The reaction of calcium bicarbonate, Ca(HCO3)2 with hydrochloric acid, HCl, produces a solution of CaCl2, gaseous carbon dioxide, CO2, and water, H2O. Write a balanced chemical equation for this reaction and determine the volume of CO2, in mL, that forms at 30.0 oC and 0.660 atm upon reacting 40.3 mL of 0.200 M Ca(HCO3)2 with excess HCl.
Explain the large disparity in the numerical results pf Part (a). Discuss the advantages and disadvantages of the three energy sources.
write the full chemical equation upon the addition of NaOH to each of the 3 alanine species mentioned. If there's no reaction, indicate there's no reaction and why.
Complete and balance the equation for this reaction in acidic solution. Phases are optional.
