Lactic acid, C3H6O3, is built in human muscles during anaerobic exercises. If the initial concentration of lactic acid is 0.12 mol/L and the pH is 2.39, what is the Ka for the lactic acid?

Discuss the validity of the statement “All polar bonds molecules must have polar bonds and all non polar molecules must have non polar bonds.”

Consider the following reaction in an open flask:

A 155.0 g sample of CaCO3 is placed in the flask and HCl is added. The reaction consumes HCl at an average rate of 0.200mol/min for 10.0 min. What mass of CaCO3 remains?

CaCO3 + 2HCl = CaCl2 + H2O + CO2

A 155.0 sample of CaCO3 is placed in the flask and HCl is added. The reaction consumes HCl at an average rate of 0.200 mol/min for 10.0 min. What mass of CaCO3 remains? (molar mass Ca=40, C=12, O=16).
