The rusting of iron is represented by the balanced chemical equation below. If you have a 3.50 gram sample of iron, how many moles of Fe2O3 will there be after the iron has rusted (reacted) completely? PRO TIP: Don't enter units. Just enter the correct number in decimal format rounded to the correct number of significant figures.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
