The volume of an average stomach is about 1.0L. Suppose that a particular condition of acid indigestion is equivalent to the presence of a 0.50% HCl (by mass) solution.
Formulas and constants to remember R = 1.98 cal/degree-mole ; Delta G0 = -RT lnKeq. T = 298 degrees K. How much NADH will be produced in the above reaction
Compute the change in temperature when 1.8 g of sodium chloride is dissolved in 300.0 mL of water initially at 20C. The heat capacity of water is 4.184 J/mL/K.
A portable electric water heater transfers 255 watts (W) of power to 5.5 L of water, where 1 W = 1 J/s. How much time (in minutes) will it take to heat the 5.5 L of water from 24 degrees C to 41 degress C? (Assume that the water has a density of 1..
