Limestone consists mainly of the mineral calcite, CaCO3. The carbonate content of 0.541 3 g of powdered limestone was measured by suspending the powder in water, adding 10.00 mL of 1.396 M HCl, and heating to dissolve the solid and expel CO2: with hypobromite, OBr2, by the reaction 2NH3 1 3OBr2 S N2 1 3Br2 1 3H2O. What is the molarity of a hypobromite solution if 1.00 mL of the OBr2 solution reacts with 1.69 mg of NH3

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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".
