Design a system that produces a constant mass flow rate of 1.00 × 10-2 lbm/s of oxygen from one or more 3.00 ft3 highpressure storage bottles initially at 2000. psia and 400. R.
The oxygen must be delivered at 50.0 ft/s at 60.0°F and 175 psia. The system must operate continuously for six months and must have a fail-safe backup.
Why is the partial charge on a hydrogen atom bonded to a highly electronegative element more concentrated than for any other element?
Cyanogen is a gas which encloses 46.2% C and 53.8% N by mass. At a temperature of 25C as well as a pressure of 750 mm Hg, 1.50 g of cyanogen occupies 0.714 L. Explain what is the molecular formula of cyanogen
Gaseous oxygen is held in two separate containers at identical temperature and pressure. The volume of container A is 6.48 L and it contains 0.785 mol of the gas. The volume of container B id 5.78 L. How many moles of the gas are in container B
What is the pH of the solution formed by adding 2.77 grams of nicotinic acid (M. Wt. = 123.11 g/mol) to 250 ml of 0.050 M NaOH? For Nicotinic Acid Ka=1.4x10-5 and Kb=7.1x10-10
An equilibrium mixture contains N2O4, (P=0.30 atm) and NO2 (P=1.2atm) at 350 K. The volume of the container is doubled at constant temperature. a) Compute the equilibrium pressure of N2O4 when the system reaches a new equilibrium.
Calculate the number of moles of an ideal gas if it has a pressure of 1.21 atm, a volume of 1.68 L, and a temperature of 217 oC. Use R = 0.0821 L-atm/mol-K for the value of the gas constant
The generic metal hydroxide M(OH)2 has Ksp= 6.64x10^-18. (Note: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH from water can be ignored. However, this may not always b..
To what final volume should you dilute 60.0 mL of a 5.90M KI solution so that 20.0 mL of the diluted solution contains 3.30 grams of KI
a sample of ideal gas at room temperature occupies a volume of 23.0l at a pressure of 232torr . if the pressure changes
What are the major components of the mixture after acid-base equilibriums have been established if a) half a mol, b) 2 mol of sulfuric acid (H2SO4) are added to a solution of one mol ketone
Coniine, a toxic substrate solution isolated from poison hemlock, contains only Carbon, Hydrogen, and Nitrogen. combustion analysis of a 5.024g sample yields 13.90mg of CO2 and 6.048mg of H20. what is the empirical formula of Coniine
How to do I calculate the pH of original buffer given mass of NaC2H3O2*H2O (FW =136 g/mol) = 3.507 g
