Ionic compounds are compounds composed of a metal as the cation (positive charge) and non-metals as anion (negative charge). Covalent compounds are composed of both non-metals. In this respect, a) water is covalent b) covalent c) ionic d) ionic e) covalent f) ionic.
Number of atoms = mole x Avogadro’s Number
= 0.1 x 6.022 x 10^23
= 6.022 x 10^22
They use Uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission. Nuclear power plants obtain the heat needed to produce steam through a physical process. This process, called fission, entails the splitting of atoms of uranium in a nuclear reactor.

Answer:
2.11 ×10²⁴ atoms
Explanation:
Given data:
Number of moles of NaCl = 3.5 mol
Number of atoms = ?
Solution:
It is known that 1 mole contain 6.022×10²³ atoms. The number 6.022×10²³ is called Avogadro number.
3.5 mol ×6.022×10²³ atoms / 1 mol
21.1 ×10²³ atoms
2.11 ×10²⁴ atoms
Answer:
Key differences between ion/ion and ion/dipole interactions
Ion-ion interactions fall off slower than ion-dipole. Tripling the distance between two ions reduces the energy by 1/3, while tripling the distance between the ion and a dipole reduces it by 1/9
Letter answer: B
