The electron configuration for Fluorine is 1s 2 2s 2 2p 5 a. How many total electrons does Fluorine have?
b. How many of these electrons are in the 1 st energy level?
c. How many of these electrons are in the 2 nd energy level?
d. If you could see the two different “s” orbitals, how would 1s differ from 2s?

Need on both questionswill markbr />

What’s the percent by mass of carbon in c10h14n2

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
