure, and its type of bond. One thing I learned from this activity is that cyclohexane is a covelant bond meaning that it shares its atom. Overall I found this activity to be a fun, and new exciting way to learn how to use a new tool. ===



3. you can separate a water sand suspension with a strainer. you would have to boil the solution to separate the water and sugar.
Hypothesis I think liquid would dissolve better in liquid than solid Data table
 * Substance || Solid /Liquid || Soluble/Non Soluble ||
 * Salt || Solid || Soluble ||
 * Sugar || Solid || Soluble ||
 * Vinegar || Liquid || Soluble ||
 * Rubbing alcohol || Liquid || Soluble ||
 * Pepper || Solid || Non Soluble ||
 * Powdered chalk || Solid || Non Soluble ||
 * Baking soda || Solid || Soluble ||
 * Corn starch || Solid || Soluble ||
 * Vegetable oil || Liquid || Non Soluble ||

Result

Conclusion My hypothesis was that liquid dissolved better.
 * Was the hypothesis correct?

Solid seem to dissolve better.
 * What substances appeared to dissolve better, solids, liquids, or neither?

It was polar.
 * Is water polar or non polar?

They combined with substances that we dissolved in.
 * How do the molecules react in water?

There was no residue left it was completely gone.
 * What observations did you see that indicated they dissolved?
