My name is Alyssa and i love to play softball. My name is Halie and i love to do track. My name is Alexis and i love to do cheerleading. One thing we all have in common is that we all love art.
 * __Information about us!!!__**

**__April 6th, 2011__** some of our materials are:
 * four mini testubes
 * a graduated cylinder
 * lab scoop
 * Zinc Oxide
 * Copper II Sulfate
 * a testube rack

Are these harmful? [|Topic Link]

Zinc oxide is in plastics, ceramics, glass, cement, and rubber material, lubricants, paints, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, first aid tapes, etc.

__April 7th, 2011__ Expirement.
 * we are using 10 mL of water in the graduated cylinder
 * we are going to pour it into the little test tube
 * we will put a pinch of the Zinc Oxide in one of the test tubes
 * we will put a pinch of the Copper II Sulfate in another test tube
 * we will observe to see if they dissolve in their test tube

Hypothesis: The Zinc oxide will not dissolve but the copper II Sulfate will. Independent variable: Type of solute Dependent variable: Wheter or not the solute dissolves in the water.

chart: (never dissolved) || Obsrvations:
 * Element || Trial1 || Average ||
 * Copper II Sulfate || 3:37 || 3:37 ||
 * Zinc Oxide || 5:12(never dissolved) || 5:12
 * Zinc Oxide is powdery and white.
 * Copper II Sulfate is like a blue crystal.
 * When the Zinc Oxide went in and it got fogy and looked like milk.
 * When the Copper II Sulfate went in it went to the bottom but then it looked like blue gatoraide.
 * The Zinc Oxide looks like its snowing inside of it.
 * The Copper II Sulfate solution is transparent.
 * The Zinc Oxide solutions is opaque and settles into the bottom.


 * When we filtered the Copper II Sulfate solution all went into the flask.
 * When we filtered the Zinc Oxide it all got stuck in the funnel and only the water went into the flask.

__Expirement April 12,2011__ Question: Does the amount of water change the color of the solute DV:concentration IV:amount of water Constant:solute Paper=1.1grams 1.10.mL of water in a test tube 2.20mL of water in the other test tube 3.3g of solute in each testube 4.mix and observe observations:the mixture with 10mL is darker than the 20mL. The 20mL is more diluted.

April 19, 2011 __mystery substance lab:__ our substance turned out to be potassium nitrate.

__April 27th chemical lab__ Calcium Chloride: CaCl 2 Sodium Bicarbonate NaHCO 3 Bromothymol Blue C27H28Br205s
 * harmful to inhale
 * low toxic
 * moderat activity
 * not flamable
 * BP:1600 degrees celcius
 * soluble in water
 * irritates skin(may)
 * baking soda
 * can irritate the eye if eye contact
 * MP:140 degrees Ferenheit
 * not flamable
 * Flamable
 * yellow crystals
 * MP:392-396 degrees Ferenheit

Calcium Chloride and water: start temp:21.1 end:31.0 made water foggy Sodium Bicarbonate and water: start temp:20.1 end:19.2 dissolved in water All together: start temp:22.6 end:24.8 it bubbled up Calcium Chloride and Bromothymol Blue: Start temp:20.9 End:26.7 turned light blue Sodium Bicarbonate and Bromothymol Blue: Start temp:21.3 end:19.2 dissolved Calcium Chloride, Sodium Bicarbonate and water: start:20.6 End:22.1 opaque water Calcium Chloride and Sodium Bicarbonate: start temp:none. end temp:24.9 nothing happened

__Alka-Seltzer lab__ Q:How will the mass of the product and reactants compare? H:The mass of the product will be less than the mass of the reactants IV:mass of reactant(g) DV:mass of product(g) Constant(s): glassware, amount of water(mL) Procedures: 1.mass of glassware with water and reactant. 2.put reactant in lid and put lid on. 3.observe and record mass. 4.take lid off to see how much gas goes out. Masses without the cap: Trial 1 :40.81g Trial 2: 25.51g Trial 3: 25.68g in mass || Summary: Our hypothesis was true for the most pert. We said the mass would go down and we were right. The masses for trial 1 and 2 went down but trial 3 stayed the same. picture of our seltzer in water.
 * Trials || mass of reactant || mass of product || change
 * One || 43.73g || 43.66g || .07g ||
 * Two || 30.33g || 30.32g || .01g ||
 * Three || 30.52g || 30.52g || 0g ||
 * average || 34.86g || 34.83g || .04g ||
