Given the balanced chemical equation: 2Cl2(g) + 2H2O(l) --> 4HCl(aq) + O2(g) What is the total number of liters of O2(g) produced when 8 liters of Cl2(g) is reacted with water?

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

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.
