Question

6 In Part C, which of the anta heartburn? Use the information you o which of the antacids you tested would be the most effective at neutralizing stomach acid to w a offerences in the effectiveness of the antacids you tested e the information you obtained from the antacid package labels to offer an explanation for the some antacids produce bubbles when they react with acids. The bubbles are carbon dioxide (CO) released by decomposition of carbonic acid (H.CO) produced in the paralization reaction. Did any of the antacids you tested in Part C produce bubbles when added to the HCl solution? Name the active ingredient(s). Write a balanced chemical equation to describe the neutralization reaction and the source of H.CO, from the antacid 8 Consider your data for Part D. and answer the following questions a Which solution was the most effective at resisting a change in pH when this difference in behavior compared to the other solutions. I was added? Offer an explanation for b Which solution was the most effective at resisting a change in pH when NaOH was added? Offer an explanation for this difference in behavior compared to the other solutions e Did the buffer solution (test tube 4) ever demonstrate a large change in pH? If so, how much acid or base was added to cause this change? Propose an explanation for why the buffer might have been unable to resist changes in pH under these circumstances. Aspirin is an acidic compound. Many aspirin products (e.g., Bufferin") contain antacids in addition to the drug itself. Why might this be a useful addition to the medication?

Answer 1

a compounds composed only of carb. on and hydrogen - Hydrocarbon b. class of hydrocarbons that con- tain only single bonds. Saturated OR Alkanes e compounds that share a molecu- lar formula but have different Structures. L structural isomer. d. Hydrocarbons that contain double oro triple bonds. L Unsaturated) e compounds with the same molecu- I lar formula that differs in the way atoms are connected. L Constitutional isomer

f. class of hydrocarbons that may inconporate one or more ben- zene rings in their stroucture. L Aromatic

2. Here the given molecular forme- la – Co H60 = Co H 2 x 2 +2 0 = Cn Hgn+20 So the compounds may be either acyclic ether on alcohol So, the compounds are - CH₂-O- CH₂ ethanol sime thyl ether

isomer Lewis structure can be given of both as - H I - - HC -o-c-H F-U - U- H-c-c-0-H # H I- F H I (ethano) (Dimethylether).
