The reaction is actually endothermic because delta H is positive, indicating that it absorbing heat.
A Lithium atom that has lost ONE Electron, is called a Lithium Ion (Li+).
So the question ask to calculate the equilibrium and ask on which of the following choices is the possible reaction and based on my calculation and the use of the formula i came up with an answer of letter B. I hope you are satisfied with my answer and feel free to ask for more.
That statement is True
The components of a true solution consist of homogenous mixture which substance dissolved in a solvent. Later on, this components will blend with others and form new properties
hope this helps
