Calculate volume (in L) of CO2 (at s. t.p) produced from iron(III) oxide reacting with carbon monoxide to produce iron.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

it would be a gas formation

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
