QUESTION 15 In an experiment, a student obtained the following masses for a product: 0.651 g, 0.643 g, 0.648 g, 0.609 g, and 0.646 g. What is the
percent error?
20.1%
1.90%
0.0122%
Not enough information provided to be able to determine the percent error.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

i think it's letter a.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
