Answer:
b) free ions
Explanation:
when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.
I hope this helps you! :D
Answer:
0.05142 M
Explanation:
Let's consider the neutralization reaction between KHP and NaOH.
KHC₈H₄O₄ + NaOH → H₂O + NaKC₈H₄O₄
12.39 mL of 0.04150 M NaOH were required for the neutralization. The moles that reacted are:
12.39 × 10⁻³ L × 0.04150 mol/L = 5.142 × 10⁻⁴ mol
The molar ratio of KHP to NaOH is 1:1. The moles of KHP that reacted are 5.142 × 10⁻⁴ mol.
5.142 × 10⁻⁴ moles of KHP were in 10 mL of solution. The concentration of the KHP solution is:
5.142 × 10⁻⁴ mol / 10 × 10⁻³ L = 0.05142 M
