This is a magical place, but even some things that appear magical have an explanation. Magic involves energy.
Demonstrate your knowledge on a related phenomenon, Energy Transformation, by copying and pasting the following questions into your OneNote Notebook and drawing your answer.
DIRECTIONS
Make a sketch in your science notebook that traces all of the changes in energy that occur from start to finish in these scenarios:
Scenario 1
Start: An apple grown on a tree provides nourishment for a hungry teenager.
End: The student wins the 100-yard dash event in the track meet.
Scenario 2

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
