What volume of O2 (at 0.851 atm and 22.9 C) is produced by the decomposition of 5.59 kg of HgO?

2 HgO(s) --> 2 Hg(l) + O2(g) V = ___ L

charge q_A and q_B separated by a distance L = 12 m, see figure. The potential V is zero at a distance a = 3.9 m. Find the charge q_A if q_B = -2.7 C.

Using the Born approximation, obtain an integral expression for the total cross section for scattering of particles of mass m from the attractive Yukawa potential V(r) = - V0 exp [ -(r/a)²]

Show by direct substitution for vf and vi that the ideal gas law implies PΔV = vRΔT when P and V are constant, where ΔV = Vf-Vi and ΔT = Tf −Ti

Draw the modern Phillips Curve and assume v of the Phillips Curve is 1. Show and explain the effects of the crisis. By exactly how much should inflation change? Be sure to label everything.

For Van Der Waals equation

(P + a/V2)(V - b) = nRT

How can you find the values of "a" and "b" using an experiment? Please explain the method of the experiment too

A typical H2–O2 PEMFC might operate at a voltage of 0.75 V and λ = 1.10. At STP, what is the efficiency of such a fuel cell (use HHV and assume pure oxygen at the cathode)?
