Write the balance formula unit equation for the acid-base reaction of calcium hydroxide and hydrobromic acid. 1. What is the the chemical formula of the salt formed in this reaction? 2. If 24.01 mL of 0.110 M calcium hydroxide solution are reacted with 40.62 mL of 0.508 M hydrobromic acid, what is the molar concentration of the salt solution formed in this reaction? 3. what is the molar concentration of the excess reactant once this reaction has finished?
Triethylene glycol, the solvent for your first reaction, and heavy mineral oil are both high boiling, high molecular weight solvents.
The half-life of a reaction, is the time it takes for the reactant concentration to decrease by half. For example, after one half-life the concentration falls from the initial concentration to, after a second half-life to, after a third half-life ..
