The reaction of solid carbon with oxygen gas to form carbon dioxide gas.

When solid carbon reacts with oxygen molecule, it leads to the production of carbon dioxide gas. The chemical equation for the formation of carbon dioxide follows: By Stoichiometry of the reaction: 1 mole of solid carbon reacts with 1 mole of oxygen gas to produce 1 mole of carbon dioxide gas.

i think is conclusions.i think so

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.
