Explain carbon dioxide gas evolved out from the solution

Reference no: EM13251405

To a sample of alkaline earth metal carbonate (MCO 3; 0.250g) was added 10.0mL HCl (0.40M). Carbon dioxide gas evolved out from the solution. After the reaction was completed. The solution was back titrated with a NaOH solution (3.05mL, 0.1500M). Write the reaction equation for the reaction of MCO3 and HCl;

Calculated the Molecular Mass of MCO3 and determine what is this sample: CaCO3; MgCO3; or BaCO3?
