GCHEM RECALL! Barium sulfate (BaSO4) is utilized in “barium swallow milkshakes” prior to taking x-rays of the digestive tract. (note: when typing in chemical equations, don’t worry about formatting subscripts, for example BaSO4 = BaSO4 but use parenthesis as needed, for example Na3(PO4) = Na3(PO4) ) 2pt *** a) Write the balanced chemical equation describing how you would prepare BaSO4 from two aqueous solutions resulting in a BaSO4(s) precipitate. (your answer should be in the format of reactants —> products) 2pt *** b) Classify your reaction for blank1 (e.g. neutralization, double replacement, single replacement, etc.) and explain your choice. 1pt *** c) Write an balanced equation for when CaCO3 (the main component in TUMS antacid) reacts with stomach acid, HCl
