Answer and Explanation: The full ground-state electron configuration for a fluorine atom is 1s2, 2s2, 2p5. We determine this by first identifying the number of electrons in a fluorine atom. If the atom is neutral, it will have nine electrons to match the nine protons int he fluorine nucleus
The answer is: [D]: " AgCl " .

Given the chemical reaction:
_________________________________________________________
NaCl (aq) + AgNO₃ (aq) <span>→ </span> NaNO₃ (aq) + AgCl (s) ;
_________________________________________________________
The "reactants" , which are on the "left-hand side" of the chemical equation, are:
"NaCl" (in aqueous solution); and "AgNO₃" (in aqueous solution).
The "products", which are on the "right-hand side" of the chemical equation, are:
"NaNO₃" (in aqueous solution); and: "AgCl" (as a "solid").
The "AgCl" (as a "product"—which is a "solid"—would be the "precipitate" ;

→ which is: Answer choice: [D]: " AgCl " .

Explanation:
Answer:
We need 113000 J of heat (option 2 is correct)
Explanation:
Step 1: Data given
Mass of liquid water = 50.0 grams
ΔHVap = 2260 J/g
Temperature = 100 °C
ΔHVap = The amount of heat released to change phase of a liquid water to steam = 2260 J/g
Step 2: Calculate the heat needed
Q =m* ΔHVap
⇒with Q = the amount of heat needed = TO BE DETERMINED
⇒with m = the mass of water = 50.0 grams
⇒with ΔHVap = 2260 J/g
Q = 50.0 grams * 2260 J
Q = 113000 J
We need 113000 J of heat (option 2 is correct)
