A rigid tank contains 1.30 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 28.2 atm to 4.60 atm. Assume the volume of the tank and the temperature of the gas re
As a side?reaction, organometallic reagents can react with atmospheric CO2 to produce metal carboxylates while the CaCl2 drying tube cannot prevent the incursion of CO2. Explain why this side?reaction is not expected to be problematic in this expe
The average osmotic pressure of blood is 12.3 atm at 27 degree C. what concentration of glucose will be isotonic with blood
When a sample of HI(g) (0.1192 mol/L) is placed in 110.0 L reaction vessel at 968.0 K and allowed to come to equilibrium the mixture contains 0.02028 mol/L of H2(g). What concentration (mol/L) of HI(g) reacted? 2HI(g) = H2(g)+I2(g)
A person ate 0.941 pound of cheese (an energy intake of 7530 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v
