When chromium metal is added to nitric acid, the following reaction takes place
Cr (s) + 6 HNO3 (aq) + Cr(NO3)3 (aq) + 3 H2O (1) + 3,
NO2 (g)
Calculate the volume of NO2 gas (in L) collected over
water at 40.0 °C when 11.1 g of chromium is added to
excess nitric acid if the total pressure is 675.0 torr. The
vapor pressure of water at 40.0 °C is 55.3 torr.

let that person have a turn to speak : )

can you list the answers so i can answer

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".
