A sample of gas expands and increases its volume by 2.5 L while pushing a piston against an external force of 2 kPa.

 

What is the work done by the expanding gas?


Given that a fuel cell has two distinct compartments, one for hydrogen oxidation and one for oxygen reduction...

How should the chemical composition of these two compartments be adjusted to obtain the greatest electrochemical potential from the fuel cell?


Use the Nernst equation to adjust this potential for oxygen having a partial pressure of 0.2 bar, which is about its concentration in air.

what is the volume of 15.8 M nitric acid is needed to ensure 1.00 g sample copper completely reacts


The “normal” lead content in human blood is about 0.40 part per million (that is, 0.40 g of lead per million grams of blood). A value of 0.80 part per million (ppm) is considered to be dangerous. How many grams of lead are contained in 6.0 x 103 g of blood (the amount in an average adult) if the lead content is 0.62 ppm?

If a scuba diver releases a 16−mL air bubble below the surface where the pressure is 3.3 atm, what is the volume (in mL) of the bubble when it rises to the surface and the pressure is 1.0 atm?

What is the volume of water produced when 20grams of C7H16 (heptane) is combusted with oxygen.

(C7H16 + O2 = CO2 + H2O)


Calculate the entropy change for 200.0 g of N2 gas that is compressed from a pressure of 0.715

atm to a pressure of 1.16 atm at a constant temperature of 30.0°C. Assume that the gas behaves

ideally.
