<span>Out of the possible answers for this question, fluorine in the second period is correct. Of the four elements fluorine, chlorine, bromine and iodine, fluorine has the largest first ionization energy, with a Enthalpy number of 1681.0. Of all the elements, helium has the highest first ionization energy figure.</span>
Answer:
A - Chemical potential energy being converted to heat energy
Explanation:
Answer:
28%
Explanation:
concentration=(solute mass/solution mass)*100
C=concentration
md-solute mass
ms-solution mass
the solution mass is equal to the sum of the solute and solvent mass
ms=3.82+1.49=5.31lb
c=1.49/5.31 * 100=0.28*100=28%
