A student does an experiment to determine the specific heat of iron metal. The student repeats the experiment 5 times and gets the following values for specific heat (all in J/g oC): 0.463, 0.449, 0.451, 0.427, and 0.480. The accepted value for the specific heat of iron is 0.450 J/g°C. Required:
a. Calculate the student's percent error. Does the percent error evaluate the accuracy or the precision of the student's measurements? Explain
b. Calculate the standard deviation for the student's data set. Does the standard deviation evaluate the accuracy or the precision of the student's measurements? Explain.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

hi my dude or dudette

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.
