How many moles of carbon dioxide (CO₂) are formed when the reaction is allowed to go to completion? Use equation for the question:
37.2 g of methane (CH4) are reacted with excess oxygen (02). The following combustion is allowed to go to completion. (Molar mass of CH4 = 16.0 g/mol)

Ch4(g) + 2O2(g) = CO2 (g) + 2H2O (I)

1.16 mol

2.33 mol

595 mol

298 mol

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.
