Question- what are the identities of the unknown solutions? Why is a flame test able to be used? Evidence- Metal ion Calcium-bright orange  Barium-green/yellow Copper- green Lithium-red Potassium-orange Sodium-yellow/orange Strontium-red/orange Unknown #1- light orange Unknown #2-red/Orange Unknown #3/green/yellow Unknown #4-bright orange  We used our evidence of the unknown metals and compared that to the unknown metals and determined that:   The unknowns were the same shade as the knowns and we incorporated that into finding the answer , although there was some colors we could tell apart based on the shades themselves. The flame test is able to differentiate the amount of electrons which is important because when energy is absorbed by the electron it gets excited and then drops which causes the color of light to appear

How much does beanium weigh? Claim-  beanium weighs about 0.45 g per bean Reasoning -   we   began by separating all the different kind of beans and setting them aside and then we began to weigh them all in their groups as a whole. Then we got the weight and divided it by however many beans there were.  once we got the mass and average mass we figured out the percentages. After that we were able to multiply the averages mass by the percentages and then add them together and divide them by 100 to get a relative mass of a bean.  Evidence  - Limium|Mass= 7.1 g/ Avg= 1.42 g ( 5 beans) 10%                    Kidneyum|Mass= 8.5 g/ Avg= 0.53 g ( 15 beans) 30%                    Peagen| Mass= 7.1 g/ Avg= 0.24 g (30 beans) 60%          (1.42g)(10%)+(0.53g)(30%)+(0.24)(60%)/100= 0.45 g Answer is 0.45 g

Do you get what you paid for? Claim- yes, you do get what you paid for you actually end up getting more than what you paid for. Evidence- Full- 30.40 grams                          30.62 grams 30.50 grams 30.09 grams Empty- 1.54 grams 1.52 grams 1.51 grams 1.53 grams Difference- 28.86 grams 29.1 grams 28.99 grams 28.56 grams Our precision was 0.54 which was more than .20 Reasoning- Accuracy- related to the actual value of the object measured. Precision relates to how small a value can be distinguished by the instrument. We were trying to see if you actually get what you pay for & see how precise and accurate advertising is. first we weighed the bag of chips to see how accurate the weight on the bag was, then we weighed the same bags but empty, after that we calculated how precise the weight was to see if you really ...
