Use the mole ratio of hydrogen to oxygen from question #4 to determine what happens when various hydrogen/oxygen gas mixtures are allowed to burn. Complete the following table to indicate which reactant (H2 or O2) is present in excess, and how much of it will be left over after the combustion reaction is complete. parts h2. 6 5 4 3 2 1 0

parts 02. 0 1 2 3 4 5 6

which reactant is present in excess?

How much of that reactant is left over?​

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

plasma - state of matter made up of electrically charged particles

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.
