EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

Drug-Drug Interactions (886) Clinically important drug-drug interactions may occur with coadministration of a quinolone with an aluminum- or magnesium-containing antacid‚ theophylline‚ or caffeine. When coadministered with an aluminum- or magnesium containing antacid‚ oral bioavailability of norfloxacin (553)‚ ciprofloxacin (231‚ 290‚ 350‚ 598)‚ ofloxacin (352‚ 475)‚ and perhaps all quinolones is substantially diminished‚ possibly by binding of quinolone to antacid.
