Dalton's law of multiple proportions can be applied to What is the correct name for FeCl3? Zinc oxide is found in ointments for the skin. What formula best describes this compound, which has Zn as a doubly charged cation? What is the proper name for Co(CI04)3? Buffer solutions that maintain certain levels of pH or acidity are widely used in biochemical experiments. One common buffer system uses sodium dihydrogenphosphate and sodium monohydrogenphosphate. What are the formulas of these two compounds? A fuel cell works on the same principle as a battery but is continually fed with fuel. In one fuel cell, methanol (CH3OH) enters on one side of the unit, and air enters on the other side. Both circulate past electrodes, and a chemical reaction occurs that produces electricity plus carbon dioxide and water as byproducts. Which chemical reaction equation best represents the reaction that occurs in this fuel cell? The average adult exhales about 1.0 kg of carbon dioxide each day. How much glucose (C6H12O6, 180 g/mol) is consumed to make that much carbon dioxide? A reaction vessel contains equal masses of iron and oxygen.
