Answer:
B. It contains 15.0 grams of HNO₃ per 100 grams of solution.
Explanation:
- The percent of a solute in a solution is the mass of the solute (g) per 100 g of solution.
<em>So, an aqueous solution that is 15.0 percent HNO₃ by mass means that It contains 15.0 grams of HNO₃ per 100 grams of solution.</em>
I believe the correct answer from the choices listed above is option A. A direct relationship can be represented by the expression:
y/x = k

Answer: The statement the 
shell holds a minimum number of 
electrons is true.
Explanation:
The alphabet 'n' denotes the principal quantum number whose value can be equal to 1, 2, 3, and so on but can never be zero.
Basically, 'n' is the number of shell of an atom and total number of orbitals present in a shell is 
.
Each orbital can hold up to a maximum of wo electrons. Hence, the shell can hold a minimum number of electrons.
Thus, we ca conclude that the statement the shell holds a minimum number of electrons is true.
The chemical reaction will be NaF
