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
1. Recently we have completed our atomic structure and electromagnetic radiation explore lab 2. Recently we have learned about certain identities of chemicals, emissions, and worked with solutions 3. I plan to created flash cards and practice est to better help me understand the work and to prepare for tests
