A piston-cylinder, initially containing 200 mol of helium at 300 K and 0.1 m3 , is expanded to 5 times its original volume by applying 1.5 MJ of heat from a hot reservoir at 400 K. Assuming helium is a van der Waals fluid and with C ∗ P = 29 J/(mol·K), determine the maximum work that can be produced from this process. What is the final temperature of the gas?

Consider the following unbalanced equation for the combustion of hexane: αc6h14(g)+βo2(g)→γco2(g)+δh2o(g) part a balance the equation. give your answer as an ordered set of numbers α, β, γ, use the least possible integers for the coefficients. α α , β, γ, δ = nothing request answer part b determine how many moles of o2 are required to react completely with 5.6 moles c6h14. express your answer using two significant figures. n n = nothing mol request answer provide feedback
