2. Consider the reaction: CaCl2 (ag) + 2 AgNO3 (ag) → 2 AgCl (s) + Ca(NO3)2 (ag)
How many grams of AgCl precipitate is produced if 0.250 L of 0.120 M AgNO3 reacts with
plenty of CaCl2?

gravity causes stares to cluster i think so

what does the table look like

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.
