Answer from: mya2019

The formation of an aqueous LiBr solution occurs according to the following reaction: $\boxed{{\text{LiBr}}\left( s \right)+{{\text{H}}_{\text{2}}}{\text{O}}\left( l \right)\to {\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{B}}{{\text{r}}^ - }\left({aq}\right)}$

Further Explanation:

Chemical bond:

The attraction between atoms, molecules or ions that is responsible for the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding also exist.

Ionic compound:

As the name suggests, these compounds have ions as their constituent particles. Out of two bonded atoms, one forms cation by the loss of electrons while other become anion by the gain of electrons.

Properties of ionic compounds:

1. Hard solids

2. High melting and boiling points.

3. Good conductors of heat and electricity.

4. High enthalpy of fusion.

LiBr is an ionic compound that is composed of ${\text{L}}{{\text{i}}^ + }$ and ${\text{B}}{{\text{r}}^ - }$ ions. Water is a polar molecule. When LiBr is dissolved in water, it dissociates into its respective ions. ${\text{L}}{{\text{i}}^ + }$ ions get surrounded by ${\text{O}}{{\text{H}}^ - }$ ions of water and ${\text{B}}{{\text{r}}^ - }$ ions are surrounded by ${{\text{H}}^ + }$ ions of water. So solid LiBr is converted to its aqueous solution when dissolved in water.

The reaction occurs as follows:

${\text{LiBr}}\left( s \right)+{{\text{H}}_{\text{2}}}{\text{O}}\left( l \right)\to{\text{L}}{{\text{i}}^ + }\left({aq}\right)+{\text{B}}{{\text{r}}^ - }\left({aq}\right)$

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
