The answer is (1) absorbing energy. The electrons just change the shell position. So there is no losing or gaining. And the outer shell has higher energy than inner shell. So the atom is absorbing energy.
Answer : The concentration of solution is, 8.53 M.
Explanation :
As we are given, 45.0 mass % solution of ethanol in water that means 45.0 g of ethanol present in 100 g of solution.
First we have to calculate the volume of solution.
Now we have to calculate the molarity of solution.
Mass of = 45.0 g
Volume of solution = 114.5 mL
Molar mass of = 46.07 g/mole
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the concentration of solution is, 8.53 M.
Whichever one has the smallest amount of H+ Ions.

Answer: 448254.609 mm³ OR 4.48 × 10⁵ mm³ </h2>
Explanation:
Volume = Mass ÷ Density
= 0.08 g ÷ 0.17847 g/L
= 0.448254609 L
since 1 L = 1,000,000 mm³
then 0.448254609 L = 448254.609 mm³
