The total volume of seawater is 1.5 1021 L. Assume that seawater contains 3.1 percent sodium chloride by mass and that its density is 1.03 g/mL. Calculate the total mass of sodium chloride in kilograms and in tons. (1 ton = 2000 lb; 1 lb = 453.6 g..
The maximum of the solar emission spectrum is at a wavelength of about 503.0 nm. What is the surface temperature of the sun
What is the Gibbs energy difference across the membrane at 37°C. The difference in concentration must be sustained by coupling to reactions that have at least that difference of Gibbs energy
A system equilibrium at 25 degrees Celsius in a 1.0L container was found to contain 0.0568 moles of BrCl, 0.0216 moles of Br2, and 0.0216 moles of Cl2. If 0.020 moles of BrCl is added to this system, determine the new equilibrium concentrations.
