Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃
Answer:
2 half-lives=0.8
6 half-lives= 0.05
Explanation
Half-lives are constant and always decrease by half, implying that the concentration decreases by half at a consistent rate.
3.2/2= 1.6/2= 0.8 is two half-lives
3.2/2= 1.6/2= 0.8/2= 0.4/2= 0.2/2= 0.1/2=0.05 is six half-lives
hydrogen bonding and ion-dipole
Explanation:
The intermolecular forces the particles of fluoride experiences is an ion-dipole bond, between the water molecules, there are hydrogen bonds.
- An ion-dipole bond is an attractive force between an ion and a polar molecule.
- The fluoride is the anion that is attracted by the positive end of water molecules.
- Water is a polar compound.
- Between the water molecule, there is presence of hydrogen bonds.
- Hydrogen bonds are special dipole - dipole attraction between polar molecules joined to a highly electronegative atom.
- The electrostatic attraction between the hydrogen atom of one molecule and the electronegative atom of a neighboring molecule forms the hydrogen bond.
