Flame Test Lab

 



Introduction: Some metals ions can be identified by the color of their flame during a flame test. Different elements placed into a flame will turn the flame different colors.

Essential Question: What metals do colors indicate?  

 

chemical formula                                Name of metal                                   Color Produced

CuCl2                                                         copper                                                       Green

KNO3                                                         Potassium                                              Pink & Purple

Sr(NO3z)                                                    Strontium                                                    Red

CoCl3                                                         Cobalt                                                         Green

LiNo3                                                         lithium                                                     Red & Orange

MgCl2                                                        Magnesium                                            White-ish Sparks

KNO3                                                         Potassium                                                Pink & Purple

 

Questions: 1 - The inaccuracies involved when using a flame for identification purposes?

If your color blind you wont be able to recognize the colors correctly.

2 - it was easy to recognize elements that I didn't know is when they came up I would just right them down and look them up later.  

law of conservation of mass

 

 

part A
1st trial - 5.288g
2nd trial - 4.317g             <---- 1. Mass of apparatus before mixing
3rd trial - 5.387g
2. observations on mixing - turned white, a little bubbly
3. mass of apparatus after mixing.
1st trial - 5.450g
2nd trial - 4.941g
3rd trial - 6.137g

Part B
1st trial - 68.2
2nd trial - 63.4                <----- 1. mass of bottle, water , cap, and tablet
3nd trial - 65.3
2. observations after mixing - bubbling, dissolves
3. mass of apparatus after mixing
1st trial - 33.6
2nd trial - 40.5
3rd trial - 32.1
4. mass of apparatus after opening.
1st trial - 25.5
2nd trial - 22.9
3rd trial - 29.3
Part c
1. mass of apparatus before mixing.
1st trial - 3.962
2nd trial - 3.962
3rd trial - 3.948
2. observations on mixing - turned white
3. mass of apparatus after mixing.
1st trial - 3.919
2nd trial - 3.986
3rd trial - 3.918

1. for each experiment list the observations that suggest that a chemical reaction has taken place.
Part A
1st trial - 0.162
2nd trial - 0.624
3rd trial - 0.75
Part B
1st trial - a. 34.6  b.42.7
2nd trial - a. 22.9 b. 40.5
3rd trial - a. 33.2 b. 36
2. Part A = dropped
Part B = dropped then raised
Part C = dropped the raised then dropped again
3. yes because they are all close to each other

Oreo Cookie Lab

Oreo Cookie Lab

By Anthony Scibilia, Damien Pevear, and Kenny Carnes

Sept. 12, 2013

 

We measured the filling in the three types of Oreo Cookies to determine if filling amounts matched advertising (regular, Double stuff, Mega)

Hypothesis: We think the Oreos will have double then triple the amount of the original.
Method: Step 1 - Measure each Oreos filling
           Step 2 - Weigh The Oreos Filling
    Step 3 - Compare the masses
Results: First Napkin - .65          First Oreo Filling - 3.5g -> 2.85g
Second Napkin - .65              Second Oreo Filling - 6.98g -> 6.33g
Third Napkin - 1g              Third Oreo Filling - 9.9g -> 8.9g
Conclusion: We concluded that the filling is double and mega (x2 and x3)

Physical Science

Why i took this course

1. We can make bottle rockets

2. Knowledge of different ecosystems

3. to understand the environment
