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.
When you analyze the proteins by electrophoresis, you find that protein B moves further towards the positive end of the gel. Explain if this result is consistent with your hypothesis about the difference between the two proteins.
Explain which of the following substance has the lowest melting point
what is the molar mass of gas if 0.250 g of the gas occupies 215 mL at 61 8mmHg and 30. 0C
Most compounds that contain N-H bonds are basic, but saccharin is acidic
It phosphoresces at 500 nm. If the ratio of the transition probabilities for stimulated emission for the S* --> S to the T --> S transitions is 1.0 x 10^5, what is the half-life of the phosphorescent state
flask "a" has a volume of 0.50 L and contains 50 g of a volatile liquid. Flask "b" has a volume of 1.35L and contains 34.8 g of the same liquis. Both flasks are stoppered and both are at 30C. The ratio of the vapor pressure of the liquid in the fl..
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
Calculate the Sb3+ ion concentration at equilibrium in a 0.10 M Sb3+ ion solution that has been buffered at pH 8.00
